Please throw me a link to a machine that will print in metal suitable for a gun that will not self destruct on the first shot.

It seems that 3d metal printing a 100x more expensive than conventional manufacture. 30 years from now who knows?

For printing something that one can buy in a store, additive manufacturing will almost always be more expensive than the mass produced part. However, if they go around banning things, then suddenly the economics gets better, because available but expensive is better than unavailable.

If they start making models for drug accessories as well as weapons, then half the people in America will buy one.
