“…─ Pitting: Hertzian pressure is too high with superimposed shear stress; pitting is the result of material fatigue in the near-surface area. The pitting is also caused by the shear stresses and the thermal stresses due to the sliding of the flanks [7]. ─ High wear: Low wear resistance or a highly abrasive surface of the friction partner; caused in part by chipping and in part by abrasion.…”

This paper describes the production, quality and tests of plastic gears made by fused filament fabrication (FFF). Different 3D printers of low and high quality and four different materials were tested: PLA, ABS, PA and PA carbon fiber composite. After optimizing the print parameters, various gears were manufactured and tested. The geometry and the test procedure were executed based on the VDI 2736 standard. This paper is a feasibility study of the fatigue strength of different gears. There is no material data set for the specific FFF-Materials and certain printers. The results show, that the quality of the printing process and the accuracy of the geometry are not responsible for the failure mode. The most important parameter is the friction coefficient of the different materials. Due to friction the tooth root will heat up and effect the material properties. PLA gears failed due to the low melting temperature, whereas ABS and PA gears failed on tooth root fracture.
