Sintering Regolith with Solar Light

This Horizon 2020 project, enhances the additive layer manufacturing (ALM) technique of solar sintering lunar regolith advancing the Technology Readiness Level from TRL3 (demonstrating the ability to sinter regolith in a laboratory set-up, with a moving table, in a solar furnace), to a TRL5 (demonstrating a movable printing head with accurate pointing of a concentrated solar beam, and incremental deployment of regolith on the printing surface). In addition, a near TRL6 is achieved demonstrating solar sintering in a vacuum chamber. Based on the Finite Element Model produced in the project and the mechanical properties of solar sintered regolith, architectural scenarios and applications are developed.
