RESEARCH OF TRIBOLOGICAL PROPERTIES OF POLYLACTIDE (PLA) IN THE 3D PRINTING PROCESS IN COMPARISON TO THE INJECTION PROCESS
Journal Title: Tribologia - Year 2019, Vol 283, Issue 1
Abstract
This article presents the results of studies on the tribological properties of linear wear and kinetic friction of polylactide processed by 3D printing (FFF) and injection moulding. Research was conducted on a pin on disc apparatus, and the test specimens used were polylactide cylinders with the counter specimen of C45 steel disc. Research was planned and executed with the planned experiment method for two variables: velocity of the counter specimen and pressure. The range of specified values was in the following sections: p = 0.2;0.6 MPa and v m s = 0.2;1.0 . The conducted experiment had a target of defining the influence of a somewhat new method of 3D printing on the tribological properties of materials that might find application in prototyping plain bearings.<br/><br/>
