Multimodal sensor fusion for real-time location-dependent defect detection in laser-directed energy deposition
Lequn Chen, Xiling Yao, Wenhe Feng +2
Real-time defect detection is crucial in laser-directed energy deposition (L-DED) additive manufacturing (AM). Traditional in-situ monitoring approach utilizes a single sensor (i.e…

Multisensor fusion-based digital twin in additive manufacturing for in-situ quality monitoring and defect correction
Lequn Chen, Xiling Yao, Kui Liu +2
Early detection and correction of defects are critical in additive manufacturing (AM) to avoid build failures. In this paper, we present a multisensor fusion-based digital twin for…
