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…

In-situ crack and keyhole pore detection in laser directed energy deposition through acoustic signal and deep learning
Lequn Chen, Xiling Yao, Chaolin Tan +6
Cracks and keyhole pores are detrimental defects in alloys produced by laser directed energy deposition (LDED). Laser-material interaction sound may hold information about underlyi…
