Tempest in a Teapot of idiots. You can legally or illegally buy or steal a gun 100 times faster than doing it on a "3D Printer."
No criminal would waste his time. Only a person who is super interested in being a designer would take the time and expense to do this an exercise.
Reliable guns need metals for critical parts to function reliably for any length of time and they need to be done to tolerances and surface finishes that RP printers can NOT accomplish.
