This study deals with the commercial FDM material, ColorFabb XT-CF20, its fabrication on a desktop FFF printer, Prusa I3 Mk2 and thermal post-processing by annealing. Two sample specimens were fabricated by 3D printing, while one of them was subjected to annealing process. The specimens were subsequently analyzed for their thermal and microscopic properties in order to observe the changes in glass transition temperature (Tg), crystallinity and mesostructural properties as the result of thermal post-processing, i.e., annealing. The results showed that annealing can be used with this material with the potential to improve its mechanical characteristics. The observed changes in mesostructure showed that the cooling process requires prolonged time in order to minimize geometrical deformations.
