N2 - 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. The US Department of Defense (US DoD) researchers are examining areas in which 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 the 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. In this study, Commercial-Off The Shelf (COTS) printers have been used to print all formulations. The background of formulation development and results are presented.
