Abstract. Creation of mechanical parts by composite materials with specific requirements can be facilitated nowadays by employing additive manufacturing (AM) techniques. Especially, Fused Filament Fabrication (FFF) process is a particularly simple but effective method for this purpose for polymers and polymer composites. However, the limitations of printing speed due to the inherent characteristics of this process constrain the high levels of productivity which are necessary in industry. Thus, in this work the effect of high printing speeds on the mechanical properties of FFF-printed composite ABS-Kevlar specimens was evaluated in order to determine the potential limits of printing speed values which can be used without deteriorating the mechanical properties of specimens. Tensile and compression tests were carried out for a comprehensive range of printing speeds and the results of different mechanical properties were analyzed. The findings indicated that the increase of printing speed can affect the tensile yield strength and UTS but its influence is negligible or minimal on other mechanical properties, implying that an increase of productivity is possible, at least up to a limit, without a detrimental effect on part strength.
