The US Army has been exploring additively manufactured (AM) energetic formulations over recent years with the key benefits being safer energetic material handling and improved ballistic performance. Department of Defense (DoD) researchers are examining where three dimensional printing (3DP) and energetic materials overlap in the fields of gun propulsion, explosives and pyrotechnics. Innovative 3DP formulations incorporating legacy energetic materials and novel energetic 3DP molecules are candidates for improving overall system performance and optimizing for lethality and accuracy demonstrating the US Army’s commitment to performance for future capability growth. A synergy between formulation and printing technique has led to understanding the design space for gun propellant stereolithography apparatus (SLA) and digital light processing (DLP) printing which involves understanding the cure depth to successfully print simple propellant geometries and combustion testing to gauge the performance. Commercial-off the shelf (COTS) printers were used to print all formulations. The background of formulation development and results will be presented.
