Don't believe what you hear on the radio. It's getting as bad as TV.
3-D printers are in their infancy, and while interesting are so far limited to materials which can flow through a nozzle. I've thought of them as being possibly useful for making something like replacement aperture blades and other non-stressed parts.(Shutter blades need to be made of metal.)

But making guns? That's laughable. Real guns are made of wood and steel, which do not flow well through a nozzle. Jp498 has it about right.
