Abstract

In-Space Manufacturing (ISM) needs material-efficient processes or the usage of locally available resources. This article presents two successfully applied approaches: Laser Powder Directed Energy Deposition (LP-DED) realized in microgravity on Earth for the first time using Ti-6Al-4V and substrate-free single layer powder bed fusion (PBF) under lunar gravity using LX-I50 regolith simulant. The Einstein-Elevator, a third-generation drop tower, is used to simulate the environmental conditions of space regarding gravity. The research results confirm the feasibility and open up new perspectives for space research, particularly concerning resource-efficient manufacturing technologies in future missions.

微月重力条件下激光粉末定向能沉积和无基体单层粉末床熔合

空间制造（ISM）需要材料效率高的工艺或本地可用资源的使用。本文介绍了两种成功应用的方法：利用Ti-6Al-4V首次在地球微重力条件下实现激光粉末定向能沉积（LP-DED）和利用LX-I50模拟表土在月球重力条件下实现无基体单层粉末床熔融（PBF）。“爱因斯坦电梯”是第三代落差塔，用于模拟太空重力环境条件。研究结果证实了可行性，并为空间研究开辟了新的前景，特别是关于未来任务中的资源高效制造技术。
