NASA's 3D Printed Habitat Challenge tasked citizen inventors to create viable, 3D printable structures, that people could potentially live in on Mars or the moon, out of recyclable materials and simulated Martian soil. The first of three challenge phases, focused on design, finished in September of 2015, and Phase Two, with an emphasis on materials and recycling, was launched this past October. The second phase of the 3D Printed Habitat Challenge, the Structural Member Competition, focuses on the material technologies that are necessary to 3D print structural components, and is broken down into three sub-levels. Level One ended in March, and the winners were announced in May, with $100,000 awarded to the top two teams. Level Two began shortly after, and participants were required 3D print a structural beam for bend testing. NASA has just announced the winners of this level, and awarded over $200,000 to the winning teams. Read more at 3DPrint.com: http://3dprint.com/180698/nasa-3dp-h...ase-2-level-2/
