Abstract

This study presents the results of an analysis carried to compare the dimensional quality of parts built at different orientations as well as identify causes of dimensional inaccuracies of Electron Beam Melting (EBM) parts built in different scenarios. The scenarios considered reflect common overhanging positions of part features built in the EBM machine. The results show that the parts built on the support structure had the optimum dimensional accuracy. Furthermore, there are close quality characteristics of the cylindrical features built in the X and Y direction, i.e., perpendicular to the build direction, due to the alternating scanning direction adopted by the EBM machine.
