3D printer extrudes molten glass to produce objets d'art

The list of materials capable of being extruded through a 3D printer seems to grow by the week, moving well beyond plastics, food and metals to now include another unlikely substance: glass. And while previous 3D printing methods have used powdered glass and silica sand, a team of researchers led by Neri Oxman out of MIT’s Mediated Matter Group has developed a 3D printer that extrudes molten glass.Read More

NASA tests 3D-printed turbopump

NASA has previously tested simple 3D-printed rocket components, such as combustion chambers and fuel injectors, but if the technique is to be practical, it has to cope with more complex items. Case in point is this 3D-printed rocket engine turbopump. Successfully built and tested at NASA's Marshall Space Flight Center in Huntsville, Alabama, the turbopump is described as "one of the most complex, 3D-printed rocket engine parts ever made."Read More

MultiFab mixes and matches 10 different materials in a single 3D print

3D printers may have come on in leaps and bounds in recent years, but most are one trick ponies in that their computer-controlled syringes extrude only one material at a time to build up an object. It's a process that's slow, imprecise, and often requires items to be printed in separate pieces and then assembled. MIT's Computer Science and Artificial Intelligence Lab's (CSAIL) MutliFab printer takes 3D printing technology a step further by combining 3D optical scanning with the ability to print using 10 different materials on the same job.Read More

3D printing in the vacuum of outer space

Last November, California-based Made in Space grabbed headlines when one of its specially-designed 3D printers became the first such device to print an object in outer space ... that was within the protective confines of the International Space Station, however. Now, the company is working on a printer that will work outside the station, in the cold vacuum of actual outer space.Read More

Approved by the FDA, 3D-printed drug set to change future of medication

The term "designer drug" may soon refer less to the illicit kind and more to custom creations by the pharmaceutical industry. Aprecia Pharmaceuticals Company has just had its proprietary ZipDose Technology platform approved by the US Food and Drug Administration (FDA). This marks the very first instance that the FDA has given the green light for a 3D-printed drug product.Read More

UC Berkeley's smart cap can detect spoiled milk

Researchers at UC Berkeley and Taiwan's National Chio Tung University have created a low-cost electronic sensor that's able to wirelessly monitor the freshness of milk. The team created the electronic components for the sensor using a 3D-printing method, which it believes could have a big impact on the industry.

3D-printed semi-soft robot jumps using butane power

Some robots are hard and some are soft, but in nature soft and hard structures are commonly mixed. In an effort to emulate this, engineers from Harvard University and the University of California, San Diego, have used multimaterial 3D-printing to create a combustion-powered jumping robot that transitions from a rigid core to a soft exterior.Read More
