Not in rapid succession. We do this with mortar rounds and PVC - you can fire once an hour because they swell. Swollen barrels jam. Jammed bullets blow up barrels. Thermoplastics suck ass for any sort of kinetic task. 3D printing could use thermosets, but they also suck ass for any kinetic task. Thing of it is, barrels are easy to make. You don't need a 3d printer to make a gun - you need a piece of pipe and a nail. Which should scare you more than some goofus with a makerbot.
