Abstract Scope |
Powder bed fusion (PBF) additive manufacturing attracts attention in various industries, but its potential is limited by the defects due to non-uniform temperature distribution. To address this problem, the authors have recently presented SmartScan, an intelligent approach that is model-based and optimization-driven for generating scan sequences. The experiments demonstrated that the approach could improve up to 41% in thermal uniformity and 47% in deformation reduction compared to the existing method. However, the current version of SmartScan has only been applied to laser scanning of simple geometric patterns with uniform-length features. This work extends SmartScan to complex geometries by reformulating the original method. Simulations involving laser marking of AISI 316L stainless steel plates demonstrate that, compared to heuristic sequences, the proposed SmartScan approach improves temperature uniformity by up to 7.24 times with high efficiency. The experiment was planned for the final poster, which contains deformation reduction results. |
