Abstract Scope |
Reactive Extrusion Additive Manufacturing (REAM) is a process in which a multi-part thermoset resin is layered by a motion-controlled nozzle mixer. The initial liquid state of the material allows for the addition of magnetic particles into the neat resin which can be functionally graded in the final part. The functional grading unlocks the ability for shape actuation, via magnetic field stimuli, after the curing process is completed. The main challenge of functional grading is the large dead volume within the passive mixing system, which prevents rapid and accurate particle grading. To reduce this volume an active mixing nozzle, designed for the rapid mixing of neat and particle filled resin with the catalyst, is employed for more rapid, precise grading. The effectiveness of mixing and the accuracy of functional grading are tested by printing multiple geometries with their compositions validated through VSM analysis. |
