A three-dimensional model from powders of a copper-nickel alloy Cu81-Ni19 composition is obtained by selective laser smelting. The 3D model microstructure is characterized by the absence of typical crystalline structure and contains elements of a quasi-amorphous state. The finished material differs from the standard monolithic cast billet with a lower surface roughness, higher hardness values while maintaining almost the same density indices.
