Laser melting experiments were carried out with the MOONRISE payload, installed on the mobile manipulator, MIRA3D. The MOONRISE payload was developed to demonstrate the feasibility of additive processing of lunar regolith with the help of lasers on the Moon within a lunar surface mission in the next years. The development of hardware for the flight to the moon is well advanced and, if successful, would pave the way for the use of laser melting for production of components from regolith. The aim of the experiments described in this article was to test the planned scenario on the Moon, especially the interaction between laser payload, manipulator, and soil surface, and to identify suitable process parameters for production of two-dimensional (2D) objects. The ability to produce 2D objects is an important intermediate step on the way to produce large three-dimensional structures such as habitats, walls, or foundations. During the experiments, specimens with a size of ∼20 × 20 × 4 mm were repeatedly produced. As analog material, two synthetic lunar soils produced with the modular regolith simulant systems from Technische Universität Braunschweig (TUBS) were used. The experiments were conducted under Earth gravity and atmospheric conditions. This article describes the hardware used, procedure for carrying out the experiments, and properties of the produced samples.

使用移动机械手上的 MOONRISE 有效载荷对月球风化层模拟物进行二维激光熔化

使用安装在移动机械手 MIRA3D 上的 MOONRISE 有效载荷进行了激光熔化实验。开发 MOONRISE 有效载荷是为了证明在未来几年的月球表面任务中借助月球激光对月球风化层进行增材加工的可行性。飞往月球的硬件开发进展顺利,如果成功,将为使用激光熔化从风化层生产组件铺平道路。本文所述实验的目的是测试月球上的计划场景,尤其是激光有效载荷、机械手和土壤表面之间的相互作用,并确定用于生产二维 (2D) 物体的合适工艺参数。生成二维对象的能力是生成大型三维结构(例如栖息地、墙壁或地基)的重要中间步骤。在实验过程中,反复制作了尺寸约为 20 × 20 × 4 mm 的样品。作为模拟材料,使用了由布伦瑞克工业大学 (TUBS) 的模块化风化层模拟系统生产的两种合成月球土壤。实验是在地球重力和大气条件下进行的。本文介绍了所使用的硬件、进行实验的过程以及所生产样品的特性。使用了布伦瑞克工业大学 (TUBS) 的模块化风化层模拟系统生产的两种合成月球土壤。实验是在地球重力和大气条件下进行的。本文介绍了所使用的硬件、进行实验的过程以及所生产样品的特性。使用了布伦瑞克工业大学 (TUBS) 的模块化风化层模拟系统生产的两种合成月球土壤。实验是在地球重力和大气条件下进行的。本文介绍了所使用的硬件、进行实验的过程以及所生产样品的特性。
