The master's thesis investigates the effect of temperature on the fatigue life of 3D-printed structures made from polyether ether ketone (PEEK) under vibrational loading. The process began with the design of the specimen, followed by 3D-printing of the samples, and finally experimental testing performed on an electrodynamic shaker equipped with a temperature chamber. Based on the experimental data, a numerical fatigue life estimation was carried out using Dirlik's method and optimization of the parameters in Basquin's equation for different ambient temperatures. The results indicated improved fatigue resistance of PEEK at lower temperatures.
