It would make sense.

I work a lot with 3D Printing.

Laser sintered metal technology and plasma spray depositing has changed the game in many ways. Metal parts can be made reasonably quick and dependable. There is a guy who 3D Printed a 45 caliber Colt 1911 pistol and has shot thousands of rounds through it dependably. Rocket nozzles are another item being made with 3D printing.

I see many parts we can not fathom being made now, 3D Printable in a few years. Hemi Blocks in your basement anyone?
