Abstract：

Rapid　Prototyping　(RP)　technology　develops　fast　recent　year.　It　is　an　inevitable　trend　to　adopt　laser　melting　metal　powder　material　directly　to　make　metal　part　from　RP　technology　to　RM　(Rapid　Manufacturing).　However　at　present　it　is　still　at　the　stage　of　exploring　to　utilize　micro　powder　metal　material　for　micro-fabrication.　In　this　paper　two　methods　of　microfabrication　were　investigated.　One　is　selective　laser　micro　sintering.　Equipment　of　YAG　doubling　frequency　laser　was　used　to　sinter　metallic　powder　materials　to　fabricate　micro　part.　Another　is　microcladding　fabrication.　With　special　designation　of　powder　feeder　the　fused　deposition　of　metallic　powder　was　conducted.　The　impact　factors　such　as　laser　parameters,　processing　parameters　on　micro　fabrication　were　analyzed.　Through　optimization　in　the　parameters,　a　micro　metal　part　has　been　successfully　fabricated.
