Abstract
FDM 3D printing technology is widely used to make PLA bearing, but the main problems that arise are voids and wear. This study aims to optimize process parameters in order to reduce voids and lower the wear rate on PLA bearing. The parameters varied included infill density (60%, 80%, 100%), layer height (0.10 mm; 0.15 mm; 0.20 mm), and nozzle temperature (190°C, 200°C, 210°C). The experiment was designed using the Taguchi method with an L9 orthogonal array. Void analysis was performed using an optical microscope processed with ImageJ software, while wear testing was conducted through tribology testing on a CNC machine with a load of 2 kg and a speed of 500 rpm. Layer height proved to be the most influential factor on wear, while infill density contributed most to void formation. Nozzle temperature had a smaller effect but still influenced print quality. Based on Grey Relational Analysis (GRA), the best combination that provided the highest GRG value was 60% infill, 0.10 mm layer height, and 190°C nozzle temperature. The p-value < 0.10 confirmed that the optimization results were significant at a 90% confidence level. Optimization of printing parameters using Taguchi–GRA has been proven to minimize voids and reduce wear rates, thereby improving the mechanical quality of PLA bearings and enabling their use not only as prototypes but also as functional components. Keywords: 3D printing, Taguchi method, Grey Relational Analysis, void, wear
