| Abstract Scope |
Directed energy deposition (DED) additive manufacturing possesses the unique ability to create complex, large-scale, and multi-material structures. Complex thermofluidic behavior and process anomalies have limited the DED application scope to coatings and low aspect ratio geometries. Recent advances in machine learning and embedded sensing have enabled new understandings of DED process physics, yet there remains a significant gap between anomaly detection and automated correction. This work presents an open-architecture wire-laser DED testbed built to address this gap. The testbed enables real-time feedback of critical systems including the incident laser power, the wire feed velocity, and robot trajectory. This work will highlight recent efforts at fusing heterogeneous in-situ data stemming from acoustic, vision, and wire feed sensors. A dynamic robotic path planning strategy via a digital twin will also be presented. By bridging the detection-correction gap, this work addresses critical DED limitations and strengthens applications and capabilities for DED technologies. |
