Researchers 3D print ultra-strong steel parts from powder
Soldiers needing replacement parts may turn to 3-D printers in the future to rapidly deliver reliable and ultra-strong metal parts. Army researchers are looking at new technologies to create steel alloy parts from powder using a laser. At the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory, materials manufacturing scientists say this technology may change everything.
“I think it’s going to really revolutionize logistics,” said Dr. Brandon McWilliams, a team lead in the lab’s manufacturing science and technology branch. “Additive manufacturing is going to have a huge impact on sustainment.” While progress remains steady, McWilliams said realizing the dream of quickly printed, reliable 3-D metal parts is still a long way off; however its benefits will be substantial.
