That's amazing. Also that's a HUGE metal print. It must have taken a month to print. Even tiny dinky little things like keychains take all night.

Funny story, I know a guy who used to run a big industrial 3D metal printer. They use fine metal powder, which is an inhalation hazard, so you have to wear a breathing apparatus that attaches to your belt. He was working and nobody was around, so he let out a big fart. The intake for the breathing apparatus was right over his bunghole, and it sucked the whole fart right into his face.
