Master thesis in the field of
„Mechanical Testing and Characterization of 3D-printed Metamaterials”

Metamaterials offer unique mechanical properties, e.g. negative Poisson’s Ratio, variable stiffness, foldability, etc. The properties are usually defined by geometric parameters of the structure. Con-ventional processing techniques limit the possible geometries that can be manufactured. With addi-tive manufacturing, or 3D-printing, new metamaterials can be designed and fabricated. The goal of the thesis is to examine the influence of mechanical properties on a newly designed functional metamaterial, manufactured with selective laser sintering (SLS). For this, numerical simulations in combination with mechanical testing of this metamaterial will be conducted. To generate material models for the simulation, different material tests on specimen level (bending-, tensile and impact-tests) will be made at different temperatures (-30 °C to 23 °C). The metamaterial itself is character-ized with compression tests, aided with optical measurements. The results are then compared to those from numerical simulations. Depending on the candidate’s preferences the mechanical as-pect (numerical simulation and testing) or the processing aspect (FFF or DLP printing of additional metamaterial geometries) are focused in the thesis.
