Abstract:
Advancements in space repair technology are essential for extending mission longevity. This research investigates lightweight robotic cold spray additive manufacturing (CSAM) for repairing freeform components of damaged orbital equipment, offering a versatile, resource-efficient solution for microgravity environments. Focusing on copper—a critical material for thermal and electrical conductivity in spacecraft—the study examines key process parameters such as nozzle standoff distance, gas pressure, and temperature. By systematically analysing their effects on pososity, this work aims to identify optimal conditions for reliable on-orbit repairs. The integration of CSAM not only enhances mission safety and reduces costs but also supports the principles of a circular economy in space exploration by minimizing waste and maximizing resource utilization. This research advances the capabilities of CSAM for sustainable space applications, contributing to the long-term success of space missions.
