New technologies such as 3D bioprinting promise to offer a laundry list of new treatments, drug discovery, and cures within the medical industry. With that said, we have been hearing promises for years that 3D printing will change the face of medicine. Despite these promises, bioprinting has yet to make any major impact within the market. Today things may have just changed! San Diego-based 3D bioprinting company Organovo (NYSE MKT: ONVO) has today announced the full commercial availability of their exVive3D Human Liver Tissue for preclinical drug discovery testing. The tissue, which is created via an in-house 3D printer, could...

One of the obstacles to jumping headlong into the additive manufacturing milieu for many people is often the expense of the 3D printer itself. Further, for those intrepid, budding engineers, designers, makers, and artists, an initial foray might more reasonably and affordably involve logo-instructables-01using a less expensive and complex machine. Enter one Instructables contributor, “mikelllc,” who has designed a make-it-yourself 3D printer that is constructed largely from recycled electronic components. Currently, only about 12.5% of all electronic waste, or “e-waste,” is recycled. Instead, the majority of cast-off electronic products — around 20 to 50 million metric tons per year worldwide...

“Makers, make love, not war.” This appears to be the best way to summarize UPS’s 3D printing service guidelines. UPS has been offering 3D printing services for a little while, but of course, these services come with a strict set of guidelines about what they will and won’t print for you. Naturally, just like going through airport security, weapons are at the top of the list of no-no’s. Anything gun or gun part related and anything that can be used in the “design, development, manufacture, testing, construction, operation, or maintenance” of nuclear weapons, missile or rocket systems, unmanned air vehicles,...

You can use 3D printing to make a handful of electronics, such as antennas and batteries, but LEDs and semiconductors have been elusive; you usually need some other manufacturing technique to make them work, which limits what they can do and where they'll fit. A team of Princeton researchers recently solved this problem, however. They've found a way to make quantum dot LEDs (and thus semiconductors) using only a 3D printer. The scientists choose printable electrodes, polymers and semiconductors, which are dissolved in solvents to keep them from damaging underlying layers during the printing process; after that, the team uses...

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...

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...

Drone proponents prefer using the term Unmanned Aerial Vehicle (UAV) or UAS for Unmanned Aerial System (latter term includes the entirety of the flying vehicle and the ground-base communications connection connecting the two). Whatever your preferred verbiage is, drones are poised to become a huge global business and the aerial devices are going to have a significant impact across a wide variety of industries. Historically, the military has been the biggest user/purchaser of drones; The Wall Street Journal estimated that the U.S. military spent about $3 billion on drone programs in 2012. And many aerospace companies continue to develop highly...

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...

Scientists and engineers at BAE Systems have released some interesting details about some futuristic technologies that could be operative by 2040. Or earlier. BAE Systems has been studying futuristic aircraft shapes for quite some time. The projects the British Defense company is working on were recently unveiled through a series of animations which show how civil and military aviation of the future could be based on 3D printers capable to print UAVs on-the-fly during a mission; aircraft that can heal themselves; a Transformer long range aircraft which splits into a number of smaller aircraft when it reaches its target, and...

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...
