Engineers at MIT have developed a way to use plant cellulose as a feedstock for 3D printers, providing another renewable, biodegradable alternative to popular petroleum-based polymers like ABS currently being used. It could also be cheaper, stronger, and offer antimicrobial properties.
3D-printing firm Apis Cor recently showed off its own portable 3D printer by using it to build a basic tiny home. The total cost for the project came in at just US$10,134, not including furniture or appliances.
The US Army’s Armament Research, Development and Engineering Center (ARDEC) has successfully fired the first 3D-printed grenade from a 3D-printed grenade launcher called RAMBO (Rapid Additively Manufactured Ballistics Ordnance).
3D printed objects do tend to have a low-res look to them. This is because there are grooves visible between the deposited layers of material. While there are methods of smoothing down the ridges on either side of those grooves, scientists have developed a technique that they say is superior.
Near micron resolution printing of glass
NASA is getting into the textile business thanks to a team at the Jet Propulsion Laboratory in Pasadena, California. The team has unveiled prototype swatches of a new metallic “space fabric” created using 3D printing that incorporates advanced functions that would be beneficial for use in space.
A new construction principle has let researchers create load-bearing 4D-printed objects. They could be useful for medical devices like stents or aerospace.
