“…Table S1 (Supporting Information) shows the compositions that were used to measure the effect of AuNPs concentration on the efficiency of photothermal conversion. In this research, we used “phr” (parts per hundred parts of resins) as the unit of AuNPs concentration in resin of poly (EA‐IBOA‐HDDA), and it was calculated from the following equation [ 24 ]

\begin{matrix} phr = \frac{m_{AuNPs}}{m_{resin}} \times 100 % \end{matrix}

4D printing is based on 3D printing of objects that can change their shape upon a proper triggering. Here, a novel approach is reported for fabricating programmable 3D printed objects composed of shape‐memory polymers (SMPs) that are activated by light. The light activation of the movement and shape morphing are based on combining gold nanoparticles (AuNPs) as photothermal converters with acrylate‐based printing compositions that form an SMP with tunable transition temperatures. The shape change of the printed objects is triggered by remote irradiation with a low‐cost LED light at a wavelength specific to the surface plasmon resonance of the embedded AuNPs. The light is converted to heat which enables the shape transition when the temperature reaches the Tg of the polymer. Excellent SMP properties are achieved with shape fixity and recovery ratios over 95%. This material composition and triggering approach enable fabricating programmable light‐activated 3D printed structures with a dual transition while tuning the concentration. Furthermore, numerical simulations performed by finite‐element analysis result in the excellent prediction of the shape‐memory recovery. The presented approach can be applied in remotely controlling morphing, mainly for applications in the fields of actuators and soft robotics.

While shape memory alloys (SMAs) and shape memory polymers (SMPs) can already be found in diverse applications, shape memory textiles are less often used. Nevertheless, they are regularly investigated. Typical ways to produce shape memory textiles (SMTs) are introducing shape memory wires, printing shape memory polymers on them (“4D printing”), or using textile materials such as poly(lactic acid) (PLA) which show shape memory properties on their own. This review gives a brief overview of these technological possibilities and possible applications of shape memory textiles.

“…This shape recovery can be useful toward applications such as soft robotics, biocompatible scaffolding, drug delivery, and recoverable load-bearing frameworks. [1][2][3][4][5][6][7][8] SMPs are materials capable of being physically deformed and fixed to a "temporary" shape. Upon external stimuli such as temperature, pH, light and electromagnetic fields, SMPs recover from the deformation and return to a "permanent" shape configuration.…”
