The objective of the project was to develop a deployment and pointing mechanism as a core component for antenna pointing in future spacecraft for institutional and commercial applications. The main technological objectives for the development of this deployment and pointing mechanism were the optimization and design iteration by building and testing a breadboard mechanism model as well as the production of a mechanism demonstrator by means of additive manufacturing processes. The project included the consolidation of the technical requirements and the identification of the main requirements as a basis for the development of the breadboard mechanism model and the additive manufacturing demonstrator. The relevant requirements were verified by building and testing the models. A development status corresponding to TRL5 was achieved for the breadboard mechanism model. For the additive manufacturing demonstrator, a development status between TRL3 and TRL4 was achieved. As part of the work on the additive manufacturing demonstrator, extensive investigations were also carried out on material behavior in relation to additive manufacturing regarding manufacturing processes, materials, material properties, post-treatment processes and tests for characterization and verification. Test conduction and results of the test campaigns will be presented with focus on functional and environmental tests as well as lessons learned.
