About the presentation
This presentation focuses on large metal part additive manufacturing with newly developed multi-nozzle directed energy deposition (DED) manufacturing technology. Recent advances in technology now make large part printing economically feasible and technically superior. The presentation showcases the additive manufacturing of NASA’s RS-25 engine nozzle liner. This part is 111″ tall, has a 96″ base diameter, and weighs about 4,100 lbs. The build approach of this liner is discussed to highlight various challenges to large part printing and strategies adopted to mitigate these challenges. The goal of the presentation is to bring awareness to the advancement of metal additive manufacturing (AM). This is achieved by demonstrating the ability to print large complex parts with difficult materials while targeting critical industry applications. At the same time, the presentation aims to educate attendees of the various challenges presented by large-scale printing, and how industry partners are working together to solve these problems. Last but not the least, the presentation shows how various industry teams came together with government agencies to advance existing technologies and develop new ones to solve difficult manufacturing challenges and advance metal AM to a new level of manufacturing.
