NASA’s 3D-printed Mars Habitat competition doles out prizes to concept habs

A multi-year NASA contest to design a 3D-printable Mars habitat using on-planet materials has just hit another milestone — and a handful of teams have taken home some cold, hard cash. This more laid-back phase had contestants designing their proposed habitat using architectural tools, with the five winners set to build scale models next year.

Technically this is the first phase of the third phase — the (actual) second phase took place last year and teams took home quite a bit of money.

The teams had to put together realistic 3D models of their proposed habitats, and not just in Blender or something. They used Building Information Modeling software that would require these things to be functional structures designed down to a particular level of detail — so you can’t just have 2D walls made of “material TBD,” and you have to take into account thickness from pressure sealing, air filtering elements, heating, etc.
