Abstract

Contemporary actuation systems are increasingly required to perform multiple tightly-coupled functions analogous to their natural counterparts; e.g., the ability to control displacements and high-resolution appearance simultaneously is required for mimicking the camouflage seen in cuttlefish. Optimizing and fabricating integrated actuation systems is challenging due to the combined complexity of generating high-dimensional designs, and developing multifunctional materials and their associated fabrication processes. Here we present a complete toolkit consisting of multiobjective topology optimization (for design synthesis) and multimaterial drop-on-demand 3D-printing for fabricating complex actuators ($>10^6$ design dimensions). The actuators consist of soft hinges and rigid plates made of acrylate polymers and a magnetic nanoparticle/polymer composite (MPC) that responds to a magnetic field. The multi-objective topology optimizer assigns materials for individual voxels (volume elements) while simultaneously optimizing for physical deflection and high-resolution visual properties. Our work demonstrates that unifying a topology optimization-based design strategy with a multimaterial fabrication process enables the creation of complex actuators and provides a promising route towards automated, goal-driven fabrication.
