  1. The really scary thing about 3D guns is that they don't have to be made out of metal. The blueprints currently online contain one metal piece so the gun can be picked up on metal detectors, but you know that someone somewhere is going to modify the blueprints so they don't have to use metal at all. Then metal detectors won't be able to stop these guns.

  2. That's great news, then! As long as they still need some metal.
