In the final thesis, the topological optimization of a 3D printed cantilever wall bracket for a bicycle is presented. First, the theoretical foundation is provided, with an emphasis on optimization methods and the use of 3D printers. The preparation of the geometry, selection of constraints and optimization objectives, and determination of appropriate parameters— such as the degree of accuracy, minimum element size, and number of iterations—are
described. Subsequently, the optimization results are shown, along with a comparison of the bracket's behavior using different materials, where PETG and PC were employed. This is followed by the adaptation of the optimized geometry to the requirements of 3D printing, where key process parameters were defined, such as layer height, infill density and pattern, number of perimeters, and support structures. Based on these settings, a prototype was manufactured, which was printed and then experimentally tested. The testing involved mechanical loading with a 24 kg mass and mounting the bicycle on the bracket. The results demonstrated that it is possible to produce a functional bracket through the combination of topological optimization and additive manufacturing, which meets practical requirements
and confirms the validity of the applied approach.
