Innovative materials have been developed to imitate the strong and lightweight properties found in natural systems, such as bones and sponges. These materials have a porous microstructure alternating between solid and void. Innovative manufacturing techniques, like 3D printing, have facilitated the production of cellular materials, including healthcare devices. However, 3D printing can be time-consuming depending on material, infill pattern, and printing parameters. This study presents a computational tool integrating numerical homogenization and topological optimization to investigate the mechanical properties of different infill patterns on 3D printed devices. The aim is to minimize material use and printing time while retaining acceptable structural response, improving the production of orthopaedic devices using 3D printing.
