“…In 4D printing, the printed object is designed to change its shape or function over time when exposed to specific environmental conditions or external stimuli. The process typically involves printing a structure using materials with special properties, such as shape-memory polymers [138][139][140][141] or composites with responsive elements [142][143][144][145], ceramics are also finding applications [146][147][148]. These materials are programmed to react to external factors like heat, moisture, light, or magnetic fields.…”

Stimuli‐responsive polymers (SRPs) are special types of soft materials, which have been extensively used for developing flexible actuators, soft robots, wearable devices, sensors, self‐expanding structures, and biomedical devices, thanks to their ability to change their shapes and functional properties in response to external stimuli including light, humidity, heat, pH, electric field, solvent, and magnetic field or combinations of two or more of these stimuli. In recent years, additive manufacturing (AM) aka three‐dimensional (3D) printing technology of these SRPs, also known as four‐dimensional (4D) printing, has gained phenomenal attention in different engineering fields, thanks to its unique ability to develop complex, personalized, and innovative structures, which undergo twisting, elongating, swelling, rolling, shrinking, bending, spiraling, and other complex morphological transformations. Herein, an effort has been made to provide insightful information about the AM techniques, type of SRPs, and their applications including, but not limited to tissue engineering, soft robots, bionics, actuators, sensors, construction, and smart textiles. This article also incorporates the current challenges and prospects, hoping to provide an insightful basis for the utilization of this technology in different engineering fields. It is expected that the amalgamation of 3D printing with SRPs would provide unparalleled advantages in different engineering arenas.This article is protected by copyright. All rights reserved.
