One of the things that have prevented 3D printed guns from gaining popularity with the mainstream is the fact that they can't fire more than several rounds without wearing out. The plastic used to make the body of the gun is simply too fragile to accommodate the force of firing. A 25-year-old machinist has found an easy, although time-consuming, way to solve this problem. Michael Crumling has developed ammunition he calls .314 Atlas, after the .314-inch caliber and the Atlas lathe he used to make his bullets. Each bullet designed by Crumling is buried deep inside and reinforced with a...

When was the last time you used your computer's disc drive? What about your DVD player? E-waste is all around us, but as the brilliant Instructables user behind this $60 3D printer proves, there's plenty to be done with it—if you've got some engineering chops. Last week we wrote about the world's smallest 3D printer, which costs less than $300 and prints resin. But an Instructables user named Mikelllc has gone way further, uploading his designs for a 3D printer made from 80 percent recycled e-waste and costing roughly $60. Part of the idea, he writes, is to "help us...

If you want a reason to opt out of school, you’re not alone. And Angad Daryani might just be the inspiration you were looking for. Daryani, a 16-year-old Mumbaiker, quit school in the 9th grade, frustrated by rote learning. Soon after, he built India’s first 3D printer (and possibly the world’s cheapest 3D printer). In 2013, he developed an “eye-pad” for the blind with MIT. When he was younger, he set up a miniature solar-powered boat and created an automatic watering system for garden plants. He has a longer list of hobbies that you can see here. He calls himself...

French designers alter 3D printer to let you ink yourself 3D printing technology has now followed the curve of most emerging inventions. What starts as a prototype gets picked up by the industries the idea most impacts, then by corollary industries, then by the art and hobbyist crowd. This month, Paris design studio Appropriate Audiences made that final step by hacking a 3D printer and turning it into a tattoo gun. The printing device itself, called Tatoue, affixes a tattoo gun on rails to a square metal frame. The frame and gun can move on three axes so the tattooing...

Yoshitomo Imura has become 3D printing's first martyr.  He was sentenced to two years in prison for designing and producing blank firing guns on a 3D printer.   From the-japan-news.com: YOKOHAMA (Jiji Press) — The Yokohama District Court sentenced a former Japanese college employee on Monday to two years in prison for producing guns with a three-dimensional printer. I have not seen that any of the guns actually fired a projectile; the only ones that I have seen on videos fired blanks.   Imura stated that he did not believe that he was violating the law.   Building blank firing...

In yet another move which may send shivers down the spines of law enforcement agencies around the world, while at the same time exciting techies and firearm advocates, Solid Concepts has revealed yet another 3D printed metal gun. Just under a year ago, the company, which has since been acquired by 3D printing giant Stratasys, revealed the world’s very first 3D printed metal handgun, the 1911. Although there had been a number of interesting plastic firearms 3D printed up until that time, this metal firearm was the first capable of shooting several rounds of ammunition flawlessly. In fact the original...

Health professionals who treat burn victims are acutely aware of the necessity to treat burn injuries, particularly severe ones, as rapidly as possible. As one journal article explains it, “In severe burn injuries where both the epidermal and dermal layers of skin are destroyed, prompt wound closure is critical for favourable [sic] patient outcomes and reduced mortality rates.” A team of biomedical and mechanical engineering graduate students at the University of Toronto have developed what may at the least be considered a preliminary–but certainly extremely technologically advanced–solution to the problem of critical, temporal health intervention for burn patients. For their...

While we have seen so many incredible life-changing applications for 3D printing, there are still many concerns which remain on the table when dealing with the possible negative implications of the technology. Whether you believe that the ease in which practically anyone will eventually be able to fabricate a firearm is a good or bad thing, just the thought of 3D printed firearms will send shivers down the spines of law enforcement agencies around the world. There has been an incredibly fast progression of the technology behind the methods of manufacturing guns with 3D printers in the last two years...

There are two 3D printing technologies that are capable of producing products that are almost indistinguishable from those created using traditional manufacturing techniques. These would be Selective Laser Sintering (SLS), and Polymer Jetting technology. The former is widely used by 3D Systems in their industrial level machines, which can cost in the $500,000+ range. The latter is currently used by Stratasys in their patented PolyJet technology, which is utilized in most of their industrial level 3D printers. These printers also cost in the 6-figure-plus range. While these 3D printing technologies are some of the best out there, the price tags...

Tungsten is an extremely hard, robust rare metal that has the highest melting point of all the elements, at 3422 °C (6192 °F). It also has a density that is 19.3 times that of water and about 1.7 times that of lead, which makes it comparable to uranium and gold. And now, a Philips-owned company is 3D printing it. Netherlands-based Smit Röntgen, a medical imaging parts manufacturer, has used Direct Metal Laser Sintering to 3D print tungsten parts. The company began researching the potential of 3D printing tungsten as a business opportunity over a decade ago and announced on Monday...

