The development of modern manufacturing technologies related to the ongoing industrial revolution Industry 4.0, is largely related to the dynamic development of materials chemistry. This means that currently 3D printing technologies allow the production of physical models using newer materials with better properties and application in new industrial sectors. The article presents the results of tribological tests of the bio-medical material under the trade name MED610, which shows biocompatibility for medical and dental purposes. The paper presents the results of measurements of tribological models of samples designed and manufactured in the shape of rings. Using the variable friction parameters, the wear process was described in the pressure-rotational speed (P-V) system. Moreover, the friction coefficient and wear measured by using the linear method were analyzed. The paper also presents a metrological analysis carried out with the application of an optical profilometer on the surface of the samples after pressing at the contact point of the surface during the test. The preliminary review of the test results showed that the MED610 material exhibited relatively good abrasion resistance. However, it cannot be employed for heavily loaded friction nodes, and in the PV diagram even at a relatively small value, the sample models were destroyed.
