GuhaHengfeng Gu is a doctoral student in the Edward P. Fitts Department of Industrial and Systems Engineering at NC State University. He received his MS in Industrial Engineering from University of Louisville in May 2014. Hengfeng’s current research focuses on two metallic powder based additive manufacturing (AM) systems, Selective Laser Melting (SLM) and Electron Beam Melting (EBM).The research is trying to investigate the influence of both chemical and physical properties of powder material on the behavior of the build processes as well as the as-built part performance.The potential research outcome will give a comprehensive understanding of how powder materials behave in AM process and provide guidance for powder certification to achieve desired as-built part properties.
