Wear behavior of additive manufactured polymer-polymer sliding combinations

For industrial applications, additive manufacturing becomes more and more important due to its unrivaled design and materials freedom. In this light, additively manufactured polymer-polymer sliding combinations gain increasing interest for manifold tribological applications. This potential can be fully exploited, e.g., by using tribologically tailored compounds. For additive manufacturing not only the sliding combinations but also the understanding of the influence ofprinting parameters are important. Thus, this work is a first investigation of commercially available tribological compounds regarding their wear behavior by means of the ball-prism wear test. On that basis, influences of printing orientation and material combination on the wear behavior are investigated. In addition, interactions of these parameters will be discussed. Finally, the challenges of test specimen production as well as wear measurements are considered. © 2021 Expert Verlag. All rights reserved.
