Podcasts about reprap

This Episodes Questions: Hello to a fellow Hoosier and the J's, I have almost bought a printer for at least 15 years, almost bought a makerbot, almost bought a RepRap, but always got discouraged at their difficulty to use. I put purchasing one on the back burner. In December 2024 I purchased a Bambu P1S. This printer is great and just works. But, it's boring. I need to tinker. I'm just a hobbyist at this point. I can see making and selling stuff down the road. My question is which printer on the market now is in need of more user input to operate? Something more equivalent to driving a manual transmission versus an automatic. Thanks. Clint Just found your podcast and I'm binging it from the beginning forward. I apologize if you've tackled this before- As a very low volume hobbyist, I find myself  infrequently printing one or two of a small item I've identified a need for. Here, time, within reason, is no issue. I dont really care if a part takes 2 hours or 6 hours to print. Print quality, however, is an issue. So I'd sacrifice a great deal of speed to get better quality on the first try Do you have advice for settings  that prioritize quality over speed?  Thank you!! Gregory I am looking at a flashforge 5m pro, k1c, or flsun t1 pro as a first printer. All three are very close in cost. I have some cnc experience but no 3d printing experience. I am looking for a fast way to prototype and will eventually want to use nylon and cf materials.  I would love a bigger printer but believe it is probably better to stay small for now. Things I care about. 1. Ease of use. Easily number one. 2. Safety/ filtering, although I know i can add filters. 3. Consistency 4. Versatility. 5. I'm not interested in bambu. Again, thanks for your time and love the podcast. Appreciate any insight you can give me. Cheers. Lewis

On this episode of the Additive Insight podcast, we're joined by Prusa Research founder and CEO Josef Prusa. Prusa was founded in 2012 off the back of the RepRap movement and has gone on to become one of the most renowned manufacturers of desktop FDM and SLA 3D printers. At Formnext 2024, Prusa sat down with TCT Group Content Manager Sam Davies to discuss the company's rise, the evolution of its product portfolio, why open sourcing has always remained important for the company, and where he wants to take the business next.

This Episodes Questions: Hey guys! Long time listener, first time caller! I recently took home an old(ish) Fusion3 F410. (Our department at work wanted to get rid of it.) We also have a Raise3d Pro3, BambuLab X1C and X1E, so this thing is a real pain to use in comparison. About the only good thing it has going for it is the big build volume (355x355x315), other than that there are a couple of annoyances: - Glass build plate - Auto bed-leveling is hit or miss. It only probes the 4 corners where aluminum tape is used for conductivity. - Reaaally long Bowden tube setup - Weird kevlar string used for the X-Y motion system.. but I guess it works. - Old Duet2 board and RepRap software - Discontinued by Fusion3 I volunteered to take it home because I have some ideas! I want to see if I can breath new life into it with some mods: - Magnetic PEI build plate - Direct-drive extruder on the toolhead - BigTreeTech control board and Klipper Do you guys have any suggestions on how to get the above mods done? I'm not too familiar with Voron printers, but I wonder how much I can pull from their large-format printers as far as parts, electronics used, etc. I can design/print custom part solutions if needed, and have access to sheet metal for the bed. I also have some experience with Klipper, and I think getting that properly configured will be an undertaking on its own. Thanks! Matt Hi guys,I recently stumbled over your podcast and really like the bandwidth of topics you guys talk about! Currently I own 2x K1 Max but will soon replace 1 of them by a K2 Plus. You guys are talking a lot about creating your own configuration settings for materials and such. I would really like to know how should someone approach this systematically. Let's imagine I have Creality print 5.1 ;-) which is splitting all settings on one side to a Filament setting and on the other side to the different layer height configurations. Lately I had a standard PLA - which caused problems - and ended up by changing the temperature in the Filament settings and the max speed in the layer height configuration. This solved the problem but I will never have just one setting to load for this material. So now there are actually two questions: - How to approach a perfect setting for a material (and height) systematically? - Any tips and tricks for Creality Print 5.1 on how to manage multiple settings? Thanks a lot and keep up the good work! Michael from Switzerland

On this episode of the Additive Insight podcast, we're joined by Adrian Bowyer, the founder of the RepRap movement and a TCT Hall of Famer. Bowyer, a former mechanical engineering academic, came to prominence within the 3D printing world around 20 years ago when he shared a blog on the Bath University website detailing the idea for a replicating rapid prototyper. Once published, he was encouraged to take the lead on the project, and what came next was a movement that attracted the support of hobbyists and consumerists all over the world. Throughout today's episode, Bowyer discusses the motivations behind the RepRap movement, how the RepRap machines evolved through the generations, and the decision to sell of the RepRap Pro business. He also provides his assessment of the desktop printer market that spawned from the RepRap movement and how AI might impact 3D printing.

Just over 20 years ago the #RepRap project was started by Dr. Adrian Bowyer and ever since the consumer 3D printing industry has NEVER been the same! Being that RepRap just celebrated 20 years, lets talk all about hoe RepRap has shaped this community to what we see today! Topics to Cover: What is RepRap? Why should I care about RepRap? Is RepRap still around today? Will the ideals of RepRap survive? AND MORE!!!

First time from a new studio!

On this Podcast episode, Stefan shares his latest acquisition, the Vectorfinesse's 3D-printed headphones. The discussion then shifts to his recent trip to Loveland, Colorado, where he attended the Rocky Mountain RepRap Festival. Stefan shares some of the projects he witnessed and highlights the differences between this new event and MRRF and ERRF. The conversation moves on to the upcoming REVO high flow and their experience with Prusa's new MK4. Stefan also recounts his exciting experience driving a Tesla 3 rental in LA and collaborating with William Osman for a video. Lastly, the hosts tackle a listener's question about how to dispose of a solar battery and give pointers on building one.

