NASA engineers have developed the first full-scale, 3-D printed copper rocket engine part — a combustion chamber liner that operates at extreme temperatures and pressures.
“Building the first full-scale, copper rocket part with additive manufacturing is a milestone for aerospace 3-D printing,” said Steve Jurczyk, associate administrator for the Space Technology Mission Directorate at NASA Headquarters. “Additive manufacturing is one of many technologies we are embracing to help us continue our journey to Mars and even sustain explorers living on the Red Planet,” said Jurczyk. Numerous complex parts made of many different materials are assembled to make engines that provide the thrust that powers rockets.
