Metallic additive manufacturing at the Army Research Laboratory
Abstract: An overview of the Army Research Laboratory’s (ARL) Center for Advanced Manufacturing Science is provided, showcasing the actively expanding research activities in additive manufacturing (AM) of metallic components. ARL is pursuing an integrated approach to metallic AM linking materials, manufacturing, and design development concurrently. This framework seeks to link next-generation alloy development for optimized feedstocks, AM process modeling development, and advanced topology optimization (TO) algorithm development to design for AM through incorporation of manufacturing capabilities and constraints into the design process. Disruptive improvements in metallic AM which meet property requirements for in-service use necessitate the development and integration of advanced modeling and simulation tools in the manufacturing approach in order to understand the fundamental manufacturing science related to processing parameters, including their effect on the resulting microstructures and the properties of AM parts.
Bio: Dr. Brandon McWilliams is the lead for metallic additive manufacturing at the Army Research Laboratory. Brandon earned his PhD in Materials Science and Engineering from Drexel University in 2008. His research interests include multi-scale modeling and experimental validation at relevant length and time scales, constitutive modeling, process modeling for virtual manufacturing, electric field assisted sintering phenomena, and additive manufacturing.
