Additive manufacturing (AM) is a manufacturing technology that is growing in both reach and capability. Areal density (kg/m^2) is aparameter of importance for space optics where mass is always a constraint and high performance always a requirement. AM shall be used in this activity to drive the areal density and the costdown, while maintaining or improving the optical performance.The activity will consist of the following tasks:- Review currently used designs for Aluminium alloy mirrors and available AM techniques. Establish product requirements for the Aluminium alloy mirror.- Design and implement an AM manufacturing process to produce a lightweight Aluminium alloy mirror.- Manufacture and optically test the mirror to verify its performance under representative mechanical and thermal environment conditions.- Deliver the mirror and the development report, with a roadmap for the application of the developed AM technology for space optics.
