First time accepted submitter Trep (366) writes "I thought Slashdot readers might be interested in seeing how my friend is slowly building a 3D printed toolbox. He's created a fully functional tape measure which is 3D printed as a single assembly, to follow up on his 3D printed dial calipers. This is a pretty novel design, with a lot of moving parts that come out of the printer completely assembled!"

It goes up, it goes down, it goes upside down and keeps on flying. We're talking about Curtis Youngblood's latest quadcopter prototype, but as his website says, "Curtis has been flying and competing with RC Helicopters since the early 1980s and is a Multi-time World Champion and Multi-time 3D Champion." This lucky dog has managed to turn his hobby into a business; he makes and sells radio controlled helicopters -- not the $60 ones from Harbor Freight, but sophisticated aerial beasts that can carry still and video cameras and could easily be used as short-range drones, except that these are hobbyists' toys -- for hobbyists who can afford to spend hundreds and even thousands of dollars, anyway. There are plenty of quadcopter kits on the market for lots less than Youngblood's creations, along with build-it-yourself guides. But these won't fly upside down. For that, you need variable-pitch rotors and sophisticated control systems. "But what about 3-D printing?" you ask. Of *course* you can use a 3-D printer to make a quadcopter. That was an inevitable development. Here are open source instructions for building one. Enjoy the ride!

An anonymous reader writes "Shubham Banerjee, a seventh grader in California, has developed a braille printer made from a $350 Lego Mindstorms EV3 kit and some simple hardware. He calls the science fair project the Braigo. 'The Braigo's controller is set up to scroll through the alphabet. You choose a letter and it prints it out with tactile bumps on a roll of calculator paper. The print head is actually a thumbtack, which Banerjee settled on after also testing a small drill bit and a mechanical pencil. The first prototype isn't terribly fast, but it proves the concept works. Banerjee is working on improvements that will allow it to print full pages of text.'"

An anonymous reader writes "Carpenter Richard van As shot to fame a year ago thanks to a 3D-printed prosthetic he developed to help him get back to work after an accident. A year later, RoboHand has helped hundreds of people who can't afford expensive prosthetics, and has been used all over the world. Now van As is back with RoboBeast — the 3D printer built to be extremely durable, designed specifically for taking RoboHand into conflict zones and areas of extreme poverty."

TAZ 3 is the fifth model in the LulzBot line of 3D printers by Aleph Objects, Inc. FSF has certified other models of LulzBot 3D printer for respecting privacy as well."

Lucas123 writes "In a report released today, Gartner predicts that the time is drawing near when 3D-bioprinted human organs will be readily available, an advance almost certain to spark a complex debate involving a variety of political, moral and financial interests. For example, some researchers are using cells from human and non-human organs to create stronger tissue, said Pete Basiliere, a Gartner research director. 'In this example, there was human amniotic fluid, canine smooth muscle cells, and bovine cells all being used. Some may feel those constructs are of concern,' he said. While regulations in the U.S. and Europe will mean human trials of 3D printed organs will likely take up to a decade, nations with less stringent standards will plow ahead with the technology. For example, last August, the Hangzhou Dianzi University in China announced it had invented the biomaterial 3D printer Regenovo, which printed a small working kidney that lasted four months. Apart from printing tissue, 3D printing may also threaten intellectual property rights. 'IP will be ignored and it will be impossible or impractical to enforce. Everything will change when you can make anything.' said John Hornick, an IP attorney."

cold fjord sends this news from Popular Mechanics: "[M]aking custom racecar parts out of carbon fiber is daunting. The only real method available is CNC machining, an expensive and difficult process that requires laying pieces by hand. To improve the process, [Gregory Mark] looked to 3D printing. But nothing on the market could print the material, and no available materials could print pieces strong enough for his purposes. So Mark devised his own solution: the MarkForged Mark One, the world's first carbon fiber 3D printer. Mark debuted his Boston area-based startup MarkForged at SolidWorks World 2014 in San Diego with a working prototype. The Mark One can print in carbon fiber, fiberglass, nylon and PLA (a thermoplastic). ... The main advantage of the Mark One: It can print parts 20 times stiffer and five times stronger than ABS, according to the company. It even has a higher strength-to-weight ratio than CNC-machined aluminum. ... Mark says that he imagines this machine is for anybody who wants to print in a material as strong as aluminum. Beyond racecars, it could be useful to industries like prosthetics."

