Layered part manufacturing enables part topology to be optimized internally by structuring individual layers separately, which is especially promising for large machine parts. However, the resulting part properties as a function of the selected manufacturing parameters are largely unexplored. Therefore, this paper investigates the impacts of the slicing direction, the sheet thickness as well as the adhesive on anisotropic damping and stiffness values of adhesively bonded steel parts. A cantilever beam of symmetric cross-section is chosen as an easy-to-manufacture geometry. Three redundant specimens were prepared for each of six parameter variations investigated within this study, resulting in a total of 18 investigated beams. The results indicate highly anisotropic stiffness and damping as a function of the layer build-up direction and it was found that the modal damping rises with increasing amount of adhesive. These findings must be taken into account for future applications of layered lightweight machine parts and their simulative predictability should be studied.
