Abstract: The development of additive manufacturing (AM) has been driven primarily by high-tech industries, e.g. medical or aerospace. However, for industrial goods or consumer products made of metallic materials, a breakthrough is still prevented. One approach to reducing manufacturing costs and time is the combination of additive and conventional manufacturing (hybrid production). Conventional semi-finished products are functionalized by means of additive processes in component areas with high requirements (e. g. thermal conductivity, wear resistance). For this purpose, the combination of powder bed-based AM processes such as laser powder bed fusion (L-PBF) or electron powder bed fusion (E-PBF) and conventional processes was investigated. The analysis of the advantages and risks is based on additive-conventional demonstrators. In this paper, the limits of the individual processes and approaches for combination of these are presented. Furthermore, implemented solutions are discussed with regard to their component properties, the possible material spectrum and economic efficiency.
