The Explosive Growth of 3D Printing 213

MojoKid writes "If you've ever attended a World Maker Faire, the first thing that strikes you is how organic the whole scene is. Inventors, creators, and engineers from all walks of life have their gadgets, science projects, and creations on display for all to see. Some of the creations you see on display range from downright amazing to completely bizarre. One of the big attractions, a technology area that has experienced explosive growth, is the land of 3D Printing. MakerBot took the open source RepRap 3D replicator project mainstream back in 2009 with the release of the Cup Cake CNC machine, then came the Thing-o-Matic and then a little bot called Replicator. With each iteration, improvements in process and technology are bringing better, more capable 3D printers to market, from MakerBot's new Replicator 2, to new players in the field like Solidoodle, Up!3D, Ultimaker, and Tinkerines. To watch a 3D printer in action is like witnessing art, science and engineering all working together in glorious unison."

MakerBot Going Closed Source? 182

An anonymous reader writes "A year after a windfall $10 million in venture capital, and after a community stir over one man's attempt to Kickstarter a project to manufacture the open source Replicator with a lower price tag, it appears that MakerBot Industries is going closed source on their new model 3d printer, the Replicator 2. Josef Prusa, core developer of the widely known RepRap printer (the basis for previous MakerBot models) has confirmed the sad news, with a stunned tweet, and is organizing an 'Occupy Thingiverse,' to protest the apparent theft of others' work."

Elon Musk, an Industrialist For the 21st Century 89

pacopico writes "Elon Musk has just come off a pretty amazing run. SpaceX docked with the ISS. Tesla has started selling its all-electric luxury sedan, and SolarCity just filed to go public. Bloomberg Businessweek spent a few days with Musk and got a look inside his insane factories in Silicon Valley and Los Angeles. It's like Willy Wonka time for geeks. Among the other proclamations in the story is Musk saying that he intends to die on Mars. 'Just not on impact.' Musk then goes on to describe a fifth mode of transportation he's calling the Hyperloop."

Injured Bald Eagle Gets New 3-D Printed Beak 103

An anonymous reader writes "A bald eagle that lost its beak to a poacher's gun receives a 3-D printed beak prosthetic like a dental implant." More (with pictures): "Mr Calvin, a founder of the Boise-based Kinetic Engineering Group, made a mold of Beauty's shattered upper mandible, laser-scanned it, fine-tuned it in a 3D modeling program, and created a prosthetic beak from a nylon-based polymer."

3D Printing On a Microscopic Scale 34

cylonlover writes "Three-dimensional printers are popping up everywhere these days. Some are small enough to fit in a briefcase and others are large enough to print houses, but scientists at the Vienna University of Technology are going for the microscopic. Earlier this year, the university built a 3D printer that uses lasers to operate on a tiny scale. Now they're refining the technique to enable precise placement of a selected molecule in a three-dimensional material. This process, called '3D-photografting,' can potentially be used to create a 'lab on a chip' or artificially grow living tissue."

Lexmark To Exit Inkjet Printer Market 228

Barence writes "Lexmark has announced it will stop making inkjet printers and cut 1,700 jobs as part of a cost-cutting restructuring move. Lexmark will stop all inkjet development worldwide by 2013, and close its Philippines-based inkjet supplies manufacturing plant by 2015. This will provide annual savings of $85 million, rising to $95 million by 2015. The total restructuring cost before tax is expected to be $160 million. The company is also looking into the possible sale of its inkjet-related technology." I know there are some purposes for which inkjets are good (modern home photo printing can be insanely good, and we've featured a lot of cool projects which use inkjets to print sensors, solar cells, antennae, and more), but I get just a little queasy whenever I see an inkjet printer purchased by an innocent friend or family member who doesn't realize quite how much it will end up costing them in the long run.

'Wiki Weapon Project' Wants Your 3D-Printable Guns 570

Sparrowvsrevolution writes "Earlier this month, University of Texas law student Cody Wilson and a small group of friends who call themselves 'Defense Distributed' launched an initiative they've dubbed the 'Wiki Weapon Project.' Their goal: to raise $20,000 to design and release blueprints for the world's first entirely 3D-printable gun. If all goes according to plan, RepRap users will soon be able to turn the project's CAD designs into an operational firearm capable of shooting at least one standard .22 caliber bullet, all in the privacy of their own garage. Wilson and his handful of collaborators at Defense Distributed plan to use the money they raise to buy or rent a $10,000 Stratysys 3D printer and also to hold a 3D-printable gun design contest with a $1,000 or $2,000 prize for the winning entry — Wilson says they've already received gun design ideas from fans in Arkansas and North Carolina. Once the group has successfully built a reliable 3D-printed gun with the Stratysys printer, it plans to adapt the design for the cheaper and more widely distributed Reprap model. The group had already raised more than $2,000 through the fundraising platform Indiegogo, but the site took down their page and froze their funds on Tuesday. They're continuing to seek donations through their website via Paypal and Bitcoin."

