As part of the work, tests were carried out to determine the mechanical properties of PEEK and KIMYA PEKK-A materials. The test samples were prepared using the incremental FDM method, it is a 3D printing involving the formation of a liquid thermoplastic. Two types of tests were carried out. The first test consisted in performing a uniaxial tensile test on an MTS Criterion Model 43 testing machine. During the test, the displacement was measured using two measuring devices - an extensometer and a digital image correlation system. Based on the test, Young's modulus, Poisson's number and maximum breaking force were determined. The value of the maximum breaking force was used to determine the load levels for the fatigue test, which was performed on the MTS Acumen model 12 dynamic testing machine. On the basis of the dynamic tests, the Wöhler fatigue curves were plotted.
