Ti6Al4V is widely utilized in orthopedic implants due to its excellent mechanical properties, corrosion resistance, and biocompatibility. However, traditional solid titanium exhibit an elastic modulus (90–115 GPa) significantly higher than that of human bone (10–30 GPa), leading stress shielding implant loosening. To address this, porous alloys have been developed better match elasticity. Additive manufacturing, particularly selective laser melting (SLM), enables precise control over pore size porosity, thereby tuning properties. Nevertheless, SLM-produced structures often suffer from powder adhesion, which compromises integration patient safety. In this study, bulk samples were fabricated via SLM with a fixed power 200 W varying scanning speeds (800–1400 mm/s). Density measurements surface defect analysis identified 1200 mm/s as the optimal speed. Cubic unit cell scaffolds different diameters (400, 600, 800 μm) porosities (60%, 80%) subsequently designed. Compression tests revealed 400 μm diameter 60% porosity exhibited highest compressive strength (794 MPa) fracture strain (41.35%). Chemical polishing using diluted HF-HNO3 solution (1:2:97) effectively removed adhered without significant structural degradation, 40 min duration.
