The webinar, In-Situ Monitoring and Control in PBF Process, will take place on July 29th, 2021 at 10:00am EDT.

Metals additive manufacturing (AM) has been embraced by aerospace, defense, and medical industries for production and repair of high-value components and constitutes a market size of several billion dollars. In particular, laser powder bed fusion (PBF) additive manufacturing, owing to its ability to produce complex, metal components, is the subject of significant research, development, and commercialization efforts. Many such efforts are focused on ensuring reliability, repeatability, and accelerating qualifications of PBFAM processes, often with an emphasis on process mapping, in-situ process monitoring, or post-build materials characterization.

In this webinar, accepted and emerging methods for in-situ monitoring and control in PBF process will be detailed. Sensing and control efforts will be framed within the context of holistic quality assurance, including pre-process, in-process, and post-process monitoring. Both high-fidelity (e.g., high-speed visible and infrared imaging) and low-fidelity (e.g., photodiode, acoustic) methods, applied to laboratory- and production-scale systems will be critically examined. Requirements for data acquisition systems, with a focus on data synchronization and registration will be emphasized as will the role of robust data analysis (e.g., statistical methods and machine learning).
