【Abstract】 The thin-walled 316L stainless steel parts was prepare d by laser rapid prototyping. The results showed that the shaped parts with com pact microstructure is characterized by the dendrite and the uniformly distribu ted chemical composition. And the mechanical properties of the thin-wa lled metal parts by laser rapid prototyping were comparable to those of the conventionally machined metal parts.更多还原
