Özet
Understanding the operational parameters that affect the strength of 3D-printed objects is fundamentally pursued in additive manufacturing. In this study, the effects of 3D printing parameters on the hoop strength of Polylactic Acid (PLA) rings are investigated, utilizing the Taguchi method for optimization. Analysis of Variance (ANOVA) is performed to uncover relationships between variables, while regression analysis is utilized to assess the compatibility of the experiments. The results show that all the 3D printing parameters are statistically significant. However, it is noted that the printing speed, temperature, and build plate temperature have a lower impact compared to infill density, which is the most important parameter on the apparent hoop strength. The most effective parameter configuration includes 100% infill density, a 65°C bed temperature, a 220°C extruder temperature, and a printing speed of 100 mm/s, resulting in a remarkable 36.1% increase in hoop strength compared to less favorable settings. Further optimization leads to an ideal combination of parameters that yields a maximum hoop strength of 48.6268 MPa, with a predictive accuracy demonstrated by a minor percentage error of 0.65% compared to the experimentally obtained value of 48.31 MPa. This research underscores the potential of Taguchi optimization in enhancing the apparent hoop strength of 3D-printed rings. The findings hold promise for optimizing FDM processes across various applications in additive manufacturing. © 2024 Praise Worthy Prize S.r.l.-All rights reserved.
