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 seminar, we will discuss the feasibility of using a commercial DLP 3d-printer for manufacturing precise ceramic parts of a complex shape from LHS-1 lunar regolith simulant. It will be shown that using an on-shelf DLP printer and photo-curable resin with 72 wt.% of regolith simulant in-fill, complex 3d-objects can be printed and sintered to the relative density of 96%. It will be also shown how mineral composition of lunar regolith influence on its printability by means of stereolithogarphy and its sintering behavior.

Maxim Isachenkov is a 3-rd year PhD student at CMT center of Skolkovo Institute of Science and Technology in Moscow, Russia. His PhD thesis topic is 3D-printing with lunar regolith by means of laser stereolithography. He was always keenly interested in two things – chemistry and space exploration. After graduating with the specialist degree (B.A. +M.Sc.) from D.I. Mendeleev University of Chemical Technology of Russia, he found a way to combine his interest in space exploration and knowledge in material science in his PhD research. With the world on the verge of a new Moon Race, he decided to apply his expertise in ceramics and material science to start the research on additive manufacturing of functional ceramic parts from lunar regolith at Skoltech, under the supervision of professor Igor Shishkovsky.
