Abstract

The rapid development of Additive Manufacturing (AM) enables a high geometrical freedom for the production of lightweight cellular structures. Through the newly gained possibilities in individualization and complexity in the areas of design and construction, optimization and generation of the initial design becomes even more important. We discuss a mixed-integer linear program (MIP) to generate a three-dimensional construction of cellular structures for a static case of loading. Additionally, based on the optimized structures, an automated construction in a CAD system allowing a numerically simulation of nonlinear material behaviour is presented. The model is planned as a support tool for engineers.
