> Why not? Because nobody is printing guns!

People are printing guns. They're printing guns right here in the UK.

Then they're taking them out to the firing range, setting them up on a test stand, firing them by remote control, and filming the ensuing carnage with high frame rate cameras.

If you make a really really good 3D printed gun, it'll last at least two shots before it explodes into about a trillion razor-sharp fragments expanding rapidly outwards from where your hand used to be. The way you tell it's a really really good one is it didn't explode into a trillion fragments on the first shot.

We've seen enough Terrifying Public Information Films about the dangers of fireworks to mess with that shit.
