At the University of Toronto, a 3D-printed gun has been printed. It isn’t functioning yet because its makers are abiding by Canadian gun laws, but they can easily modify it to shoot.
The lab in Toronto downloaded the American 3D-printed gun design the first day that Cody Wilson of Texas put them online, altered it so it couldn’t shoot, and printed the parts there.
What will the gun laws everywhere turn into once printing your own gun is a reality? How will authorities trace 3D-printed bullets, and how will security everywhere detect plastic firearms?
