Abstract-The Fused Deposition Modeling (FDM) process is widely used in additive manufacturing due to its cost-effectiveness and design flexibility. However, optimizing the print speed without compromising material consumption and surface quality remains a critical challenge. This study focuses on optimizing print speed, infill pattern, and wall count using the Design of Experiments (DOE) methodology in Minitab to achieve an optimal balance between printing time, material usage, and surface finish. The research evaluates the impact of these parameters on printing efficiency through a structured Taguchi experimental design approach, allowing for the identification of parameter settings that minimize print time while ensuring adequate part strength and surface smoothness. Various infill patterns (rectilinear, honeycomb, gyroid, and concentric), wall counts (single, double, and multiple shells), and print speeds were tested to determine their influence on material deposition rate, layer bonding, and overall print quality.