One of the hardest parts of telling any history, is which innovations are significant enough to warrant mention. Too much, and the history is so vast that it can't be told. Too few, and it's incomplete. Arguably, no history is ever complete. Yet there's a critical path of innovation to get where we are today, and hundreds of smaller innovations that get missed along the way, or are out of scope for this exact story. Children have probably been placing sand into buckets to make sandcastles since the beginning of time. Bricks have survived from round 7500BC in modern-day Turkey where humans made molds to allow clay to dry and bake in the sun until it formed bricks. Bricks that could be stacked. And it wasn't long before molds were used for more. Now we can just print a mold on a 3d printer.   A mold is simply a block with a hollow cavity that allows putting some material in there. People then allow it to set and pull out a shape. Humanity has known how to do this for more than 6,000 years, initially with lost wax casting with statues surviving from the Indus Valley Civilization, stretching between parts of modern day Pakistan and India. That evolved to allow casting in gold and silver and copper and then flourished in the Bronze Age when stone molds were used to cast axes around 3,000 BCE. The Egyptians used plaster to cast molds of the heads of rulers. So molds and then casting were known throughout the time of the earliest written works and so the beginning of civilization. The next few thousand years saw humanity learn to pack more into those molds, to replace objects from nature with those we made synthetically, and ultimately molding and casting did its part on the path to industrialization. As we came out of the industrial revolution, the impact of all these technologies gave us more and more options both in terms of free time as humans to think as well as new modes of thinking. And so in 1868 John Wesley Hyatt invented injection molding, patenting the machine in 1872. And we were able to mass produce not just with metal and glass and clay but with synthetics. And more options came but that whole idea of a mold to avoid manual carving and be able to produce replicas stretched back far into the history of humanity. So here we are on the precipice of yet another world-changing technology becoming ubiquitous. And yet not. 3d printing still feels like a hobbyists journey rather than a mature technology like we see in science fiction shows like Star Trek with their replicators or printing a gun in the Netflix show Lost In Space. In fact the initial idea of 3d printing came from a story called Things Pass By written all the way back in 1945! I have a love-hate relationship with 3D printing. Some jobs just work out great. Others feel very much like personal computers in the hobbyist era - just hacking away until things work. It's usually my fault when things go awry. Just as it was when I wanted to print things out on the dot matrix printer on the Apple II. Maybe I fed the paper crooked or didn't check that there was ink first or sent the print job using the wrong driver. One of the many things that could go wrong.  But those fast prints don't match with the reality of leveling and cleaning nozzles and waiting for them to heat up and pulling filament out of weird places (how did it get there, exactly)! Or printing 10 add-ons for a printer to make it work the way it probably should have out of the box.  Another area where 3d printing is similar to the early days of the personal computer revolution is that there are a few different types of technology in use today. These include color-jet printing (CJP), direct metal printing (DMP), fused deposition modeling (FDM), Laser Additive Manufacturing (LAM, multi-jet printing (MJP), stereolithography (SLA), selective laser melting (SLM), and selective laser sintering (SLS). Each could be better for a given type of print job to be done. Some forms have flourished while others are either their infancy or have been abandoned like extinct languages. Language isolates are languages that don't fit into other families. Many are the last in a branch of a larger language family tree. Others come out of geographically isolated groups. Technology also has isolates. Konrad Zuse built computers in pre-World War II Germany and after that aren't considered to influence other computers. In other words, every technology seems to have a couple of false starts. Hideo Kodama filed the first patent to 3d print in 1980 - but his method of using UV lights to harden material doesn't get commercialized.  Another type of 3d printing includes printers that were inkjets that shot metal alloys onto surfaces. Inkjet printing was invented by Ichiro Endo at Canon in the 1950s, supposedly when he left a hot iron on a pen and ink bubbled out. Thus the “Bubble jet” printer. And Jon Vaught at HP was working on the same idea at about the same time. These were patented and used to print images from computers over the coming decades. Johannes Gottwald patented a printer like this in 1971. Experiments continued through the 1970s when companies like Exxon were trying to improve various prototyping processes. Some of their engineers joined an inventor Robert Howard in the early 1980s to found a company called Howtek and they produced the Pixelmaster, using hot-melt inks to increment the ink jet with solid inks, which then went on to be used by Sanders Prototype, which evolved into a company called Solidscape to market the Modelmaker. And some have been used to print solar cells, living cells, tissue, and even edible birthday cakes. That same technique is available with a number of different solutions but isn't the most widely marketable amongst the types of 3D printers available. SLA There's often a root from which most technology of the day is derived. Charles, or Chuck, Hull coined the term stereolithography, where he could lay down small layers of an object and then cure the object with UV light, much as the dentists do with fillings today. This is made possibly by photopolymers, or plastics that are easily cured by an ultraviolet light. He then invented the stereolithography apparatus, or SLA for short, a machine that printed from the bottom to the top by focusing a laser on photopolymer while in a liquid form to cure the plastic into place. He worked on it in 1983, filed the patent in 1984, and was granted the patent in 1986.  Hull also developed a file format for 3D printing called STL. STL files describe the surface of a three-dimensional object, geometrically using Cartesian coordinates. Describing coordinates and vectors means we can make objects bigger or smaller when we're ready to print them. 3D printers print using layers, or slices. Those can change based on the filament on the head of a modern printer, the size of the liquid being cured, and even the heat of a nozzle. So the STL file gets put into a slicer that then converts the coordinates on the outside to the polygons that are cured. These are polygons in layers, so they may appear striated rather than perfectly curved according to the size of the layers. However, more layers take more time and energy. Such is the evolution of 3D printing. Hull then founded a company called 3D Systems in Valencia California to take his innovation to market. They sold their first printer, the SLA-1 in 1988. New technologies start out big and expensive. And that was the case with 3D Systems. They initially sold to large engineering companies but when solid-state lasers came along in 1996 they were able to provide better systems for cheaper.  Languages also have other branches. Another branch in 3d printing came in 1987, just before the first SLA-1 was sold.  Carl Deckard  and his academic adviser Joe Beaman at the University of Texas worked on a DARPA grant to experiment with creating physical objects with lasers. They formed a company to take their solution to market called DTM and filed a patent for what they called selective laser sintering. This compacts and hardens a material with a heat source without having to liquify it. So a laser, guided by a computer, can move around a material and harden areas to produce a 3D model. Now in addition to SLA we had a second option, with the release of the Sinterstation 2500plus. Then 3D Systems then acquired DTM for $45 million in 2001. FDM After Hull published his findings for SLA and created the STL format, other standards we use today emerged. FDM is short for Fused Deposition Modeling and was created by Scott Crump in 1989. He then started a company with his wife Lisa to take the product to market, taking the company public in 1994. Crump's first patent expired in 2009.  In addition to FDM, there are other formats and techniques. AeroMat made the first 3D printer that could produce metal in 1997. These use a laser additive manufacturing process, where lasers fuse powdered titanium alloys. Some go the opposite direction and create out of bacteria or tissue. That began in 1999, when Wake Forest Institute of Regenerative medicine grew a 3D printed urinary bladder in a lab to be used as a transplant. We now call this bioprinting and can take tissue and lasers to rebuild damaged organs or even create a new organ. Organs are still in their infancy with success trials on smaller animals like rabbits. Another aspect is printing dinner using cell fibers from cows or other animals. There are a number of types of materials used in 3D printing. Most printers today use a continuous feed of one of these filaments, or small coiled fibers of thermoplastics that melt instead of burn when they're heated up. The most common in use today is PLA, or polylactic acid, is a plastic initially created by Wall Carothers of DuPont, the same person that brought us nylon, neoprene, and other plastic derivatives. It typically melts between 200 and 260 degrees Celsius. Printers can also take ABS filament, which is short for acrylonitrile-butadien-styerene. Other filament types include HIPS, PET, CPE, PVA, and their derivative forms.  Filament is fed into a heated extruder assembly that melts the plastic. Once melted, filament extrudes into place through a nozzle as a motor sends the nozzle on a x and y axis per layer.  Once a layer of plastic is finished being delivered to the areas required to make up the desired slice, the motor moves the extruder assembly up or down on a z axis between layers. Filament is just between 1.75 millimeters and 3 millimeters and comes in spools between half a kilogram and two kilograms. These thermoplastics cool very quickly. Once all of the slices are squirted into place, the print is removed from the bed and the nozzle cools off. Filament comes in a number of colors and styles. For example, wood fibers can be added to filament to get a wood-grained finish. Metal can be added to make prints appear metallic and be part metal.  Printing isn't foolproof, though. Filament often gets jammed or the spool gets stuck, usually when something goes wrong. Filament also needs to be stored in a temperature and moisture controlled location or it can cause jobs to fail. Sometimes the software used to slice the .stl file has an incorrect setting, like the wrong size of filament. But in general, 3D printing using the FDM format is pretty straight forward these days. Yet this is technology that should have moved faster in terms of adoption. The past 10 years have seen more progress than the previous ten though. Primarily due to the maker community. Enter the Makers The FDM patent expired in 2009. In 2005, a few years before the FDM patent expired, Dr. Adrian Bowyer started a project to bring inexpensive 3D printers to labs and homes around the world. That project evolved into what we now call the Replicating Rapid Prototyper, or RepRap for short.  RepRap evolved into an open source concept to create self-replicating 3D printers and by 2008, the Darwin printer was the first printer to use RepRap. As a community started to form, more collaborators designed more parts. Some were custom parts to improve the performance of the printer, or replicate the printer to become other printers. Others held the computing mechanisms in place. Some even wrote code to make the printer able to boot off a MicroSD card and then added a network interface so files could be uploaded to the printer wirelessly. There was a rising tide of printers. People were reading about what 3D printers were doing and wanted to get involved. There was also a movement in the maker space, so people wanted to make things themselves. There was a craft to it. Part of that was wanting to share. Whether that was at a maker space or share ideas and plans and code online. Like the RepRap team had done.  One of those maker spaces was NYC Resistor, founded in 2007. Bre Pettis, Adam Mayer, and Zach Smith from there took some of the work from the RepRap project and had ideas for a few new projects they'd like to start. The first was a site that Zach Smith created called Thingiverse. Bre Pettis joined in and they allowed users to upload .stl files and trade them. It's now the largest site for trading hundreds of thousands of designs to print about anything imaginable. Well, everything except guns. Then comes 2009. The patent for FDM expires and a number of companies respond by launching printers and services. Almost overnight the price for a 3D printer fell from $10,000 to $1,000 and continued to drop. Shapeways had created a company the year before to take files and print them for people. Pettis, Mayer, and Smith from NYC Resistor also founded a company called MakerBot Industries. They'd already made a little bit of a name for themselves with the Thingiverse site. They knew the mind of a maker. And so they decided to make a kit to sell to people that wanted to build their own printers. They sold 3,500 kits in the first couple of years. They had a good brand and knew the people who bought these kinds of devices. So they took venture funding to grow the company. So they raised $10M in funding in 2011 in a round led by the Foundry Group, along with Bezos, RRE, 500 Startups and a few others. They hired and grew fast. Smith left in 2012 and they were getting closer and closer with Stratasys, who if we remember were the original creators of FDM. So Stratasys ended up buying out the company in 2013 for $403M. Sales were disappointing so there was a changeup in leadership, with Pettis leaving and they've become much more about additive manufacturing than a company built to appeal to makers. And yet the opportunity to own that market is still there. This was also an era of Kickstarter campaigns. Plenty of 3D printing companies launched through kickstarter including some to take PLA (a biodegradable filament) and ABS materials to the next level. The ExtrusionBot, the MagicBox, the ProtoPlant, the Protopasta, Mixture, Plybot, Robo3D, Mantis, and so many more.  Meanwhile, 3D printing was in the news. 2011 saw the University of Southhampton design a 3d printed aircraft. Ecologic printing cars, and practically every other car company following suit that they were fabricating prototypes with 3d printers, even full cars that ran. Some on their own, some accidentally when parts are published in .stl files online violating various patents.  Ultimaker was another RepRap company that came out of the early Darwin reviews. Martijn Elserman, Erik de Bruin, and Siert Wijnia who couldn't get the Darwin to work so they designed a new printer and took it to market. After a few iterations, they came up with the Ultimaker 2 and have since been growing and releasing new printers  A few years later, a team of Chinese makers, Jack Chen, Huilin Liu, Jingke Tang, Danjun Ao, and Dr. Shengui Chen took the RepRap designs and started a company to manufacturing (Do It Yourself) kits called Creality. They have maintained the open source manifesto of 3D printing that they inherited from RepRap and developed version after version, even raising over $33M to develop the Ender6 on Kickstarter in 2018, then building a new factory and now have the capacity to ship well over half a million printers a year. The future of 3D Printing We can now buy 3D printing pens, over 170 3D Printer manufacturers including 3D systems, Stratasys, and Ceality but also down-market solutions like Fusion3, Formlabs, Desktop Metal, Prusa, and Voxel8. There's also a RecycleBot concept and additional patents expiring every year.  There is little doubt that at some point, instead of driving to Home Depot to get screws or basic parts, we'll print them. Need a new auger for the snow blower? Just print it. Cover on the weed eater break?  Print it. Need a dracolich mini for the next Dungeons and Dragons game? Print it. Need a new pinky toe. OK, maybe that's a bit far. Or is it? In 2015, Swedish Cellink releases bio-ink made from seaweed and algae, which could be used to print cartilage and later released the INKREDIBLE 3D printer for bio printing. The market in 2020 was valued at $13.78 billion with 2.1 million printers shipped. That's expected to grow at a compound annual growth rate of 21% for the next few years. But a lot of that is healthcare, automotive, aerospace, and prototyping still. Apple made the personal computer simple and elegant. But no Apple has emerged for 3D printing. Instead it still feels like the Apple II era, where there are 3D printers in a lot of schools and many offer classes on generating files and printing.  3D printers are certainly great for prototypers and additive manufacturing. They're great for hobbyists, which we call makers these days. But there will be a time when there is a printer in most homes, the way we have electricity, televisions, phones, and other critical technologies. But there are a few things that have to happen first, to make the printers easier to use. These include: Every printer needs to automatically level. This is one of the biggest reasons jobs fail and new users become frustrated. More consistent filament. Spools are still all just a little bit different. Printers need sensors in the extruder that detect if a job should be paused because the filament is jammed, humid, or caught. This adds the ability to potentially resume print jobs and waste less filament and time. Automated slicing in the printer microcode that senses the filament and slices. Better system boards (e.g. there's a tool called Klipper that moves the math from the system board on a Creality Ender 3 to a Raspberry Pi). Cameras on the printer should watch jobs and use TinyML to determine if they are going to fail as early as possible to halt printing so it can start over. Most of the consumer solutions don't have great support. Maybe users are limited to calling a place in a foreign country where support hours don't make sense for them or maybe the products are just too much of a hacker/maker/hobbyist solution. There needs to be an option for color printing. This could be a really expensive sprayer or ink like inkjet printers use at first We love to paint minis we make for Dungeons and Dragons but could get amazingly accurate resolutions to create amazing things with automated coloring.  For a real game changer, the RecycleBot concept needs to be merged with the printer. Imagine if we dropped our plastics into a recycling bin that 3D printers of the world used to create filament. This would help reduce the amount of plastics used in the world in general. And when combined with less moving around of cheap plastic goods that could be printed at home, this also means less energy consumed by transporting goods. The 3D printing technology is still a generation or two away from getting truly mass-marketed. Most hobbyists don't necessarily think of building an elegant, easy-to-use solution because they are so experienced it's hard to understand what the barriers of entry are for any old person. But the company who finally manages to crack that nut might just be the next Apple, Microsoft, or Google of the world.

