Abstract
In this study, the optimization of 3D printing process parameters for the fabrication of CNT/ABS nanocomposites was investigated using the Taguchi method. The primary objective was to optimize the mechanical properties, weight, printing time, and material consumption of the fabricated parts. To achieve this, key printing parameters—including printing temperature, printing angle, infill percentage, printing speed, infill pattern, carbon nanotube (CNT) weight fraction, and layer thickness—were systematically examined to identify the most optimal configuration. Experimental results revealed that infill percentage and layer thickness had the most significant influence on tensile strength and Young’s modulus; specifically, increasing the infill percentage and decreasing the layer thickness led to notable improvements in these properties. Furthermore, by optimizing these parameters and precisely adjusting the printing angle, the part weight was reduced, and both printing time and filament consumption were optimized. Additionally, the ratio of strength to the product of weight, printing time, and filament length was introduced as an effective index for evaluating the overall printing performance.
