As the capacity of compact battery technology for spacecraft missions continue to improve, small payloads are less constrained by power limitations, thus relatively high-power applications may be considered. AddCube is a mission to develop a platform, conforming to the 6U CubeSat Standard capable of demonstrating on-orbit Additive Manufacturing technology. A critical concern is the development and demonstration of a thermal management design that is capable of handling the significant waste heat generated by the high-power Additive Manufacturing payload while maintaining component temperatures throughout the spacecraft within an acceptable range. This effort includes a trade study for the evaluation of candidate technologies, an analytical model and analysis of spacecraft thermal management design, testing to compare payload isolation and non-isolation from the spacecraft chassis, experimental validation of the analytical model, and development of future work. The thermal management design includes α/ε = 0.0989 coated passive fixed radiators, a passive thermal storage unit utilizing Eicosane as the phase change material, with the support of active heaters to enable a 135W Additive Manufacturing payload to operate in a 100% duty cycle condition.
