The utilization of lunar regolith for construction on the lunar surface has become a critical challenge in the field of in-situ resource utilization. This study proposes a lunar regolith manufacturing method using a high-performance resin binder, which is characterized by high regolith content and forming strength. A combined resin material with both thermosetting and photosetting properties was developed and mixed with lunar regolith to create a regolith slurry. This slurry can be directly molded or additively extruded into green bodies with specific structures. These green bodies can self-cure under the high temperatures and ultraviolet radiation present during the lunar daytime, thereby reducing energy requirements and meeting the demands of lunar construction. The study thoroughly examines the material forming processes, investigating the effects of various additive types and contents, regolith mass ratios, and process parameters on the properties of the slurry and the formed specimens. The mechanical performance and microstructure of the formed samples were also analyzed. The lunar regolith mass ratio reached up to 90 wt.%, with the highest compressive strengths exceeding 60 MPa for cast specimens and 30 MPa for printed samples. This technology shows significant potential for contributing to in-situ lunar regolith-based construction in future lunar missions.
