The purpose of this study is to manifest the mechanical properties of ABS FDM printed specimens, passing through macro and micro structures with their impact on the material properties of ABS polymer, with respect to applied industrial parameters. Two printing parameters where studied simultaneously, namely, printing temperature and extruder speed. Moreover, mechanical tests were applied on specimens in order to study their results and conclude the desired properties, the tests are tensile test and impact-charpy test. The Design of Experiments (DOE) full factorial approach was adopted. The tensile strength, elongation and modulus of toughness of the thermoplastic polymer were the responses measured to identify the most influencing parameter and the best settings. The experimental results show that an increase in the printing temperature increases both tensile strength and modulus of toughness, and decreases the elongation of the thermoplastic polymer. Compared to printing speed, the printing speed reduces tensile strength, elongation and modulus of toughness properties.
