Abstract-Additive Manufacturing (AM) using material extrusion processes, such as Fused Deposition Modeling (FDM), often requires support structures to ensure the stability of overhanging or complex geometries during fabrication. However, the use of support material increases material consumption, printing time, and post-processing effort, ultimately raising production costs. This project focuses on optimizing the orientation of parts during the manufacturing process to minimize the use of support material while maintaining the structural integrity and quality of the final product .Fusion 360 was used to simulate the manufacturing process by evaluating various part orientations. By analyzing the overhang angles, build directions, and contact areas requiring supports, optimal orientations were identified. The optimization process considered parameters such as material usage, print time, and surface finish quality. Additionally, simulations were conducted to evaluate the impact of orientation changes on part strength and dimensional accuracy. The study revealed that strategic orientation adjustments could significantly reduce support material wastage by minimizing the number and size of overhangs. For instance, aligning the part’s geometry with the build platform or leveraging self-supporting angles helped achieve material efficiency. The outcomes demonstrated that reducing support material by optimizing orientation not only improves material utilization but also enhances sustainability in AM processes. This research highlights the importance of orientation optimization in material extrusion processes and showcases the potential of simulation tools like Fusion 360 to refine the manufacturing process, enabling cost-effective and resource-efficient production.
