Additive Manufacturing of metal parts is revolutionising the space industry thanks to the new design freedom, cost reduction and performance optimization. One of the challenges of the AM process is the insufficient surface finish, internal stresses and the presence of surface defects. It is therefore important to develop finishing technologies which are capable of producing parts in a finalcondition which are compliant to space relevant requirements. Previous activities have shown that finishing technologies can be developed successfully at sample level. An activity is now required to bring the technologies to the stage where the technologies can be adopted for complex part geometries. Materials relevant for space application shall be considered.The objectives of this activity are: Select three case studies (Propulsion, Optical, RF) and their associated requirements. Define a suitable AM end to end process able to fulfil the requirements defined. Manufacture samples and breadboards to assess the capabilities of the surface finishing scenario selected. Manufacture, treat and test the complete parts for the three case studies selected.
