An ice fab

*Fabricating with ice. It's one of those niche academic-lab schemes that might turn out be really handy somewhere sometime, like, say, on the surface of a Saturnian moon or something.

*Maybe fabricating giant pykrete battleships to feed a future Los Angeles with potable water. "You shipped us water?" "No man, the water *is* the ship."
