Abstract
This study analyzes the effect of 3D printing process parameters based on Fused Deposition Modeling (FDM) on void formation and wear rate in nylon bearings. Three main parameters tested were layer height, nozzle temperature, and infill density, each at three levels with a Taguchi L9 (3³) experimental design. Voids were analyzed through optical microscope images using ImageJ, while the wear rate was determined based on the mass difference before and after the test. Data were analyzed using Taguchi, ANOVA, and Grey Relational Analysis (GRA) methods to obtain the optimum multi-response combination. The results showed that infill density had the greatest effect on void formation with a contribution of 90% (p = 0.003), while layer height was dominant on the wear rate with a contribution of 71% (p = 0.021). The optimum combination (layer height 0.12 mm, nozzle 270°C, infill density 100%) resulted in a 54% reduction in voids and a 22% reduction in wear rate compared to the worst condition. The predicted GRG value of 0.95 and the actual value of 0.94 indicate the model is quantitatively valid. This research contributes to improving the efficiency and wear resistance of additively manufactured polymer components.
