3D printing gets more flexible with Nylon extrusion
3D printing with ABS and other plastics that have a low-melting point are old hat. And, with the price of entry dropping below the $500 mark, soon enough anyone will be able print their own pirated 45s. Instructables user [taulman] has has taken it upon himself to push the DIY polymer extruder scene in a new direction -- Nylon. The slick and bendable Nylon 6 melts at 320 degrees celsius, roughly 100 degrees higher than the more common and brittle ABS. The flexible nature of nylon has some obvious advantages, particularly when printing tubing or even an iPhone case. What's more, gears and bearings created from the synthetic don't need to be lubricated. But, this isn't the end game for [taulman]. The resourceful DIYer plans to keep working on his high-temperature system until he can build custom creations from Delrin and Polycarbonate. The obvious downside here, is that higher temperatures require more power and more rugged components that could drive up cost. But, we'd say it's a small price to pay for being able to print your own Otterbox. Check out the video demos after the break.
Burritob0t hands-on (video)
ITP, or the Interactive Telecommunications Program at the Tisch School of the Arts at NYU churns out some of the most reliably interesting tech-centric artists in the world. Every so often, the school opens its doors to the public and the press and, of course, we jumped at the chance to see what the grad students were cooking up... literally. Marko Manriquez took the opportunity to showcase his thesis project, the Burritob0t, a 3D printer the spits out edible piles of beans and cheese, instead of non-toxic (but, highly inedible) plastic. The base is built largely around a standard RepRap machine, with the Frostruder attachment from MakerBot. From there it's pretty simple to plug in any 3D model and build your creation from highly-processed Mexican food -- on a heated platform from the Thingomatic, of course. Marko says that his creation not only seemed like a logical way to combine "edible bits and digital bytes" but also a way to address the increasingly mechanized food industry and our growing reliance on manufactured "food." Sadly, we weren't able to get a complete demo on the show floor. The current incarnation of the device relies on air pressure to push the ingredients through syringes, and firing up the compressor was not an option. A Kickstarter is forthcoming, however, and Marko plans to upgrade the components to ditch the bulky and loud compressor. He also hopes to actually serve food from his printer, perhaps by taking up residence in a park. But, we suspect it'll be a while before you can get a Burritob0t burrito while you wait for your Concrete from Shake Shack. Check out the video after the break. %Gallery-155478%
US Navy LASR research facility builds robots, not ray guns
The US Navy announced a new robotics research facility this week located within the existing Naval Research Laboratory's main site in Washington D.C. The Laboratory for Autonomous Systems Research, or LASR, was created to support NRL research in "robotics and autonomous systems of interest to the Navy, the Marine Corps and the Department of Defense," wrote LASR director Alan C. Shultz, mentioning that a familiar sounding autonomous firefighting robot would be among the lab's projects. The new facility is kitted out with a litany of realistic environmental simulation bays, allowing NRL scientists to pit their research against the elements with ease. Researchers will also have access to machine shops stocked with 3D printers and other goodies, a power and energy lab, a sensor lab and what Shultz calls the "world's largest space for real-time motion capture." Sounds great, at least as long as the research projects never get ahold of a certain Navy-funded AI report. Check out Shultz' official statement at the White House blog link below.
Inhabitat's Week in Green: i-oniq hybrid, spherical solar cell and an incredible LEGO printer
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. This week epic green transportation initiatives kicked off around the world as Inhabitat reported that Shenzhen, China launched the world's largest electric vehicle fleet and London's brand new Eco-Routemaster hybrid bus hit the streets for the first time.

Audi also turned heads with its souped-up R18 E-Tron Quattro hybrid Le Mans racer, and Perave's 350 MPGe MonoTracer electric motorcycle hit the market.It was also a bright week for renewable energy with a revolutionary spherical solar cell capable of capturing light from all directions, and Austria Solar sending out a "sun-powered" annual report that only appears when exposed to sunlight. Meanwhile, we said goodbye to the polluting energy technology of the past as Midwest utilities shuttered 10 fossil fuel-powered plants and the world's oldest nuclear reactor closed up shop in the UK. Brilliant designers also chased away dark winter days with a sunflower-shaped heliostat that can flood any house with natural light and a cheap, photovoltaic Little Sun lamp for the developing world.Green tech also wired the world in exciting new ways as the Smithonian Institute announced plans to replicate and share its collection with the world using 3D printing tech and a 14-year-old boy invented an incredible LEGO printer. We also watched HP launch an all-in-one workstation that pops open for easy DIY upgrades and repairs, while Huawei unveiled a soaring Pegasus sculpture made from 3,500 smartphones. Last but not least we brought you a look at Google's new Terminator-style augmented vision goggles, and we shared a fun tutorial on geocaching with your children.
