SLS/HIP是一种混合直接激光加工方法．是用选择激光烧结（SM）与无模热等静压（HIP）相结合的方法制造具有各种复杂形状的金属部件的净成形技术．SLS／HIP的基本原理是用SLS将金属粉末加工成具有一个整体的、完全致密的阻气外壳或在部件边界原位制成一个错，内部的密度要达到或 SLS / HIP is a hybrid direct laser processing method. Is a net forming technique for manufacturing metal parts of various complicated shapes by a combination of laser sintering (SM) and dieless hot isostatic pressing (HIP). The basic principle of SLS / HIP is to use SLS to process metal powder into an integral, fully dense gas-barrier enclosure or to make a fault in situ at the boundary of the component with an internal density of
