Topology Optimization (TO) is a mathematical method for optimizing material layout within a defined design space, considering specific loads, boundary conditions, and constraints to maximize system performance. This nonparametric optimization technique identifies and removes regions that do not contribute to the stiffness of the part or the flow of force. Design Objectives: Investigate material properties and techniques for creating a rigid façade system using additive manufacturing via robotic 3D printing. Enable economical production of lightweight components, allowing for complex geometric forms. Achieve a zero-waste fabrication process. Incorporate recyclable materials for a more sustainable built environment. Minimize transportation costs and reduce building weight. Enhance structural efficiency and sustainability by minimizing material use while optimizing façade coverage. Create multifunctional spaces that offer an engaging and exploratory user experience. This research project couples Topology Optimization (TO) with robotic 3D printing of plastic to develop an ultra-lightweight, fully recyclable, and materially efficient building envelope system. The optimization parameters include wind and gravity loads, as well as key connection points to the building structure. A significant challenge in large-scale pellet extrusion is the precise start and stop control of the extrusion process. This project advances the field by developing tool-path strategies and hardware control paradigms, enhancing the fidelity of the final printed part.
