With the demand for an increasing diversification of the product spectrum along with the decreasing unit quantities of each production lot, the upcoming innovative production concepts of a flexible and digitized production ("fourth industrial revolution") tend to substitute more and more the traditional product development and production processes, which are already reaching their limits or fail to address these trends. At the same time, new technologies like additive manufacturing basically create new opportunities regarding extensive potentials in product development and manufacturing, but mostly with just insufficient strength regarding structural components. Therefore, this contribution presents an innovative technological and procedural conception of a hybrid additive manufacturing process - fiber-reinforced sandwich structures based on selective laser sintering technology. In this way, the concept supports the design of complex lightweight components, in particular through the application of a "hybrid additive lightweight engineering" (HALE) methodology.
