By reducing the weight of the aircraft, fuel consumption and the associated emissions can be reduced. For aircraft cabin interiors so-called sandwich structures are established. A major issue with these sandwich constructions is the load introduction, often causing over dimensioning, which counteracts the desired lightweight goals. Additive manufacturing offers new possibilities for structural design and customisation due to its design freedom. By using the Direct Energy Deposition process, which only requires a local inert gas atmosphere, components with large dimensions are feasible. However, this manufacturing process results in great challenges regarding accuracy, manufacturability, e.g. the use of closed cross-sectional profiles and the positioning of the build platform. In this paper a process to tackle these issues is developed. Applying the developed process, a design of a cabin partition is developed. From this design, bending specimens are derived, manufactured and tested to evaluate the feasibility and validate simulation models. It emerges that circular cross-sections in particular should be preferred for the next cabin partition design.enTechnology::620: EngineeringConference Paper10.1007/978-3-662-69327-8_3Conference Paper
