| Abstract: | The rectangle thin wall tube of 316 stainless steel and the contortion thin wall tube of 663 copper alloy are fabricated by Laser Rapid Prototyping. The fabricated metal parts are identical with blue print. The as-formed metal parts are fully dense, homogenous and free of defects. Chemical composition analysis show that the chemical composition distribution of metal parts is uniform and the chemical composition of metal parts is same as that of metal powder. The mechamical properties of the metal parts by Laser Rapid Prototyping are equal to that of the materials by conventionally processed method. |
