Enhancement of Process Parameters for Mex Process Using Cura 5.9.0 and Minitab Softwares

Abstract-The Material Extrusion (MEX) process, commonly known as Fused Deposition Modeling (FDM), is widely used for manufacturing complex geometries with minimal material wastage. However, optimizing key printing parameters is crucial for improving efficiency while maintaining print quality. This study focuses on enhancing the MEX process using Cura 5.9.0 and the B to optimize layer height, line width, and wall count, aiming to reduce print time and material consumption. The Taguchi DOE method was employed to systematically analyze the effects of these parameters on printing performance. A set of experiments was conducted by varying layer height, line width, and wall count within practical limits. The primary objectives were to minimize printing time and optimize material usage while maintaining structural integrity. Print time and material consumption were recorded for each experiment, and statistical analysis was performed using Minitab to determine the optimal parameter combination. The results show that layer height significantly influences printing time, as higher layer heights reduce the number of layers but may impact surface quality. Line width affects material flow and print strength, while wall count directly impacts material consumption. The optimized parameter settings achieved a significant reduction in print time and material usage, ensuring an efficient balance between speed, material economy, and part durability. This study demonstrates that using Cura 5.9.0 in combination with DOE techniques provides a structured methodology for enhancing the efficiency of the MEX process. The findings are beneficial for industries and researchers seeking to optimize print settings, reduce operational costs, and improve sustainability in additive manufacturing.
