| Abstract Scope |
Single track and pad laser scans on bare plates continue to be a valuable experiment for AM model validation. To this end, the AMB2022-03 benchmark explores a range of individual and overlapping melt pool behaviors using individual laser tracks and 2D arrays (pads) of laser tracks on solid metal IN718 plate. Single track laser scans were created with several combinations of laser power, scan speed, and spot diameter. Two 2.5 mm × 5 mm pad scans were created by scanning the laser in the ±X-direction and ±Y-direction. Single tracks and pads were cross-sectioned perpendicular to the laser track direction and metallographically prepared for optical microscopy. The cross-sectional melt pool dimensions (depth and width) were measured in the center of single-tracks and at multiple locations in pad scans. The measurement results will be presented and compared with anonymized challenge submission results from modelers to show the relative accuracy or trends in the models. |
