live in a d0me. We can do the 3D printer thing like we plan on doing with mars. It'd have to be big though.. Nobody wants to live in a space as confined as the international space station for an extremely long period of time.
But since people are there and they have a 3D printer they can regularly make their settlement larger and larger. Using solar power and other renewable energies in order to provide electricity to do things like grow crops and invitro meat! Also, the base would likely need to be near the poles where the ice is; if it is drinkable.
Perhaps the colony could be made inside a volcano, as they haven't erupted for millions of years. That'd make it simpler in that you could just cover the mouth of a volcano and you'd be provided with a large and safe environment.
