Influence of various input factors on the compressive strength properties of 3D printed carbon fiber reinforced PETG samples using Taguchi analysis

This study investigates the effect of different input variables on the compressive strength of 3D printed carbon fiber reinforced PETG samples by Taguchi Analysis, a robust statistical technique for optimizing complex processes. Mainly, this work reveals the influence of infill pattern and infill ratio together with temperature at the nozzle on the compressive strength of printed samples. The results indicate that the line infill pattern, an infill ratio of 60%, and a temperature of 230 °C at the nozzle improve the compressive strength. The study shows that this compression strength was primarily affected by the proportion of the infill material arrangement. More specifically, increasing the ratio of infill and using other kinds of patterns are helpful to enhance mechanical properties like strength. Nozzle temperature has a minimum effect on compressive strength among all the variables studied. Overall, this research also contributes significantly to improving the efficiency of 3D printing processes using Carbon fiber-reinforced PETG materials.
