Topology optimization of components using an implicit geometric model representation

This paper explores methods for topological optimization of structures and the particularities of their implementation. It describes lattice and other complex geometric structures with regularly repeating unit cells that provide non-solid internal filling of components, taking into account the feasibility of their fabrication using additive manufacturing technologies. A case study of topological optimization using an implicit geometric model representation was conducted for a component intended for production via selective laser melting of metal powder alloys. The optimization resulted in a 27% reduction in the component’s mass without compromising its mechanical strength, achieved through modification of the internal geometry. The study emphasizes the importance of verifying the results of topological optimization under operational loads while accounting for the specific characteristics of additive manufacturing technologies.
