Plastic is too weak to resist the high explosive pressure more than for a couple of rounds. Best gun material for high pressure parts and the crucial loading mechanism is steel or titanium. Only artificial material strong enough might be carbon fiber with the fibers correctly oriented to resist tensile stress. Firing a plastic gun, a gun that has its barrel or loading mechanism made of plastic,  is highly risky.

One day soon Less it will not only be plastic that is used through 3-D printers. Already they are working on organic 3-D printers for creating organs. They have been successful in getting the genetic material and blood to combine and grow. How long will it be before a new material is made to use in these printers that is stronger than plastic and liquified at low enough temperature to go through a 3-D printer? Since we are years behind what the government is privy to it would not surprise me if that material does not already exist. Just a thought.

Quite true. Who knows what's cooking in the secret laboratories.

Impressive. Who knows what the metal printers cost in a couple of years.