Coming from the world of gaming, Lars Brubaker started MatterHackers to take part in the 3D printing revolution. Due to his background, he has good war stories: trying to find filament when no one was selling it, except a single individual in New Zealand, or seeking out customer service on some of the first consumer 3D printers. Lars also tells us about building companies: what kind of values, metrics, and strategies  you have to do in order to be successful. By being close to your customers and understanding them, Lars thinks that you can see which way the wind is blowing. MatterHackers´ journey is remarkable from a distributor in the RepRap days to a seller of much more expensive machines and, now, a supplier to the U.S. government.

This week we are joined by Peter Solomon, an amazing designer and FOUNDER of Wham Bam Systems, a 3D Printer accessory company most famous for their Flexible Build Systems and the MUTANT tool changing set up! Peter is going to talk all about his life, starting Wham Bam, and even show us around their NEW FACILITY! Below is Peter's bio and links to Wham Bam! https://whambamsystems.com/ Use code "Musketeers" for 10% off!!! Peter Solomon is an acclaimed industrial designer, problem solver, and entrepreneur. Peter did his undergraduate degree in industrial design at Pratt, NY in the 1980s, worked for a period there after in NY, San Francisco and Los Angeles. Peter's journey as a designer began before the true adoption of computers and 3D programs, and he was active in their implementation and the advent of 3D printers from the beginning. As printers became more and more accessible Peter ran labs of multiple machines, each over $200k, and in 2014 bought a few more consumer facing machines for less than $10k each. Peter participated in testing new printer technology, working with 3D software firms on beta versions and improvements, and continually contributed to forums with his knowledge, advice and upgrades for various machines. When the advent of the RepRap movement provided the community as well as Chinese manufacturer with inexpensive solutions to creating machines, the market shifted dramatically. The forums began to have discussions held by hobbyists and beginners rather than prototypers, designers, and engineers. Peter bought one then two, three Creality FDM printers and was blown away by the low price but great quality of prints with a bit of tuning and upgrades, and began making and sharing his own. In 2017 he began working on a way to have better adhesion but remove prints easier, and sharing his results with the community provoked many requests to offer the complete product instead of the plans. In 2018 Peter together with his Asian Production Partner Steven, and Marketing Director Melinda decided to open Wham Bam, and ran a kick starter campaign with 6 sizes of Flexible Build System. Today Wham Bam is going on its 4th year, has moved into a larger space with warehousing, has multiple distributors all over the world and has over 300 SKUS. During COVID's early spread Peter also founded Egis Viso to make superior face-shields and get them out to healthcare professionals and front liners. in 2020 he also established an association for professionals in Rapid Manufacture.

Tom finished his VORON 2.4 build live streaming marathon and talks about his experience and the choices he made, for example using a DUET 3 with Reprap firmware instead of the usually used Klipper configuration. Stefan shows the latest Make magazine Germany in which this Podcast got featured. Both discuss the “Jugend Forscht” winning entry where ultrasonic modules are used to heat and disperse resin for better prints. Then there is a talk about the suspension of the Torshn Kickstarter and a still on-going crowd funding campaign on a 3D printed bike helmet. The questions cover topics on how to make 3D prints watertight, Siraya Tech resin availability in Europe and RRF on other boards besides Duet.

IC3D first began during the "boom" of 3D printing that started in 2012. Patents had expired and the RepRap project allowed people all over the world to start using 3D printers. However, filament was hard to find and generally low-quality. IC3D started extruding and selling their own filament in Columbus, Ohio. Today, they offer filament, 3D printing services, and large-format 3D printers. Click here: https://tinyurl.com/IC3D-3DPA and use promo code "3DPrintAuthority15" to receive 15% off your filament order at IC3D. An entrepreneur at heart, Matt has been the COO (Chief Operations Officer) at IC3D since 2014. He leads operations, print service job quoting and customer enjoyment at IC3D lending his expertise in engineering and 3D printing to prosumers worldwide. Before graduating with his masters degree in mechanical engineering from The Ohio State University, Matt started a 3D printing service company in 2013 to design and make items from reproduction car parts, to tooling for carbon fiber part production. An automotive engineer by trade, Matt has been involved in many projects including the development of hybrid vehicles, off road vehicles, and the Chevy Sonic RallyCross car, which made its debut at the 2013 X-games. These experiences have allowed him to channel his engineering passion into disrupting manufacturing techniques with large format 3D printing. Nowadays, Matt's focus is sustainability and pushing the plastics industry into a circular economy. Building partnerships with high-volume plastics producers will allow IC3D to reclaim waste and re-circulate material. Matt spends much of his time scheming about empowering everyday people with progressive technology. His dream within the next year is to create pellets from recycled plastics that can be repurposed into new parts for individuals and companies alike.

A história e a trajetória das impressoras FDM da Stratasys, pai e mãe das impressoras RepRap e de desktop de todo o mundo

On this this episode of Additive Insight, TCT Deputy Group Editor Laura Griffiths speaks to Xavier Martínez Faneca, CEO of Barcelona-based 3D printing company BCN3D. BCN3D is manufacturer of polymer extrusion-based desktop 3D printers, which spun out of the Polytechnic university of Catalonia. From automotive to fashion, the company is said to have an install base of around 5,000 machines employed by a wide range of professional and industrial users, and just recently raised €2.8 million in funding to expand its 3D printing hardware and materials portfolio. On this episode Faneca discusses BCN3D's origins in the RepRap movement, its unique IDEX (Independent Dual Extruder) technology and the latest iterations of its Sigma and Epsilon family of 3D printers. This episode is brought to you in association with TCT 3Sixty, the event for 3D printing and additive manufacturing intelligence.

Panelists Eric Berry | Justin Dorfman | Richard Littauer Guest Amanda Brock OpenUK Andrew Katz Orcro Show Notes Hello and welcome to Sustain! Today, we have two special guests from the UK, Amanda Brock and Andrew Katz. Amanda is CEO of the UK body for “open” and OpenUK. Andrew is a lawyer working for a small boutique consulting firm that does open source things. We are discussing contact tracing apps and how they are going. We will find out how Amanda built her team when she was at Canonical. Then we will find out all about OpenUK and OpenUK KidsCamp, and the MINI-MU Glove, which is the coolest things ever! Andrew tells us about open hardware, Open-Silicon, open source licensing, and research he is doing. Download this episode now to learn more! [00:01:06] Alex and Amanda tell us how they know each other and what they are working on. [00:02:30] Since Alex and Amanda are both involved in contact tracing apps, which are coming out right now, they talk a bit about the British effort there and how it’s going. [00:06:38] Justin is curious and wants Amanda to tell us when working at Canonical, the day to day for a lawyer just coming into the organization that was shaking things up in the Linux world and just the open source world, what did she do and how did she build the team. She also talks about the Dell deal when Dell started putting Ubuntu on their laptops for context, which was the first thing she worked on. [00:10:54] Andrew turns the table and asks Amanda how it felt and how did you adapt to dealing with changes in negotiation dynamic changes. Richard asks how has that fueled your work with OpenUK and how do you feel that experience has allowed you to go forth and work there and what are your goals? [00:15:24] Amanda talks about what OpenUK does and she tells us more about OpenUK KidsCamp, which their goal is have it running by 2022. She talks about the “MINI-MU Glove.” What a cool thing! (kit linked below.) [00:22:41] Justin goes back to Canonical and wants to know what went wrong with Ubuntu phone. Andrew tells us how his experience has been working with open hardware. Andrew also lets us know of some other open hardware projects other than what he’s working on. He explains what Open-Silicon is. [00:30:17] Eric wants to know what challenges Andrew is seeing with open source licensing and does he feel there is a certain amount of pressure or necessity for you to push and determine these different licenses that should exist. Also, what’s the goal of the research he’s been doing. [00:35:41] Richard is amazed by the level of hardware hack that seems to go on in Britain, like RepRap, and he asks Andrew if he has any thoughts on why they are further along. [00:39:27] Amanda tells us where we could find them and where can we read about the work that’s going on and she tells us about her book. [00:45:40] Eric has one last question for Amanda and Alex and asks them why do they think that these countries are not wanting to open source their research and their findings in order to help us reach our goal of everybody can go back to school and work? They tell us their thoughts on this. Spotlight [00:42:18] Justin’s spotlight is Sia.tech by NebulousLabs, [00:42:43] Eric’s spotlight is our amazing editors for this podcast at Peachtree Sound. ☺ [00:44:01] Richard’s spotlight is strangeparts.com. [00:44:35] Andrew’s spotlight is CERN Open Hardware Licence. [00:45:07] Amanda’s has two spotlights: OpenRan and LibreOffice. Quotes [00:31:56] The most interesting part of the research has been talking to people, you know, who are well understood, who are very prominent in this area, and understanding their different viewpoints.” [00:37:20] “With Brexit, it made me sort of focus a bit more on what was happening.” Links Amanda Brock Twitter  (https://twitter.com/amandabrockuk?lang=en) OpenUK Twitter (https://twitter.com/openuk_uk?lang=en) OpenUK Linkedin (https://www.linkedin.com/company/openukopentechnology) OpenUK (https://openuk.uk/) OpenUK GitHub (https://github.com/OpenUK) Andrew Katz Twitter (https://twitter.com/andrewjskatz?lang=en) Andrew Katz Linkedin (https://www.linkedin.com/in/andrewjskatz/) Canonical (https://canonical.com/) OpenUK Kids Camp (https://openuk.uk/openkidscamp/) MINI.MU Glove Kit (https://shop.pimoroni.com/products/mini-mu-glove-kit?variant=21240082497619) RepRap (https://reprap.org/wiki/RepRap) Sia.tech (https://sia.tech/) Peachtree Sound (https://www.peachtreesound.com/) Strange Parts (https://strangeparts.com/) CERN Open Hardware Licence (https://ohwr.org/welcome) OpenRAN (https://telecominfraproject.com/openran/) LibreOffice article (https://www.theregister.com/2020/07/16/libreoffice_ecosystem_beyond_utterly_broken/) Open Tech Reponse (https://opentechresponse.com/) Moorcrofts Corporate Law-“CERN Open Hardware Licence 2.0 Andrew Katz presents, ahead of the official release.” (https://moorcrofts.com/cern-open-hardware-licence-2-0-andrew-katz-presents-ahead-of-the-official-release/) Free and Open Source Software: Policy, Law, and Practice (second edition to be released August 2020) (https://global.oup.com/academic/product/free-and-open-source-software-9780199680498?cc=gb&lang=en&) Credits Produced by Justin Dorfman (https://www.justindorfman.com/) Rebase.fm (https://rebase.fm/) Edited by Paul M.

