NGC has a long history of developing and inserting additive manufacturing (AM) into production, for both manufacturing support and fly-away hardware. This presentation will cover NGC’s maturation of AM from the early 1990’s, where NGC won World Rapid Prototyping awards through today, discussing NGC’s developments in fly-away polymer and metallic products for air and space. The methodologies and approaches for defining, developing and qualifying AM technologies for production will be discussed. Business cases from multiple U.S. Department of Defense programs and various part complexities will be presented. Emerging additive manufacturing technologies will be discussed in the context of potential for flight hardware capability.
