The additive manufacturing of Ti6Al4V enables customized implant production with precise control over microstructure and mechanical properties. A key challenge in Ti6Al4V implants is stress shielding, which is alleviated by introducing porosity to match the implant's Young’s modulus to that of bone. However, this reduces compressive strength. This study investigates enhancing compressive strength and osseointegration of porous Ti6Al4V by infiltrating it with hydroxyapatite (HA). Optimized cubic-porous Ti6Al4V specimens with square pores were fabricated using Laser Powder Bed Fusion (LPBF) and infiltrated with HA via the sol-gel method. Biocompatibility was assessed through corrosion rate analysis, cell attachment studies, and electrochemical analysis (EIS and PDP). XRD confirmed the presence of HA and other biominerals formed after the immersion of the Ti6Al4V/HA samples in SBF. Compression tests and degradation analysis were conducted by immersing the samples in simulated body fluid (SBF). The Ti6Al4V/HA specimens had compressive properties within the range of bone, with a maximum compressive strength of 239.4 ± 6.7 MPa and Young’s modulus of 5.5 ± 0.1 GPa after immersion in simulated body fluid (SBF) for 7 days. The corrosion rate for the same sample was found to be 0.72 mm/year.
