... Abstract The overhang down-skin surface exhibits distinct behaviors compared to the regular up-skin surface in the powder bed fusion process. Evidence suggests that weak support could be the primary cause of these differences. Previous studies by the authors have indicated that the unique...

... Abstract Despite the growing prevalence and use of custom metal-based parts produced by powder bed fusion (PBF) processes, overheating remains an issue that prevents stability and zero-defect parts from being printed. Data-driven methods utilizing existing data of prior prints are often...

... enhancements. Compared to other manufacturing techniques, such as laser powder bed fusion (L-PBF), FSP produces parts characterized by improved grain refinement and reduced occurrence of defects, such as pores and hot cracks. A characteristic feature of FSP is that the velocity field introduced...

... overall, process-monitoring performance. The work is based on a recent, laser powder bed fusion (LPBF) experiment that was conducted to create overhang surfaces throughout a 3D part. The data from that experiment is used to illustrate and validate the proposed method. The overhang features were designed...