Paint3D app promises to let you sketch and print 3D models straight from Android
3D printing may still have quite a ways to go before it becomes as ubiquitous as traditional printing, but there's plenty of developers out there working to make that happen. One such example comes out of the House 4 Hack group in Johannesburg, who have been working on an Android app called Paint3D that promises to let folks create 3D models and then print them out straight from their mobile device -- imagine saying that even just five years ago. Unfortunately, that's not available to the general public just yet, but you can get a closer look at the app and the results its able to produce at the source link below, and get an overview from one of the developers in the video after the break.
Drexel University turns to 3D scanners, printers to build robotic dinosaurs
3D printers, 3D scanners and robotics are usually more than enough on their own to get us interested in something, but a team of researchers at Drexel University have played one other big trump card with their latest project -- they've thrown dinosaurs into the mix. As you can probably surmise, that project involves using a 3D scanner to create models of dinosaur bones, which are then reproduced (at a somewhat smaller scale) using a 3D printer. The researchers then hope to use those to build working robotic models that they'll use to study how dinosaurs and other prehistoric animals may have moved and lived in their environments. That work will start with a dinosaur limb that they expect to have completed by the end of the year, after which they say it will take a year or two to build a complete robotic dinosaur replica.
83-year old woman gets replacement 3D printed titanium jaw, makes her the coolest member of the bridge club
3D printers are continuing to force their way into medical circles and the latest beneficiary is an 83-year old woman. She's the first to receive a titanium jaw crafted by those not-so dimensionally-challenged printers. The method was developed by the BIOMED Research Institute at Hasselt University in Belgium and creates the lower jaw replacement from layer-upon-layer of titanium dust. A computer-controlled laser then ensures that the correct molecules are fused together. The technique, the first to replace the entire jaw, takes mere hours to make the substitute choppers, while previous options would take several days. Although the final product weighs a bit more than its natural predecessor, but that didn't stop the patient returning close to "normal speaking and swallowing" the day after the operation.

MakerBot releases free-to-download Playsets, will have you printing a Captain Kirk Chair in no time
So, you've always wanted to build a dollhouse out of ABS plastic? Well here's your chance. MakerBot has announced the release of its "MakerBot Playsets," a collection of free-to-download schematics used to create objects such as dolls, dollhouses and furnishings with the company's 3D printer. The files are available in .stl and .dxf formats for use with CAD programs, and take away the guesswork involved in coming up with a uniform design for larger projects. Take a look at the current collection -- including such objects as a Telescope, Moon Rover, Captain Kirk Chair, Treasure Chest and Suit of Armor -- and see what you think. You'll find the entire collection at the Thingiverse link just below.
Sculpteo brings 3D printing to the iPhone
Sculpteo is a fascinating French company that's working to bring 3D printing to the masses. The company had a booth at CES, and while some of our chat with them had to go through a French/English barrier, they very nicely explained to us how they're doing business and allowing almost anyone to make custom 3D printed objects, even through iOS. The company can print custom items through its official website. You can upload your own 3D object file, and by following its web interface, you can have Sculpteo print the object out on demand. I chatted with Sculpteo's rep about how easily that worked, who agreed that while the process itself is generally pretty easy, there are usually a few tweaks that have to be made. Obviously a digital 3D object is not subject to the laws of physics, so sometimes things have to change in the object to make sure it stands up under gravity and can exist at the dimensions planned. But generally, Sculpteo can print out almost anything that someone has previously put together into a 3D file, either on a Mac or PC. However, the most interesting part of the company (and the real showpiece at CES this year) is the iOS app. The app isn't quite as open as the web interface (you can't just upload your own 3D files), but it does allow you to create custom 3D objects like pre-designed mugs, vases, or even iPhone cases, then customize those things directly from your phone. Created items usually cost from $30 to $40; once created, iOS users can order items right from their devices with immediate shipment. The 3D printing quality is touch and go. Some of the objects Sculpteo showed off had a sort of glaze over the 3D printing powder, but some items, including an iPhone case, were still very dusty to the touch. It's unclear if those objects were just on display or finished products meant for end users. Assuming that the printing process finishes everything correctly, the end result is that almost anyone can create customized 3D objects on an iPhone or iPad, then get those renderings printed out into real objects. 3D printing has been around for a few years already (even for DIY hobbyists), but it hasn't been utilized by most of the public. 3D printers and the various costs associated with them are still a little too pricey for common mass market use, and many items created with 3D printing are still too fragile to be much more than showpieces. But Sculpteo hopes its app can "demonstrate the printing process" to the public and show that things like this are possible, even easy and relatively cheap. Sculpteo's app is a free download on the App Store. The company says its sales of 3D items have seen "an incredible response so far," and it's adding new patterns, items, and functionality to the app all the time.