Color Printing Reaches Its Ultimate Resolution 140

ananyo writes "The highest possible resolution images — about 100,000 dots per inch — have been achieved, and in full-colour, with a printing method that uses tiny pillars a few tens of nanometres tall. The method could be used to print tiny watermarks or secret messages for security purposes, and to make high-density data-storage discs. Each pixel in these ultra-resolution images is made up of four nanoscale posts capped with silver and gold nanodisks. By varying the diameters of the structures (which are tens of nanometres) and the spaces between them, it's possible to control what colour of light they reflect. As a proof of principle, researchers printed a 50×50-micrometre version of the 'Lena' test image, a richly coloured portrait of a woman that is commonly used as a printing standard (abstract). Even under the best microscope, optical images have an ultimate resolution limit, and this method hits it."

MIT Students Reveal PopFab, a 3D Printer That Fits Inside a Briefcase 49

cylonlover writes "There are plenty of different 3D printers to choose from these days, from the popular Makerbot Thing-O-Matic to the budget-priced Solidoodle. These all have one drawback, however, in that they aren't exactly portable. Most need to be disassembled to be moved, and even the fully-assembled Cubify printer isn't really built for travel. But now, two MIT students have developed the PopFab, a machine that does 3D printing and more, all while fitting inside a small suitcase. With different heads, the machine could also be used for milling, vinyl cutting, drawing, and much more, to create a wide variety of objects. The creators have also tested its portability by traveling with it as a carry-on suitcase to Saudi Arabia, Germany, and within the U.S."

Harvard Software 3D Prints Articulated Action Figures 75

An anonymous reader writes with an excerpt from an article at Geek.com "A team of computer scientists at Harvard University have developed a piece of software that allows anyone to 3D print their own action figures at home. Not only will the models carry the likeness of the character, they will also be fully articulated. The software can take an animated 3D character and figure out where best to place its joints. In what is referred to as reverse rendering, the software first looks at an animated character's shape and movement and identifies the best joint points (original paper, paywalled). It then adjusts the size of the different parts of the model so as to allow a real joint to work once printed. Optimizations are then carried out to produce a model as close as possible to the on-screen version, but at the same time workable as an actual real-world, articulated 3D model." The bad news: Harvard is patenting everything and wants to commercialize it on a proprietary basis. The good news: An anonymous reader pointed toward the paper in full.

Additive Manufacturing (3D Printing), Gun Control, and Patent Law 380

retroworks writes "J.D. Tuccille of the conservative think tank Reason Foundation discusses last week's news about the first working 3D-printed gun. According to the original article, the partly plastic '.22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper' fired 200 rounds without any sign of wear and tear. Tuccille takes the discovery in the direction of politically topical gun control. '...the development makes it clear that a wide range of bans, restrictions and prohibitions are becoming increasingly unenforcable.' But in my mind, this example of additive-manufacturing technology raises even more questions about patent law enforcement. Will 3D printing be to the Anti-gray-market-alliance what online porn became to neighborhood blue laws?"

The World's First 3D-Printed Gun 846

MrSeb writes "An American gunsmith has become the first person to construct and shoot a pistol partly made out of plastic, 3D-printed parts. The creator, who goes by the name HaveBlue and is an AR-15/M16 enthusiast, has reportedly fired 200 rounds with his part-plastic pistol without any sign of wear and tear. HaveBlue's custom creation is a .22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper. In other words, the main body of the gun is plastic, while the chamber — where the bullets are actually struck — is solid metal. ... While this pistol obviously wasn't created from scratch using a 3D printer, the interesting thing is that the lower receiver — in a legal sense at least — is what actually constitutes a firearm. This means that people without gun licenses — or people who have had their licenses revoked — could print their own lower receiver and build a complete, off-the-books gun." Here come the illegal shapes. Note that the legal fiction of receiver-as-firearm is true in the U.S., but may not be in other jurisdictions, and that no gun license is required in most of the U.S. to purchase or possess a semi-automatic weapon.

Video Meet the Robisons and Their Low-Cost RepRap Kit (Video) Screenshot-sm 67

It seems like less than an hour since Slashdot ran a Report From HOPE: The State of Community Fabrication. Now we have a video about a Massachusetts mother and son team we met at HOPE that had so much trouble with commercial RepRap machines that they designed their own and started marketing it under the name Robison Industries, a company they seem to be starting on the fly that uses their local hackerspace as its manufacturing location. Interested in RepRap? Maybe not yet, but as devotees of the concept point out, nobody outside a small circle of geeks was interested in personal computers at first, but they're ubiquitous today. Will we all have 3D printers on our desks in a few years? Good question. round us up in 2020 or 2025 at our local hackerspace and we may have an answer for you.

Report From HOPE: The State of Community Fabrication 32

Four years ago, there were around ten hackerspaces across America; today, Hackerspaces (Techshops, Makerspaces) are within driving distance of a good chunk of the population. The RepRap can be assembled for a moderate price, and those with a bit more cash to burn can get one preassembled from multiple sources. Makerfaires are held in most major cities, sites like Instructables and Hackaday are thriving, and all things "Maker" are cool. Far McKon was at HOPE 9 giving an update on how far community fabrication has come since his 2008 presentation at the The Last HOPE (mp3 of the talk), what threats lie on the horizon, and where we might find ourselves in another four years.

