Abstract-– In Material Extrusion (MEX) additive manufacturing, the infill pattern significantly affects printing time, material consumption, and mechanical properties of the printed parts. This study investigates the impact of different infill patterns on these key performance indicators using statistical optimization techniques. The research aims to identify an optimal infill configuration that balances strength, weight, and print efficiency while minimizing material waste. Various infill patterns such as rectilinear, honeycomb, gyroid, and concentric were analyzed, and their effects on printing time and material consumption were evaluated using Design of Experiments (DOE) and Taguchi optimization methods. The study also examines the role of infill density and pattern complexity in determining the overall build efficiency. Results indicate that complex lattice structures (e.g., gyroid) tend to provide better strength-to-weight ratios but increase printing time and material usage. Conversely, simpler patterns like rectilinear offer faster prints with reduced material consumption but may compromise mechanical integrity.Additionally, the porosity between layers due to infill selection was analyzed. process.
