In-situ process monitoring and adaptive quality enhancement in laser additive manufacturing: a critical review
Lequn Chen, Guijun Bi, Xiling Yao +6
Laser Additive Manufacturing (LAM) presents unparalleled opportunities for fabricating complex, high-performance structures and components with unique material properties. Despite…
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…
An Evolutional Algorithm for Automatic 2D Layer Segmentation in Laser-aided Additive Manufacturing
N. Liu, K. Ren, W. Zhang +4
Toolpath planning is an important task in laser aided additive manufacturing (LAAM) and other direct energy deposition (DED) processes. The deposition toolpaths for complex geometr…
