Effect of Microstructure and Internal Defects on the Mechanical Properties of Ti6Al4V Gyroid Lattice Structures for Biomedical Implants

Selective laser melting (SLM) is a laser powder bed fusion (L-PBF) technique that can be used to print lattice structures with fine complicated features. Much effort has been made to choose a lattice design that enhances the mechanical and biological functions for biomedical implants. Triply periodic minimal surface (TPMS) lattice structures, namely gyroids, have shown a great potential to match the mechanical and biological properties of bone …
