Earth-orbiting lasers would be cheaper. No losses due to scattering by air.

They'd likely be operated in a spun environment if in space.

I wonder if the moon's light gravity would be sufficient, or if they'd have to slow things down considerably to allow 3D printer work on the surface.

Electrostatic attraction would probably take care of that problem: negative charge on the substrate, positive charge on the particles...

Right. So you don't build, you excavate. Do the foundation work here, then send up the plumbing, electrical, and trim crews.
