Modified laser cutter prints 3-D objects from powder (Video)

Rice University bioengineering researchers have modified a commercial-grade CO2 laser cutter to create OpenSLS, an open-source, selective laser sintering platform that can print intricate 3-D objects from powdered plastics and biomaterials. The system costs at least 40 times less than its commercial counterparts and allows researchers to work with their own specialized powdered materials.

3D Printed Ceramics Using Sound Waves, Created by Dutch Designers (Video)

Olivier van Herpt, like many artists, found himself dissatisfied with the artistic capabilities of traditional 3D printers and 3D printing materials. “When I first started researching 3D printing the technology was an exciting and interesting one,” the Dutch sculptor says. “But, the desktop 3D printers on offer were unable to produce things at a human… [read more]

NASA’s 3D Printed Rocket Engine Roars to Life (Video)

A NASA team moved a step closer to building a completely 3-D printed, high-performance rocket engine by manufacturing complex engine parts and test firing them together with cryogenic liquid hydrogen and oxygen to produce 20,000 pounds of thrust.
