NASA's Perseverance Rover Bringing 3D-Printed Metal Parts to Mars

This video clip shows a 3D printing technique where a printer head scans over each layer of a part, blowing metal powder which is melted by a laser. It's one of several ways parts are 3D printed at NASA's Jet Propulsion Laboratory, but was not used to create the parts aboard the Perseverance rover. Credits: NASA/JPL-Caltech
