The technology of selective laser melting, short name SLM, is one of the most promising methods of processing metals and its alloys, but the variety of materials is still limited. To extend the area of application further investigations of new materials are necessary. With the growing request for new materials the production of multi material parts are gaining interest, as they are used more and more for light weight purposes. Because of its high thermal conductivity the element copper is of particular importance to a wide variety of applications. Within this work the general eligibility of copper for selective laser melting and a hybrid material bonding between copper and steel are investigated. After searching the literature for already existing experiments and attempts of welding-based processing of copper, a study to find the correct data sets for the fabrication of pure copper onto a steel platform is executed. At the beginning of the investigations the focus was to create a typical specimen surface, which is characteristic for the process of selective laser melting. With the most promising data, additional samples were produced for metallographic characterization of the melting quality of the pure copper and its hybrid bonding to steel. The results are discussed in detail and an outlook with respect to further potential fields is given.