In the fifth #NFFStories podcast, Adrian Bowyer, Founder and Director of RepRap Ltd., develops his experience as academic body member of the 2019 Robotics Atelier and his seminar presented during the week-long event on the reasoning behind technology copying itself. Bowyer's project consists in creating humanity’s first general purpose self-replicating manufacturing machine, and his company researches self-replicating open-source 3D printing. RepRap printer takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of the printer are made from plastic and the printer prints those parts, RepRap self replicates by making a kit of itself. RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. #NFFStories is a new series of podcasts produced by the Norman Foster Foundation that aims to empower our community to make positive change. A new platform for people around the world to share and hear inspirational stories and ideas that are going to shape the future.

Levi declares his analogist superiority and talks about 3d printing… all to Amy's amusement. Then, the kids talk about Star Wars characters, etc.

Happy Friday, my friends! We're back with the second episode of the Indiana Geeking Podcast, the podcast where we focus on Hoosier-based creators and events! This month, Lizz and I took a trip to one of the top 3D Printing events, the Midwest RepRap Festival. Held in Goshen, it brought in makers from across the world to show off their work, their machines, and eat tacos. As we were looking around, and preparing to start our own journey into 3D printing (more on that next week), we found some folks from here in Indiana that we wanted to talk Hoosier business with. Luckily, I had the trusty old Zoom H1 with me, so I was able to get some interviews with some folks in northern Indiana who make 3D Printers, filament, and use all of this to make their own props and costumes! So, without further ado, join me as I give you some top events for the month of April, then jump into a series of short interviews with some of the local folks tabling at MRRF! Don't worry, this one's only about 45 minutes long! NOTE: You can find the Facebook Photo Album with the photos we took at this link.

Tom and Stefan talk about their experiences in annealing PLA prints and discuss the recent change in Fusion 360's pricing model. Recently a paper on a so called "3D printer fingerpint" was released that claims to be able to track prints back the printer they were made on, with stunning accuracy, so they talk about how realistic this could be and what the implications of such a method might be. Tom recently came back home from his roadtrip all over Europe where he filmed bits for his RepRap documentary and talks about the new high temperature products he has seen at E3Ds headquarter. Finally Stefan recently built his DIY filament extruder and talks about his first experience in making his own filament at home.

As passwords já fazem parte do nosso dia a dia. Para tudo online é preciso uma senha. Portanto guardar as password num sitio seguro e abrir quando forem necessárias é, na minha opinião, a melhor opção hoje em dia e por isso numa tentativa de melhorar a segurança e de ao mesmo tempo facilitar a vida aos utilizadores, surgem os gestores de passwords. Mas existem muitos gestores de passwords e por isso algumas questões que são importantes fazermos são: Será que vale a pena usar? Se sim, Qual escolher? São estas questões principais que vou responde. _________________ Não se esqueçam de apoiar o projeto por deixar o vosso feedback directamente no soundcloud, Itunes ou para podcast@linuxtech.pt Se quiseres apoiar monetariamente o projeto: Patreon: www.patreon.com/linuxtech _________________ Patrocinios: www.reprap.pt/ www.emprego.rumos.pt/ www.facebook.com/pontas.gama ________________________________ Redes Sociais: Facebook: www.facebook.com/linuxtechpt Youtube: www.youtube.com/c/linuxtechpt1 Twitter: twitter.com/Linuxtechpt Google+: plus.google.com/+linuxtechpt1 Soundcloud: @linuxtech RSS FEED: linuxtech.libsyn.com/rss Ítunes: itunes.apple.com/pt/podcast/linux…d1262817926?mt=2 ________________________________ Musicas tocadas durante o episódio: Nameless: The Hackers RPG Soundtrack by BoxCat Games (itunes.apple.com/us/developer/box…-llc/id519986951) is licensed under a Creative Commons Attribution License (creativecommons.org/licenses/by/3.0/) @lakeyinspired ____________________ Dashlane (www.dashlane.com/) Lastpass (www.lastpass.com/pt) Keeper (keepersecurity.com/pt_PT/) 1password (1password.com/) Bitwarden (bitwarden.com/) Sticky Password (www.stickypassword.com/) Keepass / Keepassx / Keepassxc (keepassxc.org/) Enpass (www.enpass.io/)

Hey everyone, welcome back to Bionic Bug podcast! You’re listening to episode 16. This is your host Natasha Bajema, fiction author, futurist, and national security expert. I’m recording this episode on August 5, 2018. First off, I have a personal update. Next weekend, I’m headed to the Writer’s Policy Academy in Green Bay Wisconsin. I’ll be participating in two days of an interactive and educational hands-on experience led by police detectives and officers and designed for writers to enhance their understanding of all aspects of law enforcement, firefighting, EMS, and forensics. I’m currently signed up for hands-on sessions on high-speed pursuits, a car set ablaze and door entry/breaching among other things. Stay tuned for my read out in a few weeks. Let’s talk tech news. It’s been an “exciting” week for emerging technologies and their potential risks. 3D printing made the headlines across the country this week, even making it onto the daily show with Trevor Noah. In truth, this is a threat that has been building for more than six years that has largely remained off the public’s radar. This week, a legal battle broke out with 19 states pitted against the State Department and Defense Distributed. In 2012, Cody Wilson, a second year law student at the University of Texas, and his friends got together and named themselves “Defense Distributed” and launched the “Wiki Weapon Project.” The idea was to create a gun that anyone could easily make at home. They used a crowdfunding website to raise funds to develop a 3D printed plastic gun that can be printed by a low-cost, open source 3D printer known as the RepRap. The group successfully produced a plastic gun capable of firing a .22 caliber bullet in 2013. The gun is called “The Liberator”. Cody Wilson and his friends uploaded the blueprint online. The design has two metal components the firing pin and a small piece of steel. The steel part is designed to make the gun detectable with a metal detector. The U.S. Undetectable Firearms Act prohibits weapons that don't set off a metal detector. The design was downloaded 100,000 times in just two days before the State Department stepped in, demanding the removal of the blueprint from the website under the International Traffic in Arms Regulations (ITAR), which governs the export of munitions. Wilson took down the blueprint, but it soon became available on disreputable file-sharing websites such as The Pirates Bay and on the Dark Web. Since this development, many more gun designs have been made available online. So why now? In 2015, Cody Wilson and Defense Distributed filed a law suit against the State Department, claiming his First Amendment rights were being infringed. The State Department settled with Wilson last month, allowing Defense Distributed to release the designs online for downloading. On Tuesday, a federal judge in Seattle granted a temporary restraining order to stop the posting of blueprints that would have legally allowed Americans to make 3D-printed guns in their own homes. Let’s unpack the issues. These guns are called “ghost guns” because they have no serial numbers, untraceable, undetectable They are homemade. Anyone with access to the Internet can download the blueprint and then print the parts using a cheap 3D printer. These guns are not entirely undetectable. “The TSA Has Found 3D-Printed Guns at Airport Checkpoints 4 Times Since 2016” The designs include a small metal part that can be detected by metal detectors. It remains illegal to develop guns that cannot be detected. I’m not sure if I understand why everyone is freaking out about this new development. We already have a gun accessibility problem in this country. Practically anyone can get access to weapons in the U.S., even semi-automatic weapons, including criminals. Plastic guns are not nearly as effective and run the risk of exploding after multiple shots.

Acho que todos já passaram por isso e acredito que alguns dos que ouvem este podcast continuam a passar que é, a busca eterna da “distribuição ideal”. Depois de alguns anos a usar várias distribuições, chego a conclusão que a busca da distribuição ideal, não passa de utopia. Vão ficar a perceber o porquê, juntamente com noticias e artigos recentes.

In this episode Scott talks with guest host Chris Warkocki about 3D printing in a lot more detail than we have in past episodes. He as been intensely tinkering with 3D printing and currently has 4 printers. We talk about prusa machines such as the original, i3 MK2S, and I3MK3. The biggest advancement these days comes in the form of reliability. The I3MK3, for example, has a magnetic flexible steel bed, 256 micro-stepping Trinamic drivers, and the ability to sense if filament is almost out. Technology is advancing rapidly thanks to the global reprap community of tinkers that share knowledge. Chris has been printing figures and terrain for D&D campaigns as well as various other printing projects. He does a lot of modding and adjustment to his printers to get the best quality possible such as using modified Ikea Lack coffee tables as 3d printer housings. This episode is a 3D printing extravaganza of information!

En el artículo de esta semana traigo una entrevista a un invitado muy especial. El es Ingeniero Informático y Técnico Superior de Desarrollo de Software. Lleva muchos años dedicado al mundo del desarrollo de software y otros tantos defendiendo, divulgando y compartiendo la cultura libre y el movimiento Maker.Uno de los primeros socios en la asociación Hispalinux. Moderador del foro de Arduino y miembro de Clone Wars y RepRap. Lo hemos podido ver dando decenas de charlas por toda España transmitiendo la cultura libre, la impresión 3D y el ecosistema de Arduino.Ha colaborado en multitud de proyectos ayudando, compartiendo y difundiendo la idea detrás de cada uno de ellos. Siempre ha estado en primera línea, aunque él no quisiera.Como bien dicen sus amigos más cercanos, es una persona humilde y es el pegamento social que nos une a todos los Makers y nos saca de nuestros talleres y oficinas.Desde la lejanía lo vemos como un tío serio, duro y curtido en la vida. Sin embargo cuando te acercas a él sigue siendo grande pero desprende energía positiva, vida, humor y sobre todo muchas muchas palabras.El aire místico que envuelve a sus charlas dejan entrever que hay esperanza, que todos somos especiales y que las cosas se pueden hacer de otra manera.A veces me pregunto si él se unió al movimiento Maker o fue el movimiento Maker quien reclutó a Juan Manuel Amuedo en su cruzada por las tecnologías libres.Todos le conocemos por su seudónimo, Coleóptero, Cole para todos los Makers.Más información en https://programarfacil.com/podcast/historia-movimiento-maker-colepower/

Desktop 3D printing is where it is today because of the corporate asset value of intellectual property laws and regulations. Looking back at how a dislike of patents came about due to the open-source RepRap movement and why this ideology needs to take a backseat if the industry wants to move forward even further.

