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

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

Aluminum "yolk" nanoparticles deliver high-capacity battery recipe

Researchers at MIT and Tsinghua University in China have found a way to more than triple the capacity of the anodes, or negative electrodes, of lithium-ion batteries while also extending their lifetime and potentially allowing for faster battery charging and discharging. The new electrode, which makes use of aluminum/titanium "yolk-and-shell" nanoparticles, is reportedly simple to manufacture and is especially promising for high-power applications.Read More

Beerbots demonstrate robotic collaboration by serving drinks in a makeshift bar

Staffing bars and restaurants with machines sure sounds convenient, but getting them to collaborate smoothly in such a frenzied environment poses significant hurdles. Their ability to interact with one another and the world around them is just not quite at the level of your typical wait staff. But MIT researchers have made an impressive advance in this area, showcasing a team of three robots that work together to deliver beer, suggesting the technology responsible could translate to cooperative robotic systems for not only bars and restaurants, but hospitals and disaster situations.Read More
