4D printing is an emerging fabrication technology that enables 3D printed structures to change configuration over “time” in response to an environmental stimulus. Compared with other soft active materials used for 4D printing, shape‐memory polymers (SMPs) have higher stiffness, and are compatible with various 3D printing technologies. Among them, ultraviolet (UV)‐curable SMPs are compatible with Digital...
4D printing is a multifunctional additive manufacturing technology that enables 3D‐printed structures to change shape over the fourth dimension, time. In article number 2101298, Qi Ge and co‐workers report mechanically robust and UV‐curable shape‐memory polymers, which are 3D‐printable, highly deformable, and fatigue‐resistant, and demonstrate great potential in aerospace and other engineering applications...
