| Abstract Scope |
Powder Bed Fusion (PBF) enables the production of integrally-designed, stiff and lightweight structures, which are prone to vibration due to their low structural damping capabilities. Several studies have demonstrated the effectiveness of particle damping in such components or specific specimens to counteract this disadvantage by leaving unfused powder inside of the components during manufacturing. However, there is a lack of large-scale studies evaluating the reproducibility of these particle dampers, particularly in relation to expectable variances in industrial additive manufacturing (AM) processes. This presentation demonstrates how the damping of specimens with thin and flat cavities varies depending on adjustable parameters in the design and build job preparation, as well as the expected scatter of the damping properties independent of these parameters. In particular, different states of powder sintering in the cavities depending on the machine-powder combination exemplifies the sensitivity of the damping effectiveness of these additively manufactured particle dampers. |
