3D printers are cool for printing miniature Yoda heads, tiny owls, and little tea cups. But what about printing something really useful, like, say, a stainless steel rocket engine?

Check out this project from Rocket Moonlighting. Says Hack-a-Day:

Most any rocket engine you’d find on a spacecraft – save for solid or hybrid rockets – use an engine system that’s fairly complex. Because of the intense heat, the fuel is circulated around the chamber before ignition giving a motor its regeneratively cooled nomenclature. This arrangement leads to a few complicated welding and machining processes, but surprisingly these obstacles can be overcome by simply printing a rocket engine on a 3D printer.
