AB This paper presents the results of a comparative evaluation of the tensile strength behaviorsof parts obtained by additive manufacturing using fused filament fabrication (FFF) technology.The study investigated the influences of the deposition printing parameters for both polymers andfiber-reinforced polymers. Polymeric materials that are widely used in FFF were selected, includingacrylonitrile butadiene styrene (ABS), polylactic acid (PLA), and nylon. Carbon and glass continuousfibers were used to reinforce the nylon matrix in composite materials. The study utilized twomanufacturing methods. Polymers were manufactured using an Ultimaker 2 Extended+ device andthe fiber-reinforced polymer specimens were obtained using a Markforged Mark Two printer. Theentire set of specimens was eventually subjected to destructive monoaxial tensile tests to measuretheir responses. The main goal of this study was to estimate the effect of the different infill patternsapplied (zig-zag, concentric, and four different orientations lines) on the mechanical properties ofpure thermoplastic materials and reinforced polymers. Results show a spectacular increase in thetensile stress at break, which for polymers reaches an average value of 27.53 MPa compared to94.51 MPa in the case of composites (increase of 70.87%). A similar increase occurs in the case oftensile stress at yield with values of 31.87 MPa and 105.98 MPa, respectively, which represents anincrease of 69.93%. The influence of the infill of the fiber is decisive, reaching, in the 0-0 arrangement,mean values of 220.18 MPa for tensile stress at break and 198.26 MPa for tensile stress at yield.
