Lightweight　lattice　structures　have　great　potentials　for　the　application　in　medical　industries　due　to　their　large　specific　surface　area　and　high　strength-to-weight　ratio.　Selective　laser　melting　(SLM)　as　one　of　the　most　attractive　additive　manufacturing　processes　has　been　widely　used　for　the　fabrication　of　porous　structures.　In　this　study,　two　Ti6Al4V　lattice　structures,　trabecular　(Trab.)　and　triply　periodic　minimal　surface　(TPMS),　were　produced　through　SLM　to　study　the　microstructural　distribution　and　compressive　properties　with　different　cell　types.　The　results　show　that　cell　type　has　insignificant　effect　on　the　microstructure　of　the　SLM　lattice　structures　studied　in　this　work.　For　both　lattice　samples,　refined　near-equiaxed　beta　phase　was　formed　in　the　lattice　struts,　while　coarse　beta　phase　was　formed　in　the　solid　bulk　region.　However,　cell　type　posed　significant　effects　on　the　compressive　properties　of　the　lattice　structures.　The　Trab.　structure　was　found　to　have　higher　compressive　strength　and　better　energy　absorption　capacity　than　the　TPMS　structure.　This　work　demonstrated　that　the　elastic　modulus　of　Trab.　(5.58　GPa)　and　TPMS　(5.51　GPa)　lattices　could　be　comparable　to　that　of　natural　bones　(0.022-21　GPa)　through　rational　structural　parameters　design,　which　can　avoid　the　stress　shielding　effect　that　always　occurs　on　biomedical　implant.