Nerval's Lobster writes "Google remains tight-lipped about its roadmap for Google Glass, and its population of early-adopter 'Explorers' remains small. Nonetheless, a growing collection of engineers, designers, and artists are creating their own accessories and add-ons for Glass — some of them useful, others totally whimsical. For example, there's Brooklyn designer Todd Blatt, who's relying on a 3D printer to churn out Glass accessories such as tiny flower-pots and pencil holders (not so useful) as well as a plastic camera cover (useful, at least for anyone in the vicinity who likes their privacy). Small firms such as GPOP and Remotte are likewise exploring how to best skin, dangle, screw, and attach hardware to Glass that makes it operate in whole new ways. (The avenues for exploration have opened up with the second generation of Google Glass, which includes a small screw in the right arm that can double as a mounting point for new tech.) Google seems to have no choice but to let this growing ecosystem thrive, even if some of the modifications (such as camera covers) don't necessarily suit its interests. But will the company actually say something about it?"

An anonymous reader writes "Dell today announced a partnership with MakerBot to offer Replicator 3D printers and scanners to small and medium-sized businesses looking for faster and more affordable ways of prototyping.

Lucas123 writes "Stratysis today announced it will be shipping this year a printer that can use hundreds of colors and polymers to create production-grade or prototype objects without the need for assembly. Previously, manufacturers could print multi-colored parts using many different materials and assemble them after completion. Stratasis' Objet500 Connex3 Color Multi-material 3D Printer features a triple-jet printer head that combines droplets of three base materials to produce parts with virtually unlimited combinations of rigid, flexible and transparent color materials in a single print run."

3-D printing is far from new, but a $499 3-D printer is new enough to get a bunch of people to write about it, including someone whose headline read, CES 2014: Could 3D printing change the world? XYZPrinting, the company behind the da Vinci 1.0 printer, has some happy-looking executives in the wake of CES. They won an award, and their booth got lots of attention. This is what trade shows are all about for small and/or new companies. Now the XYZprinting people can go home and pump out some product -- assuming they got a lot of orders (and not just attention) at CES.

Slashdot visited the Formlabs CES display in 2013. Tim looked at their Stereolithgraphy 3-D printer again this year. The company is now boasting about their PreForm 1.0 software, and not as much about their hardware, which was their main focus last year. Another important difference was that at CES 2013 they couldn't talk about sales because they hadn't sold any units yet, but now they claim they've sold over 1000. And the last major problem they faced was a patent infringement suit, which seems to be settled (or nearly so). According to this Oct. 2013 article, it's doubtful that Formlabs would have been able to raise $2.95 million through Kickstarter, followed by another $19 million from traditional venture capitalists, if the lawsuit wasn't close to settlement -- which may not matter much in the long run, since many key patents in the field have either expired or are due to expire between now and 2015.

angry tapir writes "Adobe has rolled out an update to Photoshop that incorporates direct support for 3D printing. According to Adobe, they don't expect most users to directly create 3D meshes in Photoshop. Instead they expect most of the time people will import objects from other applications and then use Photoshop as a finishing tool to tweak and repair meshes — in a similar fashion to how Photoshop can be used to tweak photos before production. The application currently directly supports MakerBot printers and the online Shapeways service. More printer support is coming (printer profiles are editable XML files) and the application can also export STL files that can be copied to a USB drive and used on other brands of 3D printer."

