Marshall Center engineers Jim Lydon, left, and Zach Jones work on a recently 3-D printed rocket part. Selective laser melting, a 3-D printing process, is being used to make some of the parts more efficiently and affordably — without compromising performance and safety — for the RS-25 engine and other components of NASA’s Space Launch System rocket.
