Explore advanced sensing methodologies for powder blown laser Directed Energy Deposition (DED) additive manufacturing in this comprehensive research presentation. Delve into the challenges of process monitoring and qualification in additive manufacturing, with a focus on mass flow measurement and defect detection. Learn about a novel 4-mechanism sensing approach that combines acoustic, capacitive, inductive, and piezoelectric techniques to improve mass flow measurement accuracy and potentially measure mixed powder flow compositions. Discover the development of a magnetic computed tomography system for in-situ quantification of defects, including their layer-by-layer evolution, formation, migration, and annihilation. Gain insights from Dr. Zach Brunson, Research Engineer at Georgia Tech's Woodruff School of Mechanical Engineering, as he presents cutting-edge research aimed at enhancing process repeatability and component qualification in powder blown laser DED additive manufacturing.
