Technology of Quality Detection and Feedback in Laser Powder Bed Fusion Process
摘要
As the laser powder bed fusion (LPBF) processing process involves more than 130 processing parameters, the processing process and manufacturing quality have strong instability and relatively poor repeatability. The research on the quality detection and feedback technology for the LPBF process is the key content to explore the manufacturing and defect mechanism, as well as the inevitable stage to realize the quality control and backtracking of the LPBF process and improve the LPBFed part quality and level.
