My dad and his friends used to go to the hardware store and by all the stuff they needed to build zip guns in the 1960s. (I'm assuming they didn't by the ammo at the hardware store).
So you don't need a 3d printer to build a gun.
You can't 3d print bullets but they can be cast. Casting lead is like bronze age technology. Casing your own bullets for a fire arm has existed as long as firearms have been around.
