Video of 3D printing at JPL
This video clip shows a 3D printing technique where a printer head scans over each layer of a part, blowing metal powder that 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.
NASA's Jet Propulsion Laboratory in Southern California built and will manage operations of the Mars 2020 Perseverance rover for NASA.
