Ti-6Al-4V gyroid scaffolds with high porosities in the range of 82–85% and three different unit cell sizes 2, 2.5 and 3mm were manufactured by electron beam melting (EBM) for bone implant applications. The microstructure, mechanical properties and failure mode of the scaffolds with different sample orientations were evaluated. The as-built struts showed orthogonally orientated martensite α′ needles...
Porous biomedical implants are known for their improved osseointegration due to the ingrowth of bone tissues, combined with a lower elastic modulus to solid implants, resulting in a reduced likelihood for stress shielding and implant loosening. In this work, the control of the porosity content in capsule-free powder hot isostatic pressing (CF-HIPing) of 316L stainless steel was investigated. The proposed...
