Liquid Crystal Elastomer Lattices with Thermally Programmable Deformation via Multi‐Material 3D Printing

Abstract: An integrated design, modeling, and multi‐material 3D printing platform for fabricating liquid crystal elastomer (LCE) lattices in both homogeneous and heterogeneous layouts with spatially programmable nematic director order and local composition is reported. Depending on their compositional topology, these lattices exhibit different reversible shape‐morphing transformations upon cycling above and below their respective nematic‐to‐isotropic transition temperatures. Further, it is shown that there is good agreement between their experimentally observed deformation response and model predictions for all LCE lattice designs evaluated. Lastly, an inverse design model is established and the ability to print LCE lattices with the predicted deformation behavior is demonstrated. This work opens new avenues for creating architected LCE lattices that may find potential application in energy‐dissipating structures, microfluidic pumping, mechanical logic, and soft robotics.
