Characterization of laser direct deposited metallic parts

Laser direct deposition of metallic parts is a new manufacturing technology, which combines with computer aided design, laser cladding and rapid prototyping. Fully dense metallic parts can be directly obtained through melting coaxially fed powders with a laser. The microstructure and properties observation of laser direct deposited 663 copper alloy and 316L stainless steel samples indicate that, the formed parts are fine, homogenous and free of defects, the as-deposited mechanical properties are equal to or exceed those for casting and wrought annealed materials.
