Rapid　prototyping　(RP)　technology　has　developed　fast　in　the　last　year.　It　is　an　inevitable　trend　to　adopt　laser　melting　metal　powder　material　directly　to　make　metal　parts　from　RP　technology　to　rapid　manufacturing.　However,　at　present　it　is　still　at　the　stage　of　explorlation　to　utilize　micro　powder　metal　material　for　microfabrication.　In　this　article　two　methods　of　microfabrication　were　investigated.　One　is　selective　laser　microsintering.　Equipment　of　YAG　doubling　frequency　laser　was　used　to　sinter　metallis　powder　materials　to　fabricate　the　micro　part.　Another　is　microladding　fabrication.　With　special　designation　of　a　powder　feeder　the　fused　deposition　of　metallic　powder　was　conducted.　The　impact　factors　such　as　laser　parameters,　processing　parameters　on　microfabrication,　were　analyzed.　Through　optimization　in　the　parameters,　a　micrometal　part　has　been　successfully　fabricated.　(C)　2004　Laser　Institute　of　America.
