The study investigates the optimization of build orientation in additive manufacturing, an influential factor affecting mechanical properties, surface and part quality, and process efficiency. Two orientation evaluation strategies are compared: the commercial software Autodesk Netfabb and a novel multi-criteria algorithm developed at RWTH Aachen University. The proposed algorithm is designed to minimize thermally induced deformation during printing with Powder Bed Fusion – Laser Beam Melting technology. It employs six Key Performance Indicators (KPIs) derived from part geometry, which are evaluated on a layer-by-layer basis to assess deformation risk. While the study identifies correlations between geometric KPIs, the orientation ratings generated by the algorithm exhibit inconsistencies and limited reliability.
