These 3D printers use ABS plastic to make the bits. I assume that they are making stuff which isn't going to bend or shatter as the models only have 30% the strength of injection moulded bits ..certainly not the firing mechanism or barrels...I'd not want to be within 50 yards of a fully plastic one being fired unless I were stood behind a brick wall.
glad someone spotted this before me.
hell the standard 3d printer stuff could be used for shrouds etc, but i wouldn't make a receiver out of abs. ye gods i'd be at least 100 yards away and behind sandbags before that was tested.
reminds me of the old jolly roger cookbook (now considered a terrorist handbook).
"To make plastic explosive start by boiling bleach until the white fumes stop..."
if you're stupid enough to do this you deserve whatever happens to you. same with a "printed" gun.
when they can 3d print metal i'll worry.
