3D Printing

Although 3D printing technology has progressed in leaps and bounds in recent years, most printers are still only capable of printing a solid object out of a single material. That's fine if you want to produce a plastic object with the same density throughout, but what if you want to use multiple materials in the one object or alter its internal architecture to vary its density and therefore its flexibility? A team at MIT's Computer Science and Artificial Intelligence Lab (CSAIL) has developed a new software pipeline that makes both these things possible.  Read More

A new micro-printing process that allows the production of biocompatible and energy-effici...

The miniaturization of electronics continues to revolutionize the medical industry with tiny, swallowable devices and minuscule, implanted sensors. Researchers at Tel Aviv University (TAU) have kept the ball rolling with the development of a new micro-printing process that allows the production of flexible and energy-efficient microelectromechanical (MEMS) devices that can be safely used in the human body.  Read More

The BLOODHOUND SSC hopes to reach speeds of more than 1,000 mph (1,610 km/h) in 2015 with ...

The Bloodhound Supersonic Car (SSC) team from the UK is continuing its journey towards claiming the world land speed record. After testing its rocket engine last year, the team has turned to 3D printing technology for another critical part of the high speed vehicle – a tip that, if all goes well, will be the first part of the car to break through the 1,000 mph (1,610 km/h) mark in 2015.  Read More

Easton LaChappelle demonstrates his prosthetic arm to President Barack Obama at the third ...

Advanced prosthetics have come a long way in the last few years, but the costs have also skyrocketed. A cheaper alternative may be on its way thanks to Easton LaChappelle, a 17-year old high school student from Colorado, who is using free online resources and the boom in inexpensive 3D printers to develop a functional prosthetic arm and hand. His projects have already earned him an invitation to the White House, and he's now working at NASA on the Robonaut team.  Read More

Volumental's vision is to be able to 3D print more or less anything you can see

Scanning and 3D printing an object could become much simpler if 3D printing company Volumental is successful in crowdfunding the development of a web app which would allow users to scan and print 3D objects using nothing more than a Kinect sensor and a web browser.  Read More

Nature has been the source of inspiration for a variety of different forms of robotic locomotion. Yet another example is the STAR, a 3D-printed robot modeled after an insect's ability to squeeze into even the tiniest spaces. Developed by students at UC Berkeley's Biomimetic Millisystems Lab the STAR, which stands for Sprawl Tuned Autonomous Robot, is able to flatten its legs down to slip under a small gap and then raise them up again to climb over larger obstacles.  Read More

Ivan Sentch plans on harvesting bits and pieces from a 1993 Nissan Skyline GTS for the eng...

While many Solidoodlers will likely use their 3D printers to output Yodas, gearsets or bunnies, one New Zealander decided to take 3D modeling to the next level. With the average price of an Aston Martin DB4 running in the hundreds of thousands of dollars, Ivan Sentch decided to go one better by printing a full-scale Aston Martin DB4 replica.  Read More

Michigan-based Sintercore is billing its Auxetik as the first commercial 3D printed firearm muzzle brake. Made of Inconel alloy using a laser additive manufacturing process, the Auxetik is designed to tame the recoil and muzzle rise of AR-15 pistols.  Read More

The 3D printed Haptic Feedback Shift Knob and internal workings

Harnessing the power of Ford’s open-source platform OpenXC, 3D printing, Bluetooth and a Xbox 360, one of the Detroit automobile manufacturer’s engineers has created a manual shift gear knob that vibrates (haptic feedback) at the optimum time for a gear change.  Read More

A six-axes robotic arm allows the printer to follow 3D vector-based toolpaths

The additive layer process of conventional 3D printers means they are usually limited to bottom up fabrication on three axes. The Mataerial printer managed to defy gravity by using a quick-solidifying print material, but now the LA-based NSTRMNT team led by Brian Harms, a Masters student at the Southern California Institute of Architecture, has created a 3D printing process called suspended disposition that gets around gravity by printing objects within a gel. Not only does this allow freeform additive fabrication on six axes, it also enables an "undo" function.  Read More
