Abstract in another language

Topology optimization allows the identification of an optimal material distribution within a defined design domain under given boundary conditions. It is therefore extremely suitable for realizing lightweight construction potentials and structurally optimized components. However, the resulting design proposals are often difficult to interpret and, due to their structure, can rarely be produced using conventional forming processes. This paper shows how finite spheres can be used to consider manufacturing restrictions in topology optimization, so that the necessary support structure of the optimized parts obtained is minimized in additive manufacturing. To further minimize the material usage in manufacturing, an approach for automated component orientation and support structure generation is presented.