Hoy tenemos el enorme placer de tener con nosotros a Juan González Gómez, más conocido como Obijuan. Ingeniero Superior de Telecomunicaciones y Doctor en robótica con mención europea. Se define cómo un hacker y un maker, apasionado de la robótica y defensor del hardware y software libre. Fundador de Clone Wars y FPGAs Wars.Obijuan es un referente en España en la impresión 3D y ejemplo a seguir por todos. Además de sus capacidades técnicas e intelectuales, destaca su gran humanidad y el objetivo de acercar a todo el mundo el software libre.Sus orígenesComo tantos otros de nosotros, Obijuan disfruto de esa maravillosa época donde los ordenadores entraron en nuestras casas, la era pre-internet. Desde muy pequeño ya era un apasionado de la robótica, quizás debido al éxito de la famosa serie Mazinger Z, que todos disfrutamos en nuestra niñez.Pero en aquella época había muy pocos recursos relacionados con los robots. Lo máximo que conseguía eran libros donde se explicaban miles de fórmulas matemáticas, pero ninguno de cómo construir su propio robot. Como él dice, era una frustración.No estaba todo perdido. Suplió esa ausencia de material para construir un robot con los ordenadores y decidió aprender a programar por el interés que despertaba en él y la facilidad. Con los ordenadores de la década de los años 80, solo podíamos hacer dos cosas, programar y jugar. Precisamente esto nos hizo introducirnos al mundo de la programación a muchos de nosotros.Todavía recuerdo con añoranza la revista Micro Hobby donde, venían trozos de código de programas que nos esforzábamos en copiar con sumo cuidado para poder ejecutarlos.MicrohobbyLos robots modularesUna vez terminada la Ingeniería de Telecomunicaciones, decidió seguir estudiando y hacer el Doctorado. Como no podía ser de otra manera, eligió la robótica para su tesis, más concreto los robots modulares.Los robots modulares consisten en hacer unos módulos lo más simples posibles y crear robots a base de unir estos módulos. Dependiendo de su conexión, tienes diferentes topologías de robots. El robot más sencillo de hacer con esta técnica es un robot gusano o serpiente.Justo en esta época fue cuando empezó a darse cuenta de lo importante que es tener acceso a toda la información. Según iba desarrollando su tesis doctoral, vio que tenía acceso a mucho material teórico relacionado con el tema, algoritmos y toda la lógica interna de un robot, pero no tenía acceso ni los planos ni al software que le permitieran construir los módulos.En ese momento decidió crearse sus propios módulos pero no fue fácil. Debido a su formación, tenía conocimientos electrónicos y de programación, pero de mecánica no sabía nada. Con mucho esfuerzo consiguió fabricar con una cortadora láser, los primeros módulos.Pero no solo eso, los compartió con toda la comunidad para que el siguiente investigador o cualquier persona, pudiera replicarlos y mejorarlos.Módulo Y1Planos y documentaciónImpresión 3DObijuan conocía la impresión 3D desde hacía bastante tiempo, los orígenes de esta técnica se remontan a los años 80 y solo para el sector industriual. Pero realmente fue consciente del potencial que tenían cuando pudo presenciar y ver con sus propios ojos las piezas que se podían crear.En el año 2005, Adrian Bowyer, publicó un blog en el que empezaba a decir que quería hacer una impresora 3D que se pudiera replicar. Esos fueron los inicios de RepRap.Primera reprapHasta el año 2008, no consiguieron hacer la primera auto réplica de una impresora 3D. Hito histórico que se recordará a lo largo del tiempo. A finales de ese mismo año, Adrian Bowyer fue a dar una charla al Medialab-Prado. Obijuan asistió y, aunque le sorprendió la poca cantidad de gente, quedó fascinado al poder comprobar físicamente lo que se podía hacer con una impresora 3D. Pudo sentir como sería el futuro.A partir de aquí solo tuvo que conectar los puntos. En el Medialab-Prado también conoció a Zach Smith fundador de Makerbot. Todavía no estaban disponibles las impresoras por las cuales hicieron famoso a Zach, faltaban unos meses. En el momento que salieron, Obijuan se hizo con una de ellas, la impresora Makerbot número 8 de todo el mundo.

While many people involved in the RepRap movement, and the modern desktop 3D printing industry, think that Intellectual Property has been holding the industry back from growing to its full potential, Tom & Tracy discuss how Intellectual Property plays an important role in corporate asset value, and is actually responsible for making desktop 3D printing what it is today.

Wir waren im schönen Schönau (sorry für die Tautologie) bei Kremsmünster in Oberösterreich bei Benjamin Krux zu Gast, der uns freundlicherweise eine kleine Einführung in die Welt des 3D druckens gegeben hat. Für manche von uns schon Begleiter im täglichen Leben (Max arbeitet als Doktorand am Institut für Verarbeitung von Verbundwerkstoffen) erfahren wir was die Knackpunkte bei 3D Druck sind, wo die Technik derzeit steht, und wo der Weg hingehen könnte. In der Mittelschule in Vorchdorf hat Benjamin kürzlich das Pilotprojekt einer 3D Druck Klasse gestartet um die nächste Generation schon jetzt mit dem Thema vertraut zu machen. Eine spannende Episode mit wie wir hoffen durchgehendem "Roten Filament".

