Abstract

In-situ Fabrication and Repair by means of additive manufacturing with lunar regolith is a promising solution for ensuring sustainable crewed exploration of the Moon. Digital light processing is one of the additive manufacturing procedures, which are being considered for the fabrication of precise ceramic parts and instruments from lunar regolith. In the present paper, we have studied the feasibility of using a commercial DLP 3d-printer for manufacturing precise ceramic parts of a complex shape from LHS-1 lunar regolith simulant. Produced samples were analyzed employing gravimetrical densimetry, micro-indentation, SEM, and XRD. It was shown that using an on-shelf DLP printer and photo-curable resin with 72.4 wt.% of regolith simulant in-fill, complex 3d-objects can be printed and sintered to the relative density of 96%. It was found that the mineral composition of lunar regolith is the critical factor for effective DLP-printing and sintering of ceramic parts manufactured from this material.
