Abstract Scope |
OpenVCAD is an open-source volumetric design compiler suited for multi-material design workflows including functionally graded meta-materials and lattice structures. In this presentation, we extend its capabilities to support tool-path-based 3D printers, enabling unprecedented control over functionally graded toolpaths. By leveraging dynamic adjustments in process parameters like feed rate, temperature, and mixture ratios, OpenVCAD allows for precise material grading along tool paths. We demonstrate the efficacy of OpenVCAD with case studies involving mixing extruders, temperature-responsive materials, and variable stiffness foams. Additionally, we will detail how OpenVCAD can directly interface with finite elements and map multi-material gradients based on simulation results. We aim to demonstrate the versatility of OpenVCAD across a wide variety of printing practices. Our work showcases how OpenVCAD empowers users to design and fabricate complex multi-material objects, unlocking new possibilities in multi-material additive manufacturing. |
