Abstract: The paper examines the parameters of abrasive wear and wear resistance of three types of polymeric materials from different manufacturers – PETG, PLA and Tough PLA, obtained by 3D technology. The materials were tested in four modes of friction – without and with lubricant grease Litol 24 and at two sliding speeds. Results and dependences for mass wear, wear rate, wear intensity and wear resistance of each material in the four friction modes were obtained. The following materials have been found out to have the best anti-wear properties: at dry friction – PETG, at sliding speed v = 0.25 m/s, at sliding speed v = 0.92 m/s – PLA; at limit lubrication with Litol 24 – PETG grease at sliding speeds v = 0.25 m/s and v = 0.92 m/s. The results are original and have not yet been published in other editions.
