Mankind is setting to colonize space, for which the manufacturing of habitats, tools, spare parts and other infrastructure is required. Commercial manufacturing processes are already well engineered under standard conditions on Earth, which means under Earth’s gravity and atmosphere. Based on the literature review, additive manufacturing under lunar and other space gravitational conditions have only been researched to a very limited extent. Especially, additive manufacturing offers many advantages, as it can produce complex structures while saving resources. The materials used do not have to be taken along on the mission, they can even be mined and processed on-site. The Einstein-Elevator offers a unique test environment for experiments under different gravitational conditions. Laser experiments on selectively melting regolith simulant are successfully conducted under lunar gravity and microgravity. The created samples are characterized in terms of their geometry, mass and porosity. These experiments are the first additive manufacturing tests under lunar gravity worldwide.

人类将开始殖民太空，为此需要制造栖息地，工具，零件和其他基础设施。商业生产过程已经在地球上的标准条件下进行了精心设计，这意味着在地球的重力和大气条件下。根据文献综述，在月球和其他空间引力条件下的增材制造仅得到了非常有限的研究。特别是，增材制造具有许多优势，因为它可以生产复杂的结构，同时节省资源。使用的材料不必随团携带，甚至可以在现场进行开采和加工。爱因斯坦电梯为不同引力条件下的实验提供了独特的测试环境。在月球重力和微重力作用下，成功地进行了选择性熔化雷格石模拟物的激光实验。所创建的样品的特征在于其几何形状，质量和孔隙率。这些实验是全球首例在月球重力作用下进行的增材制造测试。
