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