Laser metal deposition (LMD) is an additive manufacturing process. Unlike conventional manufacturing process which is subtractive, LMD produces part layer by layer from the ground up and has been used to fabricate fully dense components using a variety of metallic powders. This paper investigates the evolving properties of laser deposited 17-4PH stainless steel. The microstructure was martensitic with a dendritic structure. The average microhardness of the samples was found to be less than their wrought counterpart.
