TPMS Lattice Structure derived using Topology Optimization for the Design of Additive Manufactured Components

Abstract

The integration of lattice design approaches and topology optimization is the next step in realizing optimal lattice designs for Additive Manufacturing (AM). Hence, this study focuses on a topological optimization method that allows to derive lattice structures from topological optimization results suitable for additive manufacturing such that TPMS lattices are designed to replace solid volumes. To find these lattice solutions, we used the intersected lattice. Simulation tests was carried out to verify the superior stiffness properties of the optimized intersected lattice compared to the basic design using a solid topology optimization solution.
