This thesis explored two areas how the structural characteristics of ULTEM 9085 changed after exposure UV radiation and the required design of an ULTEM 9085 beam to be 3-D printed in microgravity. ULTEM 9085 dogbones were printed and exposed to several Sols worth of UV radiation in a vacuum chamber. Axial testing showed the ULTEM 9085 became stronger as a result of the vacuum and more brittle as a result of the UV radiation. Simultaneously, a cylindrical beams internal structure was optimized based on several possible loading configurations expected during printing on orbit.
