Abstract: The purpose of this study is to investigate the influence of the printing temperature on several tribological parameters. Design/methodology/approach: Polylactic acid (PLA) samples are produced at different printing temperatures. Results for the influence of the printing temperature on linear wear, wear intensity, wear resistance, roughness and microhardness in condition of reverse sliding friction of tribosystems with two different types of counterbodies were obtained. Findings: In view of the experiments performed and a thorough analysis of the data obtained, it can be concluded that the printing temperature of PLA parts is directly related to their wear resistance – the higher the printing temperature, the greater the wear resistance, i.e. when making PLA machinery elements (which are working under conditions of friction and wear, e.g. gears, plain bearings and so on), it is appropriate to print them at a higher temperature.