Bennettt Haselton has a gift idea for this year that needn't necessarily cost you any money (if you have a color printer available), though as he points out there are ways to invest in a higher-quality result. The gift? A unique picture created with a few pieces of free software and a bit of your time. Bennett writes: "You can use these little-known free programs to create a photomosaic of a friend's wedding photo or other favorite photograph, for a uniquely personal gift that doesn't cost much but can still delight. Follow these steps to use the programs most effectively and get the best results." Read on for the rest.

hypnosec writes "Researchers have developed and open-sourced a low-cost 3D metal printer capable of printing metal tools and objects that can be build for under £1,000. A team of researchers led by Associate Professor Joshua Pearce at the Michigan Technological University developed the firmware and the plans for the printer and have made it available freely. The open source 3D printer is definitely a huge leap forward as the starting price of commercial counterparts is around £300,000. Pearce claimed that their technology will not only allow smaller companies and start-ups to build inexpensive prototypes, but it will allow other scientists and researchers to build tools and objects required for their research without having to shell out thousands, and could be used to print parts for machines such as windmills." It's a modified RepRap; looks like we're getting closer to the RepRap being able to print all of its parts.

A while ago you had the chance to ask gamer and console modder extraordinaire Ben Heck about his favorite mods, hacks, and what he sees coming in the future. Below you'll find his answers to your questions.

MojoKid writes "Motorola is forging ahead with the concept of modular, customizable smartphones first put forth by designer Dave Hakkens with his Phonebloks concept. The company said recently that it was officially pursuing such an idea with Project Ara, and Motorola is already putting together important partnerships to make it happen. 3D Systems, a maker of 3D printers and other related products, has signed on to create a 'continuous high-speed 3D printing production platform and fulfillment system' for it. In other words, 3D Systems is going to print parts for the project, and what's more, the company has what appears to be an exclusive agreement to make all the enclosures and modules for Project Ara."

Lucas123 writes "The ATF has been testing 3D printed guns over the past year and, not surprisingly, has found that depending on the thermoplastics, 3D printers and CAD designs used, some can explode on the first attempt to shoot them. The ATF published videos this week of the tests on YouTube showing what looked like a Liberator model of a 3D gun exploding upon being fired. Another model, created with the popular ABS polymer and an advanced printer, could fire as many as 8 shots. The tests were published at a time when a law passed in 1988 banning the sale of guns made entirely of plastic is set to expire next month." I hope they post the videos when they do the same tests on Solid Concepts' 1911.

Daniel_Stuckey writes "At the start of this year, President Obama nicely summed up the grandiose promise of 3D printing — or rather, the hype surrounding it. In his State of the Union address the president suggested the fledgling technology could save manufacturing by ushering in a second industrial revolution. That shout-out inspired a spate of buzzkill blog posts pointing out — rightly enough — that despite its potential, 3D printing is still in its infancy. It's not the panacea for the struggling economy we want it to be, at least not yet. Apparently the naysayers weren't enough to kill the 3D-printing dream, because, with support from the federal government, MakerBot announced its initiative to put a 3D printer in every school in America. The tech startup and the administration are betting big that teaching kids 3D printing is teaching them the skills they'll need as tomorrow's engineers, designers, and inventors." Caveat: Makerbot no longer produces open hardware, and they are pushing proprietary Autodesk software and educational materials as part of the free 3D printer. Makerbot also launched a call for open models of math manipulatives on Thingiverse (you might remember them from elementary school) so that teachers have something useful to print immediately.

Nerval's Lobster writes "Researchers have demonstrated a technique that produces inexpensive, functional electrical circuits that can be printed using about $300 worth of materials and equipment, including generic inkjet printers. The technique, developed by researchers from Georgia Tech, the University of Tokyo and Microsoft Research, allows circuits to be printed onto irregularly-shaped materials or almost anything able to go through the paper feed on a printer designed for consumers. The chief advantage of the technique is the ability to print circuits using silver nanoparticle ink rather than relying on the thermal-bonding technique called sintering, which is time-consuming and can destroy delicate base materials. Researchers were able to print new circuits in about 60 seconds on almost any material that could go through the printer, though resin-covered paper, PET film and glossy photo paper worked best, while sheets of canvas cloth and anything magnetic were ineffective. Once printed using silver ink on flexible base material, the circuits can be attached to existing hardware by simply laying or taping them in place and making connections using conductive tape or conductive glue. (Soldering would destroy the underlying material.)"
