Zusammenfassung:
The applications of the additive manufacturing process Laser Metal Deposition include the production of near-net-shape parts, coating, joining, feature addition and, above all, repairs. This potential makes the technology interesting not only for applications on earth, but also for use in space. In the case of future space missions to Mars and beyond, the process can be used to react much more flexibly to emergencies and the total mass of spare parts on the spaceship can also be significantly reduced. This work shows the research project in which Laser Metal Deposition with metal powder for operation under the environmental conditions of space is being researched for the first time. For this purpose, the experiment is placed in the Einstein-Elevator (next generation drop tower). While the Einstein-Elevator performs a vertical parabolic flight, the experiment carrier is in free fall and the samples can be manufactured under microgravity. These samples should provide information about the influence of gravity on manufacturing and how it may need to be adjusted for an optimal process. In addition, this work provides an insight into the new development of a powder feeder that can convey powder in a targeted manner in zero gravity.
