Since its first apperance in 1999, the CubeSat standard has made access to space more affordable and easier for small realities such as universities and research institutions. The cost of a CubeSat already dropped a lot thanks to the availability of Off The Shelf components, but the structure is still an expensive part if you want it customized. A viable option to reduce its costs and increase customization is to produce it using Additive Manufacturing methods. Following this introduction, in the first part of the thesis, the author has designed two different 1U CubeSat structures that have then been manufactured using the Fused deposition modelling (FDM) process.
