In this talk, we’ll explore the application of hybrid manufacturing to injection mold tools for both modification and repair, demonstrating a circular economy where tools can be modular, reusable, and rapidly modified. Hybrid manufacturing uses machine tools that combine additive and subtractive operations, and provide particular value to the modification and life extension of mold tools. We'll demonstrate a workflow using Autodesk software to (a) identify unwanted features or damage on a mold, (b) capture physical geometric data, (c) program processes to remove and repair features and damage, (d) redeposit material, and (e) machine new features. We'll demonstrate both the digital and physical aspects of the workflow, and aim to present the final physical output—a brand-new injection-molded component, made in the Autodesk Moldflow Laboratory in Kilsyth, Australia. This project is a collaboration between the Manufacturing Demonstration Facility at Oak Ridge National Laboratory and Autodesk.