Cubify brings 3D printer and Kinect app to CES
At this point it's kinda tough to get excited about 3D printing -- actual devices and services are a dime a dozen, but Cubify has a decidedly user-friendly vibe working in its favor. 3D Systems is rolling in to CES with its Cube 3D printer, but it'll also be showing off Cubify.com and its new Kinect-To-Print app. The app will allow users to design objects with "coloring book simplicity," then have them printed up and shipped to their door, or they can post their creations to the web for others to purchase and earn cash. The site will also be prepopulated with a selection of games and other custom objects ready to be printed on demand either at home on the Cube 3D or by the company and shipped out to customers. Cubify.com will go live in a beta version on January 10th and, while you wait, you can check out the video and PR after the break.
Mineways: Create 3D prints of your Minecraft creations, or pay someone else to
3D printers are, indisputably, super awesome. They're boxes full of magic, hope, and lasers, which create substance from nothing and reality from dreams. Coincidentally, Minecraft basically does the exact same thing, by providing the user with a cuboid sandbox for their imagination to run wild in. Now, these two worlds of creation can be joined together via Mineways, a 3D model-exportation tool created by Eric Haines. The process breaks down like this: Using Mineways, Minecraft players can select a portion of the world they've built and export it as a texture file and 3D model, in file formats compatible with the rendering software used by 3D printers. Those files can then be printed, creating an adorable little real-life version of whatever it is you had exported. If you're not part of the 1 percent and as such do not have access to a 3D printer, your exported files can be sent to a printing service like Shapeways, which does exactly what a 3D printing service sounds like it would do. Based on the size and complexity of the model, getting something printed can run from 25 bucks for a small doodad to several hundred dollars for a complete landscape. Somewhere, a very wealthy Minecraft/model train enthusiast is extremely pleased. Click here to grab the open source software directly from Eric, and to see an in-depth how-to guide.
Mineways offers up 3D-printed models of your Minecraft creations
Sure, those gigantic tributes to Italian plumbers look great on your PC screen, but sometimes you want something a little more tangible. That's exactly what Mineways lets you do. Yep, it's another demonstration of why we all need a 3D printer in our life, although this Minecraft-friendly software can also export your models across to 3D printing site, Shapeways, which will do the whole printing slog for you. Sure, it'll cost you, but it's likely to be a mere fraction of your own 3D printer. The Mineways program is based on the open-source mapping tool Minutor and creates both a data and texture file ready to pinged across to the Shapeways site. You can also attempt to reclaim some money from those many hours sunk into Minecraft by selling your creations on the site. Check the source below for tutorials, more examples and the latest version of the model exporter. [Photo credit: postapocalyptic]
3D-printed bone replacements coming soon to an orthopedic surgeon near you, courtesy of WSU (video)
3D printers are slowly, but surely working their way into all sorts of useful, everyday applications -- like the creation of chocolates, flutes and even Mario Kart turtle shell racers. Now, Washington State University engineers are unveiling a unique implementation of the tech that could aid in the regrowth of damaged or diseased bones. Utilizing a ceramic compound, the group's optimized ProMetal 3D printer builds dissolvable scaffolds coated with a plastic binding agent that serve as a blueprint for tissue growth. The team's already logged four long years fine tuning the process, having already achieved positive results testing on rats and rabbits, but it appears there's still a ways to go -- about 10 -12 years, according to the project's co-author Susmita Bose -- before orthopedic and dental surgeons can begin offering "printed" bone replacements. With a synthetic windpipe already under medical science's belt and now this, it's looking like we're just a few short decades away from that long sought after full body replacement. Right, Mr. Lagerfeld? Click on past the break for a brief look at this osteo-friendly machinery.

Insert Coin: SeeMeCNC H-1 cuts entry price to the world of 3D printing
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. Maybe it was the Turtle Shell racers, or the ability to crowdsource homes for crabs, but we're enthralled with the potential of 3D printers. Now, SeeMeCNC is looking to offer up its skeletal H-1 as "the most affordable" entry-level three-dimensional printer available. Its design roots come from the open source RepRap's latest self-replicating machine, the Huxley. However, there are a few differences here. SeeMeCNC has replaced several parts for injection molding, which apparently shaves a substantial chunk off the manufacturing costs. This includes using plastic roller bearings instead of metal bearings, while the machine has also been readjusted to inch measurements. Fans of the imperial system and 3D printing antics can peer beyond the break to judge whether the cut-price printer will still cut the mustard.
