在月球上建立地外基地是未来太空探索的迫切需求，具有重要的实用性和科学意义，促使航天科学家提出了许多可行的制造方法。在此，我们通过数字光处理（DLP）技术制造了月球风化层模拟物的建筑和功能结构，然后进行烧结。将CLRS-2月壤模拟粉与光固化树脂混合制成印刷浆料，该浆料具有良好的印刷性能。分析了模拟物的微观结构、化学成分、粒度分布和热重特性。烧结样品的平均抗压强度和抗折强度分别为428.1MPa和129.5MPa，高于以往的研究结果。这些改善的机械性能可能是由于小的平均孔径和化学组成。
It is highly desirable to establish an extraterrestrial base on the moon due to its practicality and scientific significance in the future space explorations, which promotes aerospace scientists to propose many conceivable fabrication methods. Herein, we fabricated architectural and functional structures with lunar regolith simulants via digital light processing (DLP) technology, followed by sintering. The printing slurry was prepared by mixing CLRS-2 lunar regolith simulant powders with photocurable resins, and it exhibits excellent print-ability. The microstructures, chemical compositions, particle size distribution and thermal-gravimetric characteristic of the simulants were analyzed, respectively. The average compressive strength and flexure strength of the sintered samples are 428.1 MPa and 129.5 MPa respectively, which are higher than those reported in previous researches. These improved mechanical properties could be due to the small average diameter of pores and the chemical compositions.
