Selective Laser Melting (SLM) was used to fabricate sample parts made of two metallic materials, 316L stainless steel and UNS C18400 copper alloy. The novel approach, by the separation of a single dispensing coating system into two compartments, is described and the resulting samples were analyzed based on the bonding of their interface. A substantial amount of Fe and Cu element diffusion was observed in the fabricated samples, suggesting good metallurgical bonding and the feasibility of dissimilar metals processing in SLM.
