Abstract

Dimensional accuracy is a crucial aspect of 3D printing technology based on Fused Deposition Modeling (FDM), as deviations from the intended dimensions may lead to product malfunction and difficulties in component assembly. Such inaccuracies are generally influenced by various process parameters during 3D printing. This study aims to evaluate the effects of four main FDM parameters layer height, infill density, print speed, and nozzle temperature on the dimensional accuracy of printed parts using PLA+ material. The primary focus of this research is to enhance dimensional accuracy. To achieve this objective, the Taguchi design of experiments method was employed, offering a structured and efficient approach to optimizing process parameter settings while minimizing the required number of experiments. An L27 orthogonal array matrix was selected to analyze the influence of parameters at three levels. Based on the analysis of signal-to-noise (S/N) ratios and response data, the optimal parameter combination was identified as follows: layer height of 0.1 mm, infill density of 100%, print speed of 40 mm/s, and nozzle temperature of 210°C. Confirmation tests with these settings demonstrated a significant improvement in dimensional accuracy, with average measurements of 11.73 mm on the X-axis, 7.08 mm on the Y-axis, and 21.08 mm on the Z-axis. These results confirm that the selected parameter configuration is capable of ensuring dimensional stability and consistency.

Abstract

The rapid development of manufacturing technology is marked by the emergence of Additive Manufacturing (AM) or 3D Printing technology. This study aims to analyze the effect of layer height and printing speed on the mechanical strength of PETG material using the Fused Deposition Modeling (FDM) method. The printing process was carried out using an Ender 3 Pro 3D printer with process parameter variations of layer height (0.2, 0.3, and 0.4 mm) and printing speed (40, 50, and 60 mm/s) arranged according to the Taguchi L9 (3²) experimental design. eSUN PETG filament was selected due to its compatibility with the test requirements. The test specimens were fabricated according to the ASTM E23 standard with dimensions of 55 × 10 × 10 mm for impact strength testing. The results show that printing speed has a more significant influence on mechanical strength compared to layer height. The Taguchi analysis indicates that layer height contributes the most to the mechanical performance, followed by printing speed. The optimal combination was obtained at a layer height of 0.2 mm and a printing speed of 40 mm/s. Overall, the study highlights the critical role of process parameter optimization in improving the mechanical strength of 3D printed PETG thermoplastic materials.