Update: 09/20 21:02 GMT by U L : There's an audio recording of the talk available.

High Security Handcuffs Opened With 3D-Printed and Laser-Cut Keys 202

Sparrowvsrevolution writes "In a workshop Friday at the Hackers On Planet Earth conference in New York, a German hacker and security consultant who goes by the name 'Ray' showed that he could open high-security handcuffs from manufacturers Chubb and Bonowi with plastic copies of keys that he cheaply produced with a laser-cutter and a 3D printer. Both companies attempt to control the distribution of their keys to keep them exclusively in the hands of authorized buyers such as law enforcement. Lasercut plexiglass versions of the Chubb key, which opens handcuffs like the ones used in passenger airline restraints, were selling for $4 at the conference. Ray plans to post the CAD file for the key on the 3D printing site Thingiverse after LockCon later this week."

Student Creates World's Fastest Shoe With a Printer 144

An anonymous reader writes "Engineer and designer Luc Fusaro from the Royal College of Art in London has developed a prototype running shoe that can be uniquely sculpted to any athlete's foot. It's as light as a feather too, weighing in at 96 grams. The prototype is aptly named, Designed to Win, and is 3D printed out of nylon polyamide powder, which is a very strong and lightweight material. The manufacturing process uses selective laser sintering (SLS), which fuses powdered materials with a CO2 laser to create an object. This process means 3D scans can be taken of the runner's foot so as to ensure the shoe matches the shape perfectly. Fusaro can also change the stiffness of the soles according to the athlete's physical abilities. The shoe can improve performance by 3.5%, meaning a 10 second 100-meter sprinter could see his time drop by 0.35 seconds, which is a huge time saving relatively speaking. Imagine if Usain Bolt put a pair of these running shoes on."

How Open Source Hardware Is Driving the 3D-Printing Industry 199

TheNextCorner sends this quote from ReadWriteWeb: "Open source software has been a key player in all kinds of disruptive technologies — from the Web to big data. Now the nascent and growing open source hardware movement is helping to power its own disruptive revolution. ... As 3D printing, powered by Arduino and other open source technologies, becomes more prevalent, economies of scale become much less of a problem. A 3D printer can print a few devices — or thousands — without significant retooling, pushing upfront costs to near-zero. This is what The Economist calls the 'Third Industrial Revolution,' where devices and things can be made in smaller, cleaner factories with far less overhead and — significantly — less labor."

Minecraft Map of Northwestern Campus Printed In 3D 70

erich666 writes "Ben Rothman has created a five-foot-wide scale model of most of Northwestern University, where he was a sophomore this past year. This campus model is unique: it is the first modeled in Minecraft and then printed on a 3D printer. It is also the largest Minecraft 3D print to date, and will be on display in the main lobby of the largest building on campus in a few weeks. Ben began in November and spent about 600 hours recreating the campus. He notes that "this felt like playing a game more than a modeling task." The cost of the print material was about $2000 to $2500, well less than the cost of the display case being built for it (admittedly, labor costs are included for the case). The free Mineways program was used for export. It can help upload an exported Minecraft model to Shapeways, i.materialise, or other 3D print service. Models cost as little as $5."

MIT Professor Pushes the Envelope of 3D Art and Manufacturing 58

kkleiner writes "Professor at MIT Neri Oxman's creations are demonstrating the powerful combination of 3D printing and new design algorithms inspired from nature. Just as a computer printer makes copies of 2D images, 3D printers have copied an impressive variety of objects, such as robots, chairs, prosthetics, kidneys, and jaw bones, to mention a few. But Oxman and her colleagues are discovering new design and engineering principles that will help to mature 3D printing into a technology capable of producing complex and beautiful structures impossible by other manufacturing techniques."

Ask Slashdot: Best Option For Printing Digital Photos? 350

rrossman2 writes "With the birth of our son (who is now just over two), we have snapped and accumulated a ton of pictures — on Panoramio, Picasa, Facebook, etc. What is the best option for bulk printing the photos to a physical format? We all know how fast technology advances, as well as how fast sites come and go; I want a way to have these pictures for my son when he is older... just like my grandfather has photos of himself from World War II, my parents have photos of me when I was little, etc. Are there any affordable services that you can upload the photos to that print and deliver long-lasting pictures? How well do today's photo ink jets last, and what's the best type of paper? I do have a cheaper Samsung color laser printer, but color lasers don't make the most color-rich prints, and using normal photo paper you can find in big box stores doesn't work out too well, as the laser toner seems to peel off on the rollers and gum things up. (Is there a good long lasting paper that seems to work well with laser printers?) I can see what's going to happen in the future: all of the digital photos people take now are going to either end up on a website that won't be around in 20+ years, or get stuck on disks or flash memory that won't last, or for which interfacing with the media will become difficult or impossible."
