Material　processing　is　based　on　the　philosophy　of　either　removing　material　or　adding　material.　Traditional　machining　technologies　gradually　remove　material　from　top　to　down.　Selective　laser　sintering　(SLS)　composes　the　powder　material　bottom　up　layer　by　layer.　A　novel　method　to　sinter　powder　by　the　investigation　of　laser　interaction　with　powder　is　developed.　This　fabrication　technology　combines　material　removing　and　adding　together　named　laser　vaporizing　sintering　(LVS)　technology.　This　technology　removes　the　material　with　laser　vaporizing　and　meanwhile　the　powder　around　laser　beam　is　molten　and　sintered　to　form　structure　by　laser.　It　shows　great　potential　advantages　to　fabricate　thin　or　micro　parts　in　the　future.
