5. Conclusions

Mechanical properties of short fiber-reinforced polymeric 3D-printed materials were compared. The highest strength is found in samples made of ABS and additionally reinforced with various fibers. This strengthening made a significant contribution to strengthening the material and increasing its resistance to mechanical stress. Reinforcement of the PA12 material resulted in a significant reduction in plastic deformation, making it more suitable for applications where strength and stiffness are important. However, the PA12 samples made with an infill angle of 90° showed the formation of plastic deformations. This may indicate that the fiber is not working effectively in this case, since it is not aligned in the direction necessary to strengthen the material. This observation highlights the importance of proper orientation and placement of reinforcing fibers during printing to achieve optimal mechanical properties of the additively manufactured parts.
