Abstract
In the Laser Powder Bed Fusion (LPBF) additive manufacturing (AM) process, a high-speed scanning laser beam is employed to construct components by melting and fusing metal powder together. While AM is generally characterized as a layer-by-layer technique, LPBF actually builds parts on a voxel-by-voxel basis, utilizing a point laser heating source. As a result, managing the LPBF process at the voxel level – that is, focusing on individual 3D printing elements or volume pixels – will be highly beneficial. In this study, we will explore the laser control requirements necessary for achieving voxel-level precision in the LPBF process and demonstrate these concepts through experiments.Conference Dates
