The samples were manufactured using the fused filament fabrication technique. The mechanical properties of samples made of reinforced filaments were compared to those made of pure polymeric materials in uniaxial tensile tests. The elastic modulus, tensile strength and resilience were determined. Samples reinforced with short fiber showed an increase in strength characteristics compared to pure material. The influence of the diameter of the nozzle used for samples manufacturing on their mechanical characteristics and was established. © 2024 The Authors. Published by ELSEVIER B.V.

Introduction The additive manufacturing is one of the most promising engineering technologies. One of the commonly used 3D printing methods is fused filament fabrication, FFF (also called fused deposition modelling, FDM), which is based on placement of melted thermoplastic polymeric filaments following a predetermined path (Brenken et al., 2018; Ngo et al., 2018). This method allows to produce lightweight and durable parts with individual geometry.
