| Abstract Scope |
Functional grading of materials through extrusion-based processes such as Reactive Extrusion Additive Manufacturing (REAM) enables fabrication of designs with embedded complex behaviors. The difficulty of functional grading arises from constant changes and transitions between material compositions, leading to instabilities in the printing process and decreased part quality. Additionally, experimental characterization of materials and process tuning would be too costly, as the number of potential material compositions requested in functional grading is too large. As such, an on-demand resin characterization and process planning framework was developed to functionally grade magneto-active particles for a REAM process. This work presents the framework and its validation. Leave-One-Out validation (LOOV) and rheological measurements through viscometry were conducted to validate the characterization portion of the framework. A comparison of geometric fidelity of a framework-informed print with both a naďve approach print and single-resin print was conducted to validate the process planning portion of the framework. |
