The session, organized by the ASM Emerging Technologies Awareness Committee, will be moderated by Hanchen Huang, dean of engineering at University of North Texas. Following is an informal discussion by the panelists, which provides a glimpse into the state of AI/ML and AM and a preview of their more formal panel discussion scheduled for this fall. For event details, visit imatevent.org . What are your thoughts on the upcoming panel discussion on additive manufacturing (AM)? And what are some interesting or promising applications of artificial intelligence (AI) for materials engineering or characterization? Ed Herderick: I am thinking about the value stream and different things that we’re working on at Ohio State. I’d like to break down the AM discussion into three areas: in-process monitoring/ NDE, special process qualification, and the design stage. Most of my experience is in the aerospace industry. But I think it maps well to the other major applica- tions for additive, including biomedical, implantable devices, energy, infrastruc- ture, and space. Liz Holm: I would also emphasize process qualification—the design and qualification of materials for additive. That includes both the raw materials and the build outcomes. Part of process qualification is understanding both the input and the output of the process, and both AI and machine learning (ML) can help with those areas as well. Jim Williams: I think that’s right. If we could figure out how to get data from in-process sensors and analyze them so that you could identify when the process data varies enough to PANEL OF EXPERTS Elizabeth A.
