Abstract
Additive Manufacture (AM) comprises a group of technologies that allow to go from a 3D model to manufactured components, creating them layer by layer until the part is complete. Among the advantages of AM, the ones that apply most to astronomical instrumentation are part complexity and consolidation, the addition of functionalities, design freedom and lightweighting capability.
The aim of this paper is to present the results of the studies carried out on the lightweight metal mirror samples with the two typologies and the most promising material of those studied within the IAC for H2020. Comparisons will be made mainly in terms of metrology, dimensional tolerances and optical surface finishes of the mirrors (roughness, SFE, etc.).
