This study investigates the formulation, processing, hardened state properties, and additive manufacturing of sintered 3D-printable simulated lunar regolith magnesium oxychloride (MOC) cements. Sintering of these materials up to 1200 °C leads to full decomposition of the lunar regolith based MOC cement with release of HCl and water, which could potentially be captured and reused without compromising material properties. The sintering process reduces porosity and increases compressive strength, particularly when the material is initially pre-dried. 3D print manufacturing of the simulated lunar regolith cement is demonstrated using a powder binder jetting technique, showing expected pattern reproduction suitable for the manufacturing of small-scale parts. This material and processing approach could provide opportunities for future lunar fabrication of parts using additive manufacturing and in-situ resources, reducing the need for dedicated manufacturing facilities, distant transport of materials, and minimizing water demands through partial recovery during processing.

这项研究调查了烧结，可3D打印的模拟月球长石氧化氯镁（MOC）水泥的配方，加工，硬化状态特性和增材制造。这些材料的烧结温度高达1200°C，会导致基于月牙石的MOC水泥完全分解，并释放出HCl和水，可以潜在地将其捕获和再利用而不会损害材料的性能。烧结过程降低了孔隙率并提高了抗压强度，特别是在材料最初进行预干燥时。使用粉末粘合剂喷射技术演示了模拟的月球长石水泥的3D打印制造，显示了适用于小规模零件制造的预期图案再现。
