Matrix transformation of lunar regolith and its use as a feedstock for additive manufacturing.

Building a sustainable human habitat on the Moon requires advances in excavation, paving, and additive manufacturing to construct landing pads, surface transportation arteries, resilient shelters, and scientific outposts. Construction of infrastructure elements on the lunar surface necessitates exploration of the interfacial reactivity of locally sourced regolith and the adaptation of Earth-based construction techniques. Various crosslinking frameworks and sintering methods have been proposed as a means of consolidating lunar regolith into load-bearing structures but each have challenges related to incomplete understanding of reaction chemistry, excessive thermal budgets, and lack of universal applicability to different mineral components of regolith.
