The European Space Agency is contemplating 3D printed moon-bases
By using the Moon’s loose rocks as a base for making concrete printing material, a 3-D printer will be able to build up a structure that uses local materials to create buildings. The idea is that with a shell made of moon rocks to act as a shield against micro-meteors and similar hazards, the living quarters for moon colonists could be inflatable envelopes protected by these shells.