Cet épisode est un peu spécial puisqu'il s'agit d'un crossover entre podcast science et vie artificielle. Vous le retrouverez donc aussi en tant qu'épisode 73 de podcast science. Il est aussi particulièrement long (1h30). J'ai assez mal évalué le temps nécessaire à l'exposé de mon dossier. Vous pouvez me retrouver sur twitter (https://twitter.com/Xilrian) et vous abonner sur : notre flux RSS (http://feeds.feedburner.com/vieartificielle), iTunes (http://itunes.apple.com/fr/podcast/vie-artificielle/id471402436), Youtube (http://www.youtube.com/channel/UCuPLI-CCXwPeCuwsQQUcN-Q/videos) et soundcloud (https://soundcloud.com/xilrian). Le dossier Quelques définitions : L’idée directrice du transhumanisme est que nous approchons d’un tournant où la science et la technique vont rendre possible la création d’un homme pas – ou moins – soumis au vieillissement, et qui aura des capacités intellectuelles et physiques supérieures. Un post-humain ! En découle une volonté de changer l’homme. Pour les transhumanistes, cet objectif sera rendu possible par les progrès de la technique et aboutira au changement de la nature humaine. Derrière le post humanisme se cache une grande confiance en la science et une croyance en l'existence d’un progrès. Et si le terme n’était pas connoté négativement je dirais que le post humanisme est une forme de scientisme. Au passage vous vous demandez sûrement s’il faut faire une distinction entre “trans” et “post” humanisme. Il me semble que dans le monde anglo-saxon le terme transhumanisme est beaucoup plus utilisé. Il me semble aussi qu’il n’y a pas de définition universellement admise faisant une distinction claire entre ces deux concepts. Mais le terme transhumanisme insiste naturellement plus sur la transition c’est à dire l’amélioration de l’homme actuel. Tandis que le terme post humanisme peut faire référence à un posthumain ayant éventuellement quitté son statut d’humain. La singularité est une idée, attribuée à John Von Neumann un brillant savant américain des années 40-50 dont les auditeurs de vie artificielle ont déjà entendu parler. JVN est l’un des pères de l’informatique avec Alan Turing et c’est aussi le créateur du concept de singularité technologique. Le concept de la singularité est qu’il y a une «accélération accélérée» du progrès technologique humain et que, si l’on représente ce progrès par une courbe, on approche d’une sorte de tangente verticale. Pour les partisans de la singularité, quand on passera ce point, cette tangente, la singularité, les progrès technologique seront si importants que l’on aboutira à une sorte d’explosion de l’intelligence dont les conséquences sont quasi impossibles à imaginer. La singularité est souvent présentée comme reliée à l’informatique : aux lois de Moore et à des Intelligence Artificielles ou des machine capables de créer des versions améliorées d’elles-mêmes. Ce qui est dans la droite lignée des travaux de John Von Neumann. Il est aisé d’imaginer que la singularité technologique puisse être conçue comme un moyen de créer des posthumains. L'extropie, que l'on va aussi retrouver chez certains transhumanistes est l’idée que l’on soit capable, par la technique d’inverser l’entropie de l’univers. Ce qui semble pour le moins utopique. Rapide historique Les gens qui présentent le transhumanisme signalent généralement, il me semble à juste titre… Qu’il s’inscrit dans la droite lignée de traditions scientifico-mystiques bien plus anciennes qui, elles aussi, cherchaient à découvrir les moyens d’accéder à l’immortalité. On peut citer la tradition gnostique du Christianisme, les recherches des alchimistes, certaines religions orientales… La légende de Gilgamesh. Héro sumérien cherchant à acquérir l’immortalité est aussi très fréquemment citée. Plus récemment le transhumanisme est aussi un descendant de l’humanisme et des lumières dans le sens où il se conçoit comme étant une idéologie fondamentalement rationnelle. Et qu’il met l’amélioration de la vie humaine au centre de son dispositif idéologique. Le terme transhumanisme apparaît à la fin des années 50. Mais le transhumanisme tel qu’on le connaît aujourd’hui ne se structure en organisation que dans les années 90 sur des idées provenant des 60 à 80 comme la vague hippie. Ou des idées comme la sémantique générale qui postule qu’on peut changer l’homme, l’améliorer, en changeant le langage. On retrouve dans les mouvements transhumanistes les influences de trois idéologies qui s’entrecroisent : une gauche humaniste, un libertarianisme individualiste et un mouvement hippie en quête de sens… En revenant un petit peu sur le mouvement hippie je vais vous parler de Timothy Leary qui représente assez bien l’excroissance technophile de ce mouvement. Il est connu pour avoir été l’un des prophètes du LSD. Mais aussi un scientifique reconnu pendant une partie de sa vie. Il développa peu avant sa mort un projet prônant l’augmentation de l'espérance de vie ainsi que l'extension de l’intelligence humaine, le tout associé à de la conquête spatiale. Trois thématiques qu’il est à mon sens cohérent d’associer et que l’on retrouvera dans le mouvement transhumaniste. Les idées qui intéressent les transhumanistes sont souvent à la frontière de la science. Leurs idées ne sont pas franchement dans les pseudosciences, mais elles restent souvent assez marginales. L’imagerie transhumaniste provient en grande partie la SF et du cyberpunk. Mais je ne vais pas du tout développer cet aspect dans ce dossier. On peut tout de même citer le neuromancien de William Gibson comme œuvre ayant inspiré le mouvement et Serial Experiments Lain comme exemple d’œuvre inspirée par les idées transhumanistes. Les organisations transhumanistes des années 90 à nos jours : La première organisation transhumaniste à apparaître est l’extropy institute qui est fondée en 1992 et qui a disparu depuis. On retrouve ici, au moins dans le nom choisi pour l’association, un objectif particulièrement ambitieux, voire irréaliste. Par ailleurs, politiquement, l’institute était semble-t-il particulièrement libertarien et sans doute plutôt à droite. L’organisation a disparu en 2007 même si sa mailing-list reste plutôt active. De l’autre côté, avec des ambitions affichées beaucoup plus raisonnable, apparaît en 1998 l'association mondiale de transhumanisme world transumanism association qui s’est depuis renommée humanity+. Elle propose deux définitions complémentaires du transhumanisme : Le mouvement culturel et intellectuel qui affirme qu'il est possible et désirable d'améliorer fondamentalement la condition humaine par l'usage de la raison, en particulier en développant et diffusant largement les techniques visant à éliminer le vieillissement et à améliorer de manière significative les capacités intellectuelles, physiques et psychologiques de l'être humain. L'étude des répercussions, des promesses et des dangers potentiels de techniques qui nous permettront de surpasser des contraintes inhérentes à la nature humaine ainsi que l'étude des problèmes éthiques que soulèvent l'élaboration et l'usage de telles techniques. On voit donc ici que l’association se place non seulement en promoteur de la technique mais aussi comme un lieu de réflexions aux conséquences éthique de l’arrivée d’un post humain. Dans la même lignée peut être encore un peu plus orienté vers le centre gauche si il faut la situer politiquement on trouve aussi une association française qui s’appelle Technoprog'. Enfin à l’opposé, je dis à l’opposé car le monsieur ne me semble pas forcément outre mesure sympathique, il y a la singularity university de Ray Kurzweil. Le projet est en grande partie financé la NASA et par Google et son directeur Larry Page. L’association organise entre autre une Université d’été où les places sont extrêmement prisées. Le projet semble intéressant mais vu d’assez loin j’ai l’impression qu’il est très, trop orienté business et Networking. Ça semble davantage être l’endroit pour trouver comment commercialiser une invention révolutionnaire qu’un rassemblement de chercheurs. Le deuxième point négatif tient pour moi à la personnalité de Ray Kurzweil : Ray se comporte comme un commercial. On a fréquemment l’impression qu’il cherche à vendre quelque chose. Et c’est souvent réellement le cas. L’homme nous vend une singularité que nous allons voir dans quelques année, il se vend lui même comme un génie alors que ses réalisations semblent assez modeste. J’ai lu en partie l’un de ses ouvrages les plus connu Fantastic Voyage, en français serons-nous immortels ? Je m’attendais à me trouver face à un livre de prospective me ventant des technologies qui allaient augmenter notre espérance de vie… Il y a de ça, un tout petit peu mais le livre est surtout un livre de régimes se proposant de nous expliquer comment nous alimenter pour augmenter notre espérance de vie. C’est déjà assez décevant. Mais en plus Kurzweil suggère dans le régime qu’il propose, d’acheter une série de compléments alimentaires, compléments alimentaires vendu par une société… De Kurzweil lui-même. L’homme ressemble un peu à un richissime propriétaire de plusieurs restaurants étoilés qui s'apprêterait à écrire un guide des meilleurs restaurants… On ne peut s'empêcher de trouver ça suspect. Gravite aussi autour de la singularity university des gens comme Craig Venter. Un scientifique ayant grandement contribué au séquençage du génome humain et étant devenu riche suite à la revente de son entreprise. L’homme travaille actuellement sur la biologie de synthèse et a plus ou moins créé la première cellule vivante artificielle. J’ai une citation de lui qui m’avait été retransmise lors de l’ECAL11 (une conférence européenne bisannuelle sur la vie artificielle) mais dont je n’ai pas retrouvé la trace. Elle résume néanmoins assez bien le personnage. Une journaliste l’interroge et lui demande: “Don’t you think you are playing god modifying life like this? And Craig answers: But who said we are playing?” Venter reste quelqu’un d’intéressant. De même, je n’ai rien contre Google, au contraire. Mais l’association Google Venter Kurzweil NASA donne un sentiment un peu mitigé à l’ensemble on sent poindre quelque chose d’assez médiatique, mégalo et business. Il existe au moins une dernière association transhumaniste, dans laquelle est aussi impliqué Kurzweil, le singularity Institute. Les avancées techniques qui pourraient caractériser le post humain Généralement, l’élément avancé est l'espoir dans les technologies convergentes c’est à dire le développement conjoint des nanotechnologies, des bio-technologies et de l’informatique pour changer le monde et l’homme. Les meilleurs exemples et les exemples les plus concrets se retrouvent actuellement dans letraitement du handicap. Je pense par exemple à Oscar Pistorius, cet athlète handicapé qui court aussi vite que les athlètes valides. Difficile de dire dans son cas si ses jambes artificielles lui apportent un avantage ou le handicapent dans sa course. La performance reste comparable à celle des athlètes classiques, mais il semble acquis que les avancées de la techniques permettrons tôt où tard à des athlètes handicapés de courir plus vite que des athlètes valides. iv>Mais d’ailleurs on pourrait aussi affirmer que les acteurs valides consommant des produits dopants sont eux aussi des hommes augmentés. En revenant sur le handicap et les réalisations concrètes, on peut aussi penser à l’artificial retina project qui permet de rendre la vue à certains aveugles. C’est une espèce d’œil artificiel qui cumule un implant au niveau des connexions nerveuse et une caméra branchée sur des lunettes de soleil et qui offre déjà une vision en noir et blanc avec une définition d’environs 200 px sur 200 sur les derniers modèles. Nul doute aussi que le développement de ce genre de dispositif pourrait à terme permettre à des aveugles de voir à des distances supérieures. La cybernétique est très présente dans le mouvement transhumaniste. Il y a aussi par exemple les travaux de Kevin Warwick qui travaille sur la connexion du système nerveux humain à des machines. Si je ne me trompe pas, il a commencé par s’implanter une simple puce qui permettait de le localiser et donc d’effectuer dans son laboratoire quelques interactions sympas mais pas extraordinaires, du type voir les portes s’ouvrir sur son passage ou la lumière s'allumer et s’éteindre. Par la suite, il a réalisé des expériences bien plus impressionnantes. Par exemple après avoir implanté une grille d’électrodes dans un nerf de son bras, il pouvait commander à distance son propre bras via un ordinateur. Il a aussi effectué une «connexion sensorielle» avec sa femme qui s’était implanté une grille d’électrodes similaire. Le monsieur promet que ses recherches pourront déboucher sur de la communication ressemblant à une communication télépathique par ce procédé en 2015… Donc demain. Après, on peut citer les très nombreuses recherches autours du vieillissement cellulaire comme par exemple les travaux très contesté d’Aubrey de Grey qui identifie 7 causes du vieillissement et qui considère que nous sommes proches de les inverser. Dans l’arsenal de solutions envisagées par les transhumanistes on retrouve aussi des modifications génétiques sur l'embryon par exemple pour prévenir une maladie génétique. Pour revenir sur lesnanotechnologies on retrouve l’idée d’un assembleur moléculaire capable de construire de la matière atome par atome. Voire aussi capable de s’autorépliquer. On imagine que de telles machines auraient de multiples utilités potentielles y compris dans le domaine de la médecine. On trouve aussi des idées beaucoup plus fantasques telles que la cryogénisation. Dont un détracteur expliquait que si ressusciter une personne cryogénisée n’était pas impossible, la difficulté serait comparable à la reconstitution d’une vache à partir d’un hamburger. Enfin il y a la question de l’uploading : l’uploading, c’est l’idée qu’on pourra un jour uploader l’esprit humain dans une machine. C’est en quelque sorte la dématérialisation totale de l’essence de notre être. Se transformer en pure information. On est très loin de pouvoir réaliser cet uploading. Mais on arrive déjà à connecter une mémoire électronique à un cerveau de souris. Et certaines personnes envisagent d’utiliser ce genre de techniques pour soigner la maladie d’Alzheimer. Pour terminer un petit peu sur ces réalisations techniques et pour revenir sur terre, on notera aussi que les projets mis en valeur sur les sites de humanity plus ou de la Singularity University tournent autour del’empowerment avec par exemple des plan de RepRap sur humanity plus mais aussi du développement durable de l’humanitaire. Quelques réflexions sur le transhumanisme Une des thématiques qui revient fréquemment est la création de quelque chose d’autonome capable de se répliquer et de s’améliorer c’est la qu’on retrouve des thématiques proche de la vie artificielle et des recherches en intelligence artificielle. J’en profite pour ajouter, pour faire le lien avec le précédent dossier, un mot sur que ce que Susan Blackmore appelle des temes. Ce sont des créatures technologiques auto-réplicatrices évoluant par sélection naturelle. Même si ce mot n’est pas vraiment utilisé par les transhumaniste le concept qu’il couvre est intéressent et recouvre des thématiques et font parti des outils qui intéresse beaucoup les transhumanistes. Pour rester dans le domaine de la sélection naturelle, les mèmes font aussi partie des thématiques mentionnées par les transhumanistes. Il y a derrière cela l’idée que comprendre les mèmes pourrait expliquer nos pensées et donc permettre de s’améliorer. Un peu comme la sémantique générale dont je vous parlais précédemment. Bien évidement, on retrouve une multitude d’autres thématiques telle la convergence homme machine, l’immortalité… On peut aussi se demander si nous ne sommes pas déjà des hommes augmentés; l’homme est caractérisé par l’utilisation d’outils.En quoi est-ce qu’un aveugle avec des yeux bioniques serait plus transhumain qu’un homme normal avec une paire de jumelles? Est-ce l’implant et la modification physique qui nous rend transhumain ? Alors les personnes tatouées ou avec des pacemakers sont déjà des transhumains… L’imprimerie a aussi durablement changé l’homme…Et il semble que la pratique du net modifie grandement notre capacité à lire linéairement. Il n’y a mon sens qu’une différence de degrés entre le marteau et l’implant nous rendant télépathe de Warwick. La question de la différence de nature n’arrive à mon sens qu’avec les modifications génétiques ou l’uploading qui semblent à l’heure actuelle l’un et l’autre assez lointains. Après, le fait que l’on ait affaire à une différence de degrés et que l’on soit dans un processus largement entamé n'empêche pas de réfléchir aux conséquences de ces changements. A mon sens le transhumanisme, c’est essentiellement de la prospective technologique et des réflexions sur les conséquences de ces technologies futures. Le tout accompagné d’un regard globalement optimiste sur ces technologies. C’est un mouvement aussi très tourné vers la liberté individuelle… Il n’est pas question d’imposer mais de proposer ce changement. Initialement, c’est quelque chose qui tient quasiment d’une quête personnelle… Et qu’on retrouve dans le côté livre de régime/manuel de développement personnel du livre de Ray Kurzweil où dans le côté auto-expérimentation de Warwick. Mais on retrouve aussi cela dans la notion d’empowerment et la proximité idéologique avec des mouvements autour des fablab et autres hacklabs. C’est aussi cet aspect très libertarien qui éloigne le projet transhumanisme des dystopies totalitaires, c’est à dire des contre-utopies que sont 1984 d’Orwell et le meilleur des mondes d’Aldous Huxley. D’ailleurs Huxley était proche de Leary et frère du créateur du mot transhumanisme. Il a un peu plus tard écrit un roman l’Ile que je n’ai pas lu pour présenter une utopie technologique positive. La structuration du mouvement en organisation à partir de la fin des années 90 marque une étape importante dans le passage d’un mouvement culturel individualiste à quelque chose d’un peu plus politique porteur d’une idéologie. Un mouvement capable de faire du lobbying. Et il me semble aussi que le petit succès politique du transhumanisme répond à un relatif vide idéologique… La lutte entre pays communistes et monde libéralo-capitaliste semble actuellement dépassé et ce qu’il reste de ces deux idéologies ne fait plus rêver. L'extrémisme religieux revient en force sans doute pour cette même raison mais l'influence des religions sur la société décroît au moins en occident et chez les personnes ayant effectué des études longues (et de mon point de vue c’est une très bonne chose). Le post humanisme fournit une idéologie pour laquelle on peut envisager de militer, on retrouve d’ailleurs fréquemment des encouragements au prosélytisme sur les sites transhumanistes. C’est aussi une idéologie potentiellement porteuse d'espoir. Espoir politique dans le sens ou l’on aperçoit un projet politique centré sur le développement de la technique et espoir qui remplace l’immortalité vendu pas les grandes religions puisque le transhumanisme laisse entre-apercevoir un mieux : une immortalité atteignable dans notre monde réel. Par ailleurs, à mon sens, son antithèse existe aussi dans l’idéologie des mouvements décroissants. Attention je ne dis pas que le post humanisme c’est la croissance et la consommation… Mais penser que la croissance ne soit pas un indicateur de progrès valable n’est pas une originalité du mouvement décroissant. Par contre une spécificité à mon sens caractéristique de ce mouvement est une forte hostilité à la technique. A noter que quand je parle de décroissance je ne parle pas développement durable d’écologie, ou même de certaine forme de simplicité volontaire, tout cela est tout autant compatible avec le post humanisme qu’avec la décroissance. Mais que j’oppose un mouvement (le posthumanisme) qui cherche ledéveloppement et le progrès humain par la technique et un autre mouvement (la décroissance) qui cherche à imaginer un développement sans cette même technique. Ce qui est assez ironique c’est que ces mouvements ont tout deux une filiation avec le mouvement hippiedes années 70. Filiation idéologique pour le transhumanisme. Et filiation au minimum au niveau de l’image pour les décroissants. Vous l’aurez compris présenté comme ça je me place plutôt du côté des transhumanistes… Néanmoins ce rêve d’immortalité qui caractérise aussi le transhumanisme pause de nombreux problèmes dont le plus évident est la surpopulation. On peut imaginer ce problème résolu par un uploading massif mais ce n’est forcément possible ni forcément satisfaisant. Un contre argument que j’ai vu fréquemment avancé par les transhumanistes est la faible natalité des pays où l'espérance de vie est haute. Cet argument me semble assez naïf. A la rigueur l’option conquête spatiale me semble être un contre-argument plus réaliste mais là encore, un tel projet pourrait difficilement se réaliser avant que le problème de la surpopulation ne se pose. Le transhumanisme propose aussi, j’ai l’impression, mais ce n’est pas vraiment propre au transhumanisme, une vision utilitariste de la science… La science n’est plus une pure recherche de la connaissance mais un moyen de réaliser une innovation technique qui préexiste virtuellement dans l’imaginaire. De même, la question de l’accès équitable de ces technologies en devenir à l’ensemble de la population se pose. Il est heureux que des associations transhumanistes posent cette question, il est davantage inquiétant qu’elles ne proposent pas de mécanismes permettant de s’assurer cette équité. À mon sens, le risque est plus là que du côté des dystopies totalitaires. Conclusion Pour terminer, on oppose souvent au transhumanisme que la vie immortelle perdrait son charme, sa beauté, deviendrait ennuyeuse… Pourtant, personnellement je peux difficilement imaginer quelque chose de plus charmant, de plus enthousiasmant que d’avoir le temps d’explorer tous les aspects de la culture, de voir progresser les connaissances humaines, et de partir découvrir l’univers… Et si après avoir occupé quelques milliers d’années on s’ennuie… Alors il sera toujours temps de mourir.