Project Shellter: crowdsourcing 3D-printed homes for hermit crabs
The fine folks at MakerBot have impressed us enough with their Mario-themed RC racers and self-replicating 3D printers, but now the collective is looking to save mother nature with Project Shellter. Turns out, there's a housing shortage in the oceans. Harvesting of shells has left many hermit crabs with no option but to take up residence in bottle caps and other debris they can squeeze their soft bodies into. MakerBot's Miles Lightwood, has decided to crowdsource designs for artificial shells that hermit crabs can live in. Right now Lightwood is testing different shapes, materials and colors, looking for the combination that the critters will find most attractive. The shells are not intended to be placed in the wild -- putting plastic into the sea wouldn't be very environmentally friendly. Instead, the artificial domiciles are meant for domestic use, reducing the number that must be harvested for pets. You can get updates on the project from its Facebook page (at the more coverage link) and submit your own designs to Thingiverse, just make sure to tag them "shellter."
Print your own blood vessels, no need for red toner
Barely 24 hours after we told you about printing your own bones, the franken-science continues with the announcement that blood vessels are next on the body-parts-you-can-print list. Unsurprisingly, you'll need more than just regular toner if you want to start printing your own at home, but pioneering work by application-oriented research organization Fraunhofer has claimed to have cracked it by adding some good old 'two-photon polymerization' into the mix -- yeah, obvious once you know. The added photon special sauce is what makes the printed synthetic tubes biofunctionalized, which in turn enables living body cells to dock onto them -- we're guessing that's important. Sounds cute, but how long until we can start printing whole people -- Weird Science, anyone?
Shapeways serves up prêt-à-imprimer 3D bones, Lagerfeld stands by for full skeletal replacement
3D printed chocolates? Sure, sounds innocuous enough. But made-to-order 3D printed bones? Now, that's just morbid. For the surgical team at Glasgow's Royal Hospital for Sick Children, however, the tech's come in handy as a budget-priced, pre-operative planning tool. Mark Frame, an orthopedic surgical trainee at RHSC, first came up with the idea to create the osteo-facsimiles after a costly university-made replica, commissioned for a procedure, failed to meet necessary proportion and size requirements. After undertaking a bit of self-assigned internet research, Frame sorted out a method to create renders of a patient's fractured forearm using CT scans processed via the open source OsiriX software. These were then passed through a separate MeshLab application to tidy up any artifacting, and finally exported in 3D-compatible .stl format. The resulting files were sent to Shapeways for printing, with the white plastic bone copies delivered just seven days later for £77. The hospital's been so pleased with the inexpensive outcome, that it's already begun prep work on a hip replacement surgery using a replicated pelvis -- and, no, they didn't specify if the patient was a fashion victim.
Visualized: Objet's 3D printer breathes plastic life into Hollywood creatures, layer by layer
It ain't easy being plastic, you know? Objet -- the 3D printing house that aimed to replace your office's all-in-one Epson back in July -- brought a few of its snazziest pieces here to SIGGRAPH, and we popped by to have a gander. Targeting the animation-inspired crowd that showed up here in Vancouver, the company brought along some Hollywood examples of how its multi-material Objet260 Connex helped movie makers craft prototype creatures before they were inserted into the storyline. Thor's Destroyer and Avatar's Na'vi were both on hand, as well as the two critters shown above. The hothead on the right was crafted in around 18 hours (and subsequently painted), while the cool cat on the left was built in three fewer. Wildly enough, that fellow required no painting whatsoever; so long as you're cool with shades of grey, you can program your object to be colored from the outset. Oh, and as for his cost? Around $80 for the materials -- slightly more for the printer itself. %Gallery-130291%
3D-printed Mario Kart turtle shells race to rescue American economy
As soon as you see these little RC Koopa shells, you know that life can't be that bad. In fact, they've already had a hallelujah-inducing impact on the world of the 3D-printing genius who created them. Ten days ago, Michael Curry (aka Skimbal) was among America's 13.9 million unemployed, having been unceremoniously booted out of his ailing architect's firm. All he had was a $700 MakerBot printer to stop his hands from idling, but he made the most of it. MakerBot saw his stuff and were as bowled over as we are, so they just gave the guy a job. We're dusting off our Wii controllers and even those little plastic steering wheels in celebration.
