| Abstract Scope |
Within lightweight applications, powder bed fusion of metals using a laser beam (PBF-LB/M) allows the realization of filigree structures at minimal use of material. A traditional element of lightweight construction are sandwich sheets. These lightweight elements contain both geometrically simple (cover sheets) and geometrically complex (core structure) elements. Conventional Manufacturing of core structures is limited in terms of complexity. Additive Manufacturing of sheets has disadvantages in terms of economic efficiency. A combination of additive and conventional manufacturing processes is proposed to eliminate both disadvantages. Therefore, this publication presents a fabrication route to produce hybrid sandwich sheets. The hybrid sandwich sheets are manufactured using a rolled cover sheet (<1 mm) as base plate and additive manufactured core structures including an upper cover sheet. A developed mounting system for implementation in the PBF-LB/M process is presented and evaluated concerning manufacturing criteria such as process stability and dimensional accuracy of the built-up components. |
