PLA MATERIAL SURFACE PROPERTIES EVALUATION PREPARED BY ADDITIVE TECHNOLOGY

Popis výsledku v původním jazyce

The article deals with tribological evaluation of surface properties and their changes in biodegradable material PLA (polylactic acid). On samples prepared using 3D FFF printing technology, with uneven filling density, printed on the Prusa printer. The surface texture of the samples was evaluated in terms of microgeometry, which was created by the process of 3D printing. The TalySurf CLI1000 was used to evaluate the texture. The surface texture was measured with an inductive touch sensor. Subsequently, the samples surfaces were cyclically stressed with a defined load always on the same path. Cyclic surface loading was performed and measured by a UMT Bruker tribometer. During the cyclic reciprocating motion, the tribological properties of the surface, especially the coefficient of friction, were studied. The values of applied loads were constant. Traces obtained during tribological testing were documented on an Olympus DSX 100 optical microscope. Trace parameters were verified by profilometric analysis on a TalySurf CLI1000. The values obtained, in particular the track widths, can be used to determine the wear coefficient.
