In this, additive manufacturing, particularly in the implementation of requirements with respect to light-weight construction and sustainability, offers several advantages compared to conventional manufacturing methods. Therefore, this article will primarily introduce and compare current concepts for sustainable design using additive manufacturing. These will, above all, consist of the production of complete fuselages and wings by means of rapid prototyping or also rapid tooling. In addition, a new concept will be introduced in which a UAV using AM can be implemented through the combination of very light components and a preferably resource-saving manufacturing method. In this process, a three-dimensional spaceframe is used in combination with a covering in the construction of the wing. Hereby, the development process for sustainable design using additive manufacturing will be analyzed and the results will be explained by means of concrete case studies. In conclusion, the results of these case studies will be compared to the latest technology regarding wing span load.…
