Building Orientation and Post Processing of Ti6Al4V Produced by Laser Powder Bed Fusion Process

Laser powder bed fusion, particularly the selective laser melting (SLM), is an additive manufacturing (AM) technology used to produce near-net-shaped engineering components for biomedical applications, especially in orthopaedics. Ti6Al4V commonly producing orthopaedic implants using SLM because it has excellent mechanical qualities, a high level of biocompatibility, and corrosion resistance. However, main problems associated with this process are result its surface properties: be able promote cell attachment but, at same time, avoid bacteria colonization. Surface modification as post-processing technique provide items unique qualities that can improve their functionality performance particular working conditions. The goal work was analyse samples fabricated by different building directions relation plate (0° 45°) post-processed anodization passivation. results demonstrate how production post processes had impact on osteoblast attachment, mineralization, osseointegration over extended period time. Though treatment cytotoxic, biocompatibility as-built specimens after passivation confirmed. In addition, discovered effective increases mineralization these types 3D-printed surfaces.
