By now you’ve probably heard the hullabaloo around 3D printed guns, but NASA is cranking up the heat even more with its laser 3D printed rocket parts, as noted by Ars Technica.

NASA’s Marshall Space Flight Center recently completed a successful test of a rocket injector part. Printed using a technique called direct metal laser sintering, the injector flawlessly withstood pressure of 1,400 pounds per square inch and 6,000 degrees fahrenheit.