3D castle printed by Andrey Rudenko in Shorewood, Minnesota as seen at the end of August 2014. The castle is about 3.5 metres high.People have used 3D printers to print everything from medical devices to guns. But one Minnesota man is hoping to take this new technology to the next level and print a house. Andrey Rudenko, of Shorewood, Min., plans for the house to be about 10 metres by 20 metres. If it is two storeys, it will be about 3,600 square feet. And he is hoping to print the entire house in about a week. It would be...

Building site of the first ever 3D printed estate in Gardiner, New York. New York City architect/contractor Adam Kushner begins construction of the first ever 3D printed estate, which features a 3D printed swimming pool, 4-bedroom, 2400 square foot home, and more. The 3D printer which will be a modified version of Enrico DiniÂ’s D-shape printer, will, if all goes as planned, eventually be able to automatically place rebar within the 3D printed house, as it prints. We have covered a lot of news concerning the 3D printing of houses, over the course of the last year or so. Whether...

When will 3D Printers be able to build electronic devices from the ground up? ThatÂ’s a question many within the 3D printing space have been pondering for some time. Some experts feel as though it is only a decade away, while others think it could be a lot longer. Without a doubt, when this happens, it will change the world in ways that we could never imagine. Close your eyes and think about all the electronic devices that you use on a daily basis. There are smartphones, TVs, PCs, home lighting, automobile key fobs, and the list goes on. Now...

CNC firm’s 3D printing adapter to combine additive and subtractive processes in one machine. CNC machine maker, Hurco, announced that it recently filed a U.S. patent application for a new technology that combines 3D printing and CNC machining. According to the company, it has developed an additive manufacturing adapter that will allow Hurco machines to 3D print directly. “We designed an additive manufacturing adapter that, in combination with proprietary Hurco control software, effectively turns a CNC milling machine into a 3D printer,” said Gregory Volovic, President of Hurco Companies, Inc. “With this new additive manufacturing capability, users may go from...

Metal 3D printing is the Holy Grail of additive manufacturing. Unlike with other materials that can be printed, metal enables manufacturers to create end-use objects via 3D printing, objects which oftentimes outperform matter-1those produced with traditional casting techniques. In fact General Electric and Airbus are already saving money money using metal laser sintering machines to produce parts for anything from aircraft, to fuel nozzles. Additionally, once those products are installed for end-use, they continue to save money because of their light weight, great strength, and precise fit. The reductions of just a few kilograms on board an aircraft can save...

When 3D printing is discussed, one of the most debated topics is that of 3D printed weaponry, specifically guns. Last year, Solid Concepts created a 3D Printed replica of a 1911 pistol. At the time, it brought up quite a bit of debate, as the 3D printing of guns could severely undermine national and world-wide security. If anyone with a 3D printer could print an operational gun, then what good are laws that prevent people from obtaining guns? TodayÂ’s consumer level 3D printers can, for the most part, only print in plastic or plastic-like materials. Many people argue that guns...

A gunmaker who calls himself Buck O’Fama (get it?) has posted an video of his 3D printed Ruger Charger receiver. This single part, which usually holds the serial number and is an integral part of the firing mechanism, is, technically, the only part that defines a weapon as an actual gun. By printing his (or her) own, O’Fama has essentially skirted the law that requires all firearms to be registered with the federal government. Unlike the 3D printed Liberator, this 3D-printed part requires very little structural support and is simply used to guide the mechanism while firing. In other...

The number one issue that people have with 3D printers today, is the speed at which they print at. People now-a-days want things quickly, at the touch of a button. Over the years, many of our everyday jobs, chores, and desires have reached a point of almost becoming instant. For example, when you want to print a document from your computer or tablet, its done in approximately 5-10 seconds. When you want to bring up a website on your smartphone, itÂ’s up in a matter of 1-2 seconds. Just about every aspect of our lives, when compared to that of...

“Bigger is better,” as the old adage goes. When it comes to a juicy steak, or a diamond ring, these words always hold true. When it comes to 3D printing, however, there still remains some debate. The 2nd World 3D Printing Technology Expo was held in Qingdao, Shandong, China this past week (June 19-22). It featured thousands of individuals from China, United States, Germany, Belgium, the United Kingdom, and almost a dozen other countries. They were there to discuss the latest breakthroughs in 3D Printing, including possible applications, material use, business models and more. Qingdao Unique Products Develop Co., Ltd,...

When it comes to 3D printers, they can be used to make all sorts of objects, via additive manufacturing. However, many ‘makers’ (people who utilize their creative abilities to ‘make’ things) use more than just 3D printers when trying to visualize their ideas in creating tangible objects. CNC machining, as well as laser engravers are used by many individuals in creating complete products, made from a multitude of materials and processes. One problem with this, is that all of these processes currently require individual machinery. For example, many ‘makers’ end up needing to purchase, store, and operate a 3D printer,...