Cet épisode est un peu spécial puisqu'il s'agit d'un crossover entre podcast science et vie artificielle. Vous le retrouverez donc aussi en tant qu'épisode 73 de podcast science. Il est aussi particulièrement long (1h30). J'ai assez mal évalué le temps nécessaire à l'exposé de mon dossier. Vous pouvez me retrouver sur twitter (https://twitter.com/Xilrian) et vous abonner sur : notre flux RSS (http://feeds.feedburner.com/vieartificielle), iTunes (http://itunes.apple.com/fr/podcast/vie-artificielle/id471402436), Youtube (http://www.youtube.com/channel/UCuPLI-CCXwPeCuwsQQUcN-Q/videos) et soundcloud (https://soundcloud.com/xilrian). Le dossier Quelques définitions : L’idée directrice du transhumanisme est que nous approchons d’un tournant où la science et la technique vont rendre possible la création d’un homme pas – ou moins – soumis au vieillissement, et qui aura des capacités intellectuelles et physiques supérieures. Un post-humain ! En découle une volonté de changer l’homme. Pour les transhumanistes, cet objectif sera rendu possible par les progrès de la technique et aboutira au changement de la nature humaine. Derrière le post humanisme se cache une grande confiance en la science et une croyance en l'existence d’un progrès. Et si le terme n’était pas connoté négativement je dirais que le post humanisme est une forme de scientisme. Au passage vous vous demandez sûrement s’il faut faire une distinction entre “trans” et “post” humanisme. Il me semble que dans le monde anglo-saxon le terme transhumanisme est beaucoup plus utilisé. Il me semble aussi qu’il n’y a pas de définition universellement admise faisant une distinction claire entre ces deux concepts. Mais le terme transhumanisme insiste naturellement plus sur la transition c’est à dire l’amélioration de l’homme actuel. Tandis que le terme post humanisme peut faire référence à un posthumain ayant éventuellement quitté son statut d’humain. La singularité est une idée, attribuée à John Von Neumann un brillant savant américain des années 40-50 dont les auditeurs de vie artificielle ont déjà entendu parler. JVN est l’un des pères de l’informatique avec Alan Turing et c’est aussi le créateur du concept de singularité technologique. Le concept de la singularité est qu’il y a une «accélération accélérée» du progrès technologique humain et que, si l’on représente ce progrès par une courbe, on approche d’une sorte de tangente verticale. Pour les partisans de la singularité, quand on passera ce point, cette tangente, la singularité, les progrès technologique seront si importants que l’on aboutira à une sorte d’explosion de l’intelligence dont les conséquences sont quasi impossibles à imaginer. La singularité est souvent présentée comme reliée à l’informatique : aux lois de Moore et à des Intelligence Artificielles ou des machine capables de créer des versions améliorées d’elles-mêmes. Ce qui est dans la droite lignée des travaux de John Von Neumann. Il est aisé d’imaginer que la singularité technologique puisse être conçue comme un moyen de créer des posthumains. L'extropie, que l'on va aussi retrouver chez certains transhumanistes est l’idée que l’on soit capable, par la technique d’inverser l’entropie de l’univers. Ce qui semble pour le moins utopique. Rapide historique Les gens qui présentent le transhumanisme signalent généralement, il me semble à juste titre… Qu’il s’inscrit dans la droite lignée de traditions scientifico-mystiques bien plus anciennes qui, elles aussi, cherchaient à découvrir les moyens d’accéder à l’immortalité. On peut citer la tradition gnostique du Christianisme, les recherches des alchimistes, certaines religions orientales… La légende de Gilgamesh. Héro sumérien cherchant à acquérir l’immortalité est aussi très fréquemment citée. Plus récemment le transhumanisme est aussi un descendant de l’humanisme et des lumières dans le sens où il se conçoit comme étant une idéologie fondamentalement rationnelle. Et qu’il met l’amélioration de la vie humaine au centre de son dispositif idéologique. Le terme transhumanisme apparaît à la fin des années 50. Mais le transhumanisme tel qu’on le connaît aujourd’hui ne se structure en organisation que dans les années 90 sur des idées provenant des 60 à 80 comme la vague hippie. Ou des idées comme la sémantique générale qui postule qu’on peut changer l’homme, l’améliorer, en changeant le langage. On retrouve dans les mouvements transhumanistes les influences de trois idéologies qui s’entrecroisent : une gauche humaniste, un libertarianisme individualiste et un mouvement hippie en quête de sens… En revenant un petit peu sur le mouvement hippie je vais vous parler de Timothy Leary qui représente assez bien l’excroissance technophile de ce mouvement. Il est connu pour avoir été l’un des prophètes du LSD. Mais aussi un scientifique reconnu pendant une partie de sa vie. Il développa peu avant sa mort un projet prônant l’augmentation de l'espérance de vie ainsi que l'extension de l’intelligence humaine, le tout associé à de la conquête spatiale. Trois thématiques qu’il est à mon sens cohérent d’associer et que l’on retrouvera dans le mouvement transhumaniste. Les idées qui intéressent les transhumanistes sont souvent à la frontière de la science. Leurs idées ne sont pas franchement dans les pseudosciences, mais elles restent souvent assez marginales. L’imagerie transhumaniste provient en grande partie la SF et du cyberpunk. Mais je ne vais pas du tout développer cet aspect dans ce dossier. On peut tout de même citer le neuromancien de William Gibson comme œuvre ayant inspiré le mouvement et Serial Experiments Lain comme exemple d’œuvre inspirée par les idées transhumanistes. Les organisations transhumanistes des années 90 à nos jours : La première organisation transhumaniste à apparaître est l’extropy institute qui est fondée en 1992 et qui a disparu depuis. On retrouve ici, au moins dans le nom choisi pour l’association, un objectif particulièrement ambitieux, voire irréaliste. Par ailleurs, politiquement, l’institute était semble-t-il particulièrement libertarien et sans doute plutôt à droite. L’organisation a disparu en 2007 même si sa mailing-list reste plutôt active. De l’autre côté, avec des ambitions affichées beaucoup plus raisonnable, apparaît en 1998 l'association mondiale de transhumanisme world transumanism association qui s’est depuis renommée humanity+. Elle propose deux définitions complémentaires du transhumanisme : Le mouvement culturel et intellectuel qui affirme qu'il est possible et désirable d'améliorer fondamentalement la condition humaine par l'usage de la raison, en particulier en développant et diffusant largement les techniques visant à éliminer le vieillissement et à améliorer de manière significative les capacités intellectuelles, physiques et psychologiques de l'être humain. L'étude des répercussions, des promesses et des dangers potentiels de techniques qui nous permettront de surpasser des contraintes inhérentes à la nature humaine ainsi que l'étude des problèmes éthiques que soulèvent l'élaboration et l'usage de telles techniques. On voit donc ici que l’association se place non seulement en promoteur de la technique mais aussi comme un lieu de réflexions aux conséquences éthique de l’arrivée d’un post humain. Dans la même lignée peut être encore un peu plus orienté vers le centre gauche si il faut la situer politiquement on trouve aussi une association française qui s’appelle Technoprog'. Enfin à l’opposé, je dis à l’opposé car le monsieur ne me semble pas forcément outre mesure sympathique, il y a la singularity university de Ray Kurzweil. Le projet est en grande partie financé la NASA et par Google et son directeur Larry Page. L’association organise entre autre une Université d’été où les places sont extrêmement prisées. Le projet semble intéressant mais vu d’assez loin j’ai l’impression qu’il est très, trop orienté business et Networking. Ça semble davantage être l’endroit pour trouver comment commercialiser une invention révolutionnaire qu’un rassemblement de chercheurs. Le deuxième point négatif tient pour moi à la personnalité de Ray Kurzweil : Ray se comporte comme un commercial. On a fréquemment l’impression qu’il cherche à vendre quelque chose. Et c’est souvent réellement le cas. L’homme nous vend une singularité que nous allons voir dans quelques année, il se vend lui même comme un génie alors que ses réalisations semblent assez modeste. J’ai lu en partie l’un de ses ouvrages les plus connu Fantastic Voyage, en français serons-nous immortels ? Je m’attendais à me trouver face à un livre de prospective me ventant des technologies qui allaient augmenter notre espérance de vie… Il y a de ça, un tout petit peu mais le livre est surtout un livre de régimes se proposant de nous expliquer comment nous alimenter pour augmenter notre espérance de vie. C’est déjà assez décevant. Mais en plus Kurzweil suggère dans le régime qu’il propose, d’acheter une série de compléments alimentaires, compléments alimentaires vendu par une société… De Kurzweil lui-même. L’homme ressemble un peu à un richissime propriétaire de plusieurs restaurants étoilés qui s'apprêterait à écrire un guide des meilleurs restaurants… On ne peut s'empêcher de trouver ça suspect. Gravite aussi autour de la singularity university des gens comme Craig Venter. Un scientifique ayant grandement contribué au séquençage du génome humain et étant devenu riche suite à la revente de son entreprise. L’homme travaille actuellement sur la biologie de synthèse et a plus ou moins créé la première cellule vivante artificielle. J’ai une citation de lui qui m’avait été retransmise lors de l’ECAL11 (une conférence européenne bisannuelle sur la vie artificielle) mais dont je n’ai pas retrouvé la trace. Elle résume néanmoins assez bien le personnage. Une journaliste l’interroge et lui demande: “Don’t you think you are playing god modifying life like this? And Craig answers: But who said we are playing?” Venter reste quelqu’un d’intéressant. De même, je n’ai rien contre Google, au contraire. Mais l’association Google Venter Kurzweil NASA donne un sentiment un peu mitigé à l’ensemble on sent poindre quelque chose d’assez médiatique, mégalo et business. Il existe au moins une dernière association transhumaniste, dans laquelle est aussi impliqué Kurzweil, le singularity Institute.

