To be fair... You don't need 3D printers to do it.
You just need a CNC mill. Sure, the 3D printers are cheaper, but I know people that make their own AR-15s from scratch. Its not that difficult to make. Heck, someone made an AK-47 receiver and stock out of a SHOVEL.
The gun debate has always been pointless. As long as guns exist anywhere, they can be obtained and used by people wanting to do others' harm. The same can be said for drugs, bombs, and other such things. They aren't complex.
Back from the dead, I'm afraid.
