There are so many big words in this video to make things sound extra expensive but don't worry as a taxpayer you ARE paying for it.

I have a feeling US military supply contractors are not too concerned about this technology hurting their bottom line.

Including grenades and targets?

Heard about 3-D printing gun powder ....?

Don't laugh, there's a company that has a machine that can 3D print pizza into any shape you like.

( I saw a purposely vague video about the machine, so it must be true.)
