| Abstract Scope |
Reproducing parts of equal quality on similar additive manufacturing (AM) machines, particularly laser powder bed fusion systems can prove to be challenging due to the numerous process variables affecting final part quality. Original equipment manufacturers (OEMs) recommend regular calibration to minimize the differences in part quality. Current efforts are going towards process qualification and standardization to ensure that parts of equal quality can be fabricated regardless of where they are fabricated. As such, this study aims to assess the reproducibility of IN718 parts fabricated on three similar EOS M290 machines from IN718 material by comparing mechanical properties including tensile and fatigue behavior, and dimensional accuracy. Results showed minor differences in strength and ductility, and subtle differences in fatigue life. These differences could relate to inconsistencies in heat treatment between fabrication sites inducing different microstructures. Dimensional accuracy was unaffected and therefore reproducible among the three machines. |
