Automated remote synthesis and production of mechanical parts from regolith has the potential to be absolutely huge.  Most the problems with establishing human colonies beyond earth are that they require the astronauts to either bring their shelter with them or construct it while living out of a rudimentary temporary shelter.  With this, a team of rovers could be sent in advance to build machines, living spaces, and other equipment that&#x27;s already in place for when the astronauts arrive.  It also solves concerns about radiation exposure since the rovers could potentially construct a buried&#x2F;underground living structure.
