3D printers makes things out of an epoxyputty looking stuff, or out of powder solidified with a laser (depending on what type).

Most 3D printers can duplicate themselves (minus the electronics), so I would just do that a bunch of times and share the 3D printing love!

I would make statues of myself in different poses and annoy people with it.

I would make more 3d printers to make more 3d printers to make MORE MONEY
and maybe some more food.

print myself a girlfriend.
