Description

Lattice materials built via additive manufacturing feature geometric and material defects that impact their mechanical properties and optimum design. We are developing methods to integrate them in a density-based formulation for topology optimization of additively built lattice materials, and applying them for the development of structurally optimized technology in multiple sectors.