Bioengineers have been steadily advancing toward the goal of building lab-grown organs out of a patient's own cells, but a few major challenges remain. One of them is making vasculature, the blood vessel plumbing system that delivers nutrients and remove waste from the cells on the inside of a mass of tissue. Without these blood vessels, interior cells quickly suffocate and die. Scientists can already grow thin layers of cells, so one proposed solution to the vasculature problem is to "print" the cells layer by layer, leaving openings for blood vessels as necessary. But this method leaves seams, and when blood is pumped through the vessels, it pushes those seams apart. Bioengineers from the University of Pennsylvania have turned the problem inside out by using a 3D printer called a RepRap to make templates of blood vessel networks out of sugar. Once the networks are encased in a block of cells, the sugar can be dissolved, leaving a functional vascular network behind. "I got the first hint of this solution when I visited a Body Worlds exhibit, where you can see plastic casts of free-standing, whole organ vasculature," says Bioengineering postdoc Jordan Miller. Miller, along with Christopher Chen, the Skirkanich Professor of Innovation in the Department of Bioengineering, other members of Chen's lab, and colleagues from MIT, set out to show that this method of developing sugar vascular networks helps keep interior cells alive and functioning. After the researchers design the network architecture on a computer, they feed the design to the RepRap. The printer begins building the walls of a stabilizing mold. Then it then draws filaments across the mold, pulling the sugar at different speeds to achieve the desired thickness of what will become the blood vessels. After the sugar has hardened, the researchers add liver cells suspended in a gel to the mold. The gel surrounds the filaments, encasing the blood vessel template. After the gel sets it can be removed from the mold with the template still inside. The block of gel is then washed in water, dissolving the remaining sugar inside. The liquid sugar flows out of the vessels it has created without harming the growing cells. "This new technology, from the cell's perspective, makes tissue formation a gentle and quick journey," says Chen. The researchers have successfully pumped nutrient-rich media, and even blood, through these gels blocks' vascular systems. They also have experimentally shown that more of the liver cells survive and produce more metabolites in gels that have these networks. The RepRap makes testing new vascular architectures quick and inexpensive, and the sugar is stable enough to ship the finished networks to labs that don't have 3D printers of their own. The researchers hope to eventually use this method to make implantable organs for animal studies. Text by Evan Lerner Video by Kurtis Sensenig

James Maxey (author), Jim Craig (planetarium director), Ben Davis (nuclear physicist) and myself are today's speakers. Topic: "The Year in Science" (Part 1). Subtopics: The good and bad of 3D printers. Such as the 3D printing of food for human consumption, of a mouse kidney for transplant, of replacement parts for US army weapons, of artificial limbs for amputees, and of impossible to find parts for antique cars. But also the unemployment which will likely be a byproduct of 3D printers.  Also discussed: the discovery of a transitional ancestor of turtles with only half-developed shells; and the universe taken as whole might not be elegant after all since the Higgs boson has turned out to be too light to bring balance to the universe. Dr. Adrian Bowyer's self-replicating rep-rap machine is also described.  Hosted by Stephen Euin Cobb, this is the July 3, 2013 episode of The Future And You. [Running time: 31 minutes] This is the first half of a panel discussion recorded before a live audience at the SF&F convention ConCarolinas in Charlotte NC on June 1, 2013.

Jacob Krogsgaard (atmospheric scientist and project manager) is today's featured guest. Topics: Possible ramifications of self-replicating 3-D printers, such as the RepRap Machine by Dr. Adrian Bowyer. Also: open-source designs, crowd-funding, the stock market micro-crash, the Augmented Reality glasses such as the Google Glass project, and computers wired directly into the human brain. As well as his observation that our current generation of technology seems to be super-empowering volunteer activities of every type such as Librivox and Wikipedia; and his notion that artificial intelligence may be more useful if it does NOT mimic human styles of thinking. Hosted by Stephen Euin Cobb, this is the December 26, 2012 episode of The Future And You. [Running time: 29 minutes] This interview was recorded using Skype on December 1, 2012. Jacob Krogsgaard is currently working (along with Tom Canton) to create a documentary film which will promote the idea of using of a mass driver as a space launch system to the general public (as well as to the scientific and political communities) as an alternative to rockets and space elevators. Jacob Krogsgaard is an atmospheric scientist and project manager. Tom Canton is a experienced director of business, training and music videos. BTW: I interviewed Dr. Adrian Bowyer about his RepRap 3-D Printer Project on September 17, 2008 Episode. That episode--like all past episodes of this show--remains available for your listening pleasure. It can be found here.

Bryan Bishop (Assistant Director for R&D at Humanity Plus) is today's featured guest. Topics: open source hardware and software; 3D printers (sometimes called rapid prototyping machines or RepRap machines); The GADA Prize (a contest for people who build 3D printers); do it yourself biotechnology and do it yourself  transhuman augmentation; the possibility of using 3D printers to print tissues and organs for transplant into patients who need them; artificial intelligence and the singularity; and an interactive web page that lets you estimate the arrival date of the singularity based on your own estimation of technological trends. Hosted by Stephen Euin Cobb, this is the March 16, 2011 episode of The Future And You. [Running time: 30 minutes]. This interview was recorded as a Skype-to-Skype call on March 12, 2011. Bryan Bishop is Assistant Director for research and development for the non-profit organization Humanity Plus (which focuses on Human enhancement technology). He speaks at conferences on open source hardware and do-it-yourself biology. He does software development and fund-raising to promote both software and hardware development within the open source community. He runs the open manufacturing group on the web (a community group where people share thier ideas about these topics). And he has a background in mechanical engineering and computational neuro-science.

Doctor Adrian Bowyer (inventor of the RepRap machine) is our featured guest. The RepRap machine is the first machine in all of human history that can make most of its own parts. Not all of them (at least not yet) but most. This means that with a good bit of human assistance and intervention it can do two things that for six hundred million years only biologically living things could do: Reproduce and Evolve. What's more, the material the machine needs to make more of itself can be grown in your garden. And Doctor Bowyer (who is an engineer and mathematician at the University of Bath in England) has made the design of the machine freely available to anyone who would like to build one by declaring it Open Source. All this would be meaningless of course if the machine could only make more copies of itself but it has already made shoes, coat hooks, door handles, gears, plastic jewelry, cups, flasks, and a shot glass for toasting its own creation. A few months ago on May 29, 2008 its first offspring, its first 'child machine,' was assembled and was immediately used to make one of the components needed to make a grandchild machine. Which means that its reproduction and evolution has already begun. Hosted by Stephen Euin Cobb, this is the September 17, 2008 episode of The Future And You. [Running time: 83 minutes] Where this will all lead is still uncertain. If the good doctor has his way, in a few years millions of them will exist in homes all around the world, happily churning out useful and decorative household items at ridiculously low cost. From New York City to Bangladesh, no place would be left out. If enthusiasm remains strong, they might quickly spread everywhere. Because if your friend or neighbor or relative has one and you don't, you can ask them to have theirs make one for you too.
