The influence of selective laser melting defects on the fatigue properties of Ti6Al4V porosity graded gyroids for bone implants

Porosity grading of metallic lattice structures is becoming a favorable design for bone implant applications since these structures mimic the bone mechanical and biological properties. Especially when using bio-mimetic unit cell designs created by triply periodic minimal surfaces (TPMS), such as gyroids, making these types of lattice structures dominant over other CAD-based designs. In this study, the manufacturability of gyroids is tested by...
