Summary:The article studies the surface properties of PLA material prepared by additive technology, i.e. 3D printing. Samples with a square test area were printed by FFF technology. After 3D printing, the surface texture of the samples was evaluated in terms of microgeometry.Tribological tests were performed on the samples. The surface of the samples was cyclically stressed with the same load, always on the same path. Cyclic loading of the surface was performed on a UMT Bruker tribometer. The tribological properties between the sample surface and the test specimen in the shape of a ball were studied during the reciprocating motion. In particular, the coefficient of friction was measured and evaluated. The ball material was PTFE and Polypropylene.The wear parameters of samples and balls were documented and evaluated. The results of the tests are the load dependencies on the wear of the PLA material and the test specimens.
