MULTI-FUN sets a clear focus on market-creating innovation, developing advanced materials and equipment for Additive Manufacturing of multi-material parts. These new material combinations will provide a significant performance & efficiency gain in MAM products by fully integrated multi-functionalities based on novel active materials and enable MULTI-MATERIAL design in geometrically complex 3D metal parts without size limitations by innovative, cost-effective AM technologies. The novel integrated functionalities include embedded electrical conductivity, fibre-optical sensing features or innovative heat management concepts, incl. applying nanotechnologies in at least 3 variants. Leading experts in AM process & equipment manufacturing (from SMEs, IND, RTOs and UNIV) will fully cover the physical integration of these advanced materials into metallic substrates. Significant improvements in efficiency, quality & reliability of products will result in KPI numbers beyond the request (>40%), alongside reduced environ
