In an attempt to build dwellings on Mars, Russian architects, ZA, have proposed a series of robots that would identify weak areas in the Martian soil, carve them out, and then, using a process similar to that of structural 3D printing, create interior structures using the leftover soil on Mars. Similarly, the European Space Agency has studied the feasibility of bringing 3D printers to the Moon, where they could be used to print shelters for the first semi-permanent inhabitants.
