“…UCST and LCST are critical temperatures above and below polymers that get miscible, respectively. [295][296][297][298][299] TRPs have shown broad application prospects in the AM technology, due to their shape-changing abilities at a specific temperature. [300][301][302] For instance, Wang et al [301] used PCL/ thermoplastic polyurethane (TPU)-based SMP composites to develop a bionic gripper, which responded to heat stimulus, as illustrated in Figure 7A The study revealed that PCL/TPUbased thermo-responsive composite exhibited excellent shapememory recovery ratio (81.1 %), shape-memory fixity (100%), and stable shape-memory performance.…”

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.

“…Such NCGs are formed from NPs that are similar to those used in the NP–NP group (and are described in Section 2.2), however, they are crosslinked in a colloidal network by using additionally added low- or high-molecular weight crosslinking molecules. This class of NCGs includes both physically 34 and chemically crosslinked 14 gels. Biological or synthetic polymer crosslinkers are extensively used for the preparation of such NCGs.…”

“…When G 0 and G 00 are equal, the material is at a critical point of solid-liquid transition. 135 Recently, a PVA/CNF composite ink with shear thinning behavior that could be written directly at room temperature was proposed, 115 enabling precise control of machinability and shape retention (Fig. 7c).…”

“…160 A range of studies have compared and analyzed the distinctions between grafting PNIPAM onto nanocellulose and directly blending them to create hydrogels. 135,160,161 While the physical blending technique is simple, hydrogels prepared through this method may experience partial gelation and phase separation due to non-uniform mixing after surpassing the LCST, in comparison to covalent grafting (Fig. 8b).…”

“…Furthermore, the volume change of PNIPAM grafted CNCs before and after the LCST is minimal, rendering it suitable for wound dressings and implants. 135 In addition, nanocellulose modified by CD, 70,71 xyloglucan, 162 collagen, 163 and block copolymers (such as Pluronic F127, 117 PCLA, 132 etc.) has also been reported for temperature-responsive hydrogels for use in biomedical applications.…”
