| Abstract Scope |
Laser powder bed fusion (LPBF) additive manufacturing often faces part defects due to non-uniform temperature distribution during fabrication. To address this, the authors previously introduced SmartScan, an intelligent method utilizing modeling and optimization to generate scan sequences enhancing temperature uniformity. However, its application was limited to single layers. This work extends SmartScan to three-dimensional parts by modifying the thermal model and optimization objective. Through simulations and experimental fabrication of AISI 316L stainless steel parts, the study demonstrates that the proposed SmartScan approach substantially improves temperature uniformity, diminishes part distortion, and alleviates residual stress when compared to conventional heuristic sequences. |
