    How does the chamber last? I can’t imagine that it would last more than a couple shots, even if using a small calibre and special filament.

    Also, how does the firing pin make a spark if it’s made out of plastic?

      You print them in carbon fibre or a metal polymer alloy, the barrel, sear and pin are all metal. Many modern firearms are injection Molded polymers, the only difference with 3d printed guns is the structural rigidity of the frame due to the layer lines

        So the parts that need to be all metal can’t be printed at home then. I’ve never heard of a consumer level laser metal sintering machine.
