3D打印技术在建筑领域受到越来越多的关注，因为它们可能用于直接建造建筑物和其他复杂结构，这些结构也具有相当大的尺寸，几乎具有任何形状。其中有些技术依赖于惰性材料（例如沙子）通过一种特殊的粘合液体的凝聚过程，这种能力因其在空间探索中的潜在应用而引起空间界的兴趣。事实上，它为在恶劣的空间环境中建造建筑物开辟了利用现场资源的可能性。本文介绍了一项研究的结果，旨在评估使用月球土壤（也称为风化层）在月球上建造栖息地的3D打印技术的概念。应用了一种特殊的3D打印专利技术-D形，这是现有快速成型系统中最接近实现建筑物全尺寸建造的技术，并就这种技术的工作原理评估了月球风化层和陆地风化层模拟物的物理和化学特性。还开发了一种新型的月壤模拟物，它几乎完全再现了美国生产的JSC-1A模拟物的特性。此外，在空气中和真空中进行了试验，以证明与风化层模拟物的网状反应的发生。真空试验还表明，通过适当的注入方法可以防止结合液的蒸发或冻结。月球前哨站的一般要求已经明确，栖息地的初步设计也已经制定。在此基础上，选取了一段哨所围墙，并利用D型打印机和风化层模拟物进行了实物制作。还制造了试件，并对其机械性能进行了评估。(C)2013年IAA。由爱思唯尔有限公司出版。保留所有权利。
3D-printing technologies are receiving an always increasing attention in architecture, due to their potential use for direct construction of buildings and other complex structures, also of considerable dimensions, with virtually any shape. Some of these technologies rely on an agglomeration process of inert materials, e.g. sand, through a special binding liquid and this capability is of interest for the space community for its potential application to space exploration. In fact, it opens the possibility for exploiting in-situ resources for the construction of buildings in harsh spatial environments. The paper presents the results of a study aimed at assessing the concept of 3D printing technology for building habitats on the Moon using lunar soil, also called regolith. A particular patented 3D-printing technology - D-shape - has been applied, which is, among the existing rapid prototyping systems, the closest to achieving full scale construction of buildings and the physical and chemical characteristics of lunar regolith and terrestrial regolith simulants have been assessed with respect to the working principles of such technology. A novel lunar regolith simulant has also been developed, which almost exactly reproduces the characteristics of the JSC-1A simulant produced in the US. Moreover, tests in air and in vacuum have been performed to demonstrate the occurrence of the reticulation reaction with the regolith simulant. The vacuum tests also showed that evaporation or freezing of the binding liquid can be prevented through a proper injection method. The general requirements of a Moon outpost have been specified, and a preliminary design of the habitat has been developed. Based on such design, a section of the outpost wall has been selected and manufactured at full scale using the D-shape printer and regolith simulant. Test pieces have also been manufactured and their mechanical properties have been assessed. (C) 2013 IAA. Published by Elsevier Ltd. All rights reserved.
