| contents | Deployable structures, essential across various engineering applications ranging from umbrellas to satellites, are evolving to include soft, morphable designs where geometry drives transformation. However, a major challenge for soft materials lies in achieving reliable actuation and stable shape retention in their deployed state. Drawing inspiration from biological growth processes, we demonstrate that irreversible plastic deformations can be leveraged to create cellular metamaterials with permanent morphing capabilities. By employing a simple actuation method, stretching and releasing the structure's ends, our approach facilitates the design of structures capable of sequential, multi-target configurations and mechanical multistability. Our methodology augments additive manufacturing to transform flat, printable designs into intricate 3D forms, with broad applications in consumer goods, healthcare, and architecture. |
