NASA develops LWDC 3D printing process for rapid fabrication of rocket engine nozzles

Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama have developed and tested a new additive manufacturing technique called Laser Wire Direct Closeout (LWDC). The 3D printing method can be used to make rocket engine nozzles at a reduced cost in a shorter time.

We’ve kept a close eye on its partially 3D printed RS-25 rocket engines for the Space Launch System, while its more out-there 3D printing […]
