Abstract
Human space exploration is becoming a major target for space agencies lately. This interest is based on the will, some people may say need, to set a foot on places outside Earth and prove them viable and sustainable for humans. However, before doing so, space agencies want to be certain that those who will be sent will have everything day need in order to ensure the success of the missions. A major thread to this success is the, a priori, difficulty of suppling the astronauts with what they need when they need it. Seeking this objective, this project has worked on developing a sustainable 3D printing methodology to provide the astronauts with versatile spare parts as fast as possible. The chosen material has been Cellulose Acetate due to the fact that it can be extracted from crops which are likely be grown on long term missions allowing to a closed loop lifecycle. Moreover, Cellulose Acetate is a biocompatible material and accepts a wide range of fillers. In this work, combination of Cellulose Acetate solutions with different carbon-basedfillers has allowed us to produce electrically conductive parts which could perform different functions on demand. This work has proved that Cellulose Acetate printed parts can be totally reused without any loss of material for a Solvent Cast 3D printing process. Thus, Solvent Cast 3D printing of Cellulose Acetate based composites has proven a viable and promising methodology for space exploration
