| Abstract Scope |
Magneto-active elastomers (MAEs) are smart materials capable of shape programming, large deformations and large magnetic actuation forces when exposed to an external magnetic field. Applications of these capabilities include actuators, soft grippers and a variety of other shape-changing devices. Additive manufacturing processes, such as the novel Reactive-Extrusion Additive Manufacturing (REAM) process utilized in this work, are capable of spatially customizing the composition and magneto-active response of these materials by blending multiple feedstocks on demand. Prior work has demonstrated this capability via physics-based modeling and experimental fabrication, but the printing capabilities of the underlying process have not been considered. The methodology of this work consists of creating a user-defined part and shape matching with an accompanying target profile. This part is defined by multiple raster layers with a magnetic fraction function that models the transient response of the REAM process alongside Euler-Bernoulli theory to produce manufacturable magneto-active complex parts with precision. |
