3D Printing is awesome for small-scale manufacturing. But plastic is VERY limiting.

Metal printing is a thing, but it's protected by so many trade secrets, patents, etc. that it's effectively out of reach for us.

Except, it doesn't have to be so hard! Plenty of metals can be suspended in a binder, printed, and fired at ceramics-kiln temperatures (although gas purge and better control may be required). But binder/material specifics are locked away from us.
