Abstract Scope |
In situ monitoring of Laser Powder Bed Fusion (LPBF) additive manufacturing (AM) enables the
utilization of various sensors, including acoustic, optical, and thermal to swiftly identify anomalous
process behavior. The stochastic nature of LPBF necessitates faster qualification pathways to determine
parts quality without significant time investment, thereby promoting less risky adoption of
AM. Identifying pore formation through a combination of in-situ sensors without the need for computed
tomography (CT) scanning would expediate the identification of defective parts. This presentation
highlights using a variety of sensors to capture defect and process signatures for a full build plate of
tensile bars. Discussion will cover how sensor outputs were linked to final mechanical properties and CT-determined ground truth porosity.
