Most infrastructure could be build entirely by robots. A really big issue with lunar landing sites is the debris kicked up by landing and take off. Berms would have to be built up around settlements. Fortunately, lunar regolith can be sintered with microwave radiation, effectively creating what resembles volcanic glass.
Throw in the fact that refining and 3d printing metals on the moon is pretty easy due to the free vacuum, and you can built nearly everything before humans have to get there.
- moftz 8y ago3D printing has some issues in a vacuum. Normal plastic will outgas and any voids can literally blow a hole in the filament. If you bring the right equipment, you can make lunar concrete with processed lunar rocks as the cement and the dust as aggregate. You could build sound structures out of this with inflatable liners so you can actually live in there. Gravity is 1/6th so the buildings don't have to be as strong as they do here on earth. However, you do need to keep the concrete warm which makes things harder.
