Abstract Multi material additive manufacturing (MM-AM) is an attractive approach to combine the geometric flexibility in particular of powder bed based AM processes with functional integration. A major limitation multi-material laser fusion (MM-LPBF) approaches risk contamination. In present study, implementation a concept for multi parts demonstrated. new type device contructed, and process tested fundamentally gradually by experimental means. Aspects investigated include machine feasibility, bonding issues, dilution. Microstructural analysis reveals successful build multimaterial basic geometries out steel (316L stainless steel) both nickel-based alloy copper foil. This provides whose further research offers high potential numerous applications.
