abstract = "With substantial progress in additive manufacturing (AM) technology in the recent years, AM parts are on the verge of becoming an economical option for small series manufacturing and on-demand spare parts. Especially Fused-Filament-Fabrication (FFF) has found widespread use in industrial
as well as in private applications, due to its many advantages. Depending on the application, the elastic and dynamic behavior of a structure is critical, e.g. when designing resonating elements in meta materials. To predict the dynamic behavior of a structure, the most important parameters
are the storage modulus, loss modulus and the density of the material. In polymers the first two parameters are typically frequency-dependent, and in the case of FFF parts they are also strongly anisotropic, due to the layer- and path-wise fabrication process. In this study, samples of FFF
3D-printed ABS parts with different printing parameters are investigated. Dynamic mechanical analyses are performed to obtain the temperature- and frequency-dependent properties of each parameter in the frequency range of 20 Hz to 20 kHz. The results show that the frequency-dependency is constant
over a variety of parameter sets. Subsequently, a bigger number of samples are measured in quasi-static load to obtain the variance within each parameter set.",
