Surface Topography and Biocompatibility of cp–Ti Grade2 Fabricated by Laser‐Based Powder Bed Fusion: Influence of Printing Orientation and Surface Treatments

The selective laser melting process, commonly known as laser-based powder bed fusion (LB-PBF), enables the production of structures with unprecedented degrees freedom that represents an excellent condition for development metallic implants biomedical applications. Herein, effects energy density on relative and microstructure (presence internal defects) cp-TiGd2 fabricated by LB-PBF are studied. Additionally, influence printing orientation different surface treatments topography biocompatibility investigated. aim research is to develop additive manufacturing process parameters can achieve full satisfactory biocompatibility, a low-cost alternative materials such Ti–6Al–4 V Ti–6Al–7Nb. A wide range variation leads optimized high up 99.97 ± 0.008%, improved roughness, noncytotoxicity in horizontal inclined as-built condition, well Al2O3 (blasting angle 0°) condition.
