America Makes proudly announces the second of two Directed Project Opportunities made available currently to its members, funded by the Air Force Research Laboratory (AFRL), Materials and Manufacturing Directorate, Manufacturing and Industrial Base Technology Division. The second Directed Project Opportunity focuses on advancing additive manufacturing (AM) post-processing techniques (AAPT) with the objective of gaining a better understanding of the available techniques in order to achieve qualified parts and certified processes, as well as reduce costs.
The focus of the AAPT Directed Project is of particular interest to AFRL as it seeks to further expand the use of Selective Laser Melting (SLM) for critical parts.
Through the AAPT Directed Project, AFRL specifically seeks to address two main issues. First, quantify the mechanical performance debit of using as built SLM surfaces to fabricate high-temperature nickel super alloy canonical features, such as thin walls and narrow flow channels. Second, quantify the effectiveness of Hot Isostatic Pressing (HIP) when producing high-temperature nickel super alloy canonical features, such as thin walls and narrow flow channels.
