Abstract-In Fused Deposition Modeling (FDM), support structures are essential for printing overhanging and complex geometries. However, excessive support material increases printing costs, material wastage, and post-processing time. This study focuses on optimizing support patterns and part orientation using Design of Experiments (DOE) methods to minimize material usage while maintaining structural stability during printing. The study evaluates two commonly used support structures: normal (grid-based) and tree-like supports, along with different part orientations to determine their impact on material consumption and overhang stability. The Taguchi DOE method is implemented to systematically analyze the influence of orientation and support type on key parameters such as printing time, support volume, and ease of removal.
