Selective laser sintering (SLS) technology which is based on additive material shows great advantages for its' almost no limitation in sintering material. Beside additive fabrication traditional laser processing technologies such as laser cuttinglaser drillinglaser marking are based on removing material. In this paper laser vaporizing sintering (LVS) fabrication technology has been introduced to fabricate thin wall structure. This technology is based on both material removal by laser vaporizing and material addition by laser sintering. This is a novel technology which combines two different methods to fabricate micro part. This method can sinter several powder particles together to form microstructure. It can be used to fabricate 2.5 dimension thin wall parts and hopefully will be developed to a new material removing-adding technology to produce micro-components.
