Cu-10Sn　alloy　with　body-center-cubic　(BCC)　lattice　structure　was　fabricated　through　selective　laser　melting　(SLM).　The　geometry　of　SLMed　BCC　lattice　Cu-10Sn　alloy　(rod　diammeter　similar　to　300　mu　m,　length　similar　to　700　mu　m)　was　in　good　agreement　with　the　design　model.　Similar　with　the　nearly　full　density　Cu-10Sn　alloy,　columnar　also　constituted　the　majority　parts　of　the　lattice　structure　Cu-10Sn,　but　exhibited　various　morphologies　due　to　the　different　grain　growth　orientation　under　thermal　effect.　The　gowth　orientation　of　columnar　grain　in　the　rods　oriented　to　the　as-fabricated　layer　due　to　the　higher　thermal　conductivity　of　the　as-fabricated　layers.　(C)　2019　Elsevier　B.V.　All　rights　reserved.
