I'm positive that homebrewers ARE doing this. Probably the easiest is
the tank of liquid
polymer that is scanned and polymerized by a laser, and then another mm
of liquid is
added, then repeat. (Although gallons of the polymer might be real
expensive.)

Ther are also systems with dust that is sifted over the part, and a
laser heats the dust
such that the grains cohere. Numerous parts from copiers and laser
printers might be
of use in this one.
