Reducing the volume of support structures is a critical approach in saving materials and budgets of Additive Manufacturing, and tree structure is an effective design for this purpose. Although a few literatures and commercial software have been devoted to developing tree-supports, those tree-supports are generated based on geometry optimization or user-defined parameters, which cannot guarantee a minimum volume with the physical constraints. To address this issue, we propose a set of formulas for stably growing the tree-supports with physical constraints based on 3D printing experiments using FDM machines, and a volume minimization mechanism using a hybrid of particle swarm optimization (PSO) method with geometric constraints and a greedy algorithm. We show that this combination is effective in reducing the volume of tree-supports and the simulations show that the curves of volumes are monotonically descent to a constant after within a short time, and our experimental results show that the models with support structures can be manufactured stably.
