Topology-Optimized Spool Holder | Autodesk Fusion 360 Project This project showcases the design and topology optimization of a spool holder using Autodesk Fusion 360, focused on achieving maximum strength-to-weight efficiency for additive manufacturing applications. Project Overview The goal was to create a filament spool holder that uses minimum material while maintaining structural rigidity under operational loads. In Fusion 360’s Simulation workspace, boundary conditions were defined with fixed supports at three mounting points and a central load simulating spool weight and operational stresses. Topology Optimization Workflow Using Fusion 360’s cloud-based solver, shape optimization was performed to minimize mass and maximize stiffness. The resulting stress distribution (red = high stress, green = low stress) revealed the optimal load path, guiding material removal and the retention of critical structural regions. After optimization, the mesh was refined in the Design workspace for manufacturability and aesthetics, ready for 3D printing. Final Design & Key Benefits The final design exhibits organic, truss-like structures, concentrating material only where necessary — achieving a significant mass reduction compared to the original block model. This leads to improved performance, reduced material usage, and greater sustainability in production.
