“…Due to its capacity to take on its original shape again, a shape memory-based triboelectric nanogenerator (STENG) is also suitable for soft robotic applications [ 192 ]. Using shape memory materials to create soft robotic grippers using 4D printing methods has been the focus of various studies [ 193 , 194 , 195 , 196 ]. These grippers are highly flexible and can handle a variety of objects responding to an external stimulus such as heat.…”

The scientific community is and has constantly been working to innovate and improve the available technologies in our use. In that effort, three-dimensional (3D) printing was developed that can construct 3D objects from a digital file. Three-dimensional printing, also known as additive manufacturing (AM), has seen tremendous growth over the last three decades, and in the last five years, its application has widened significantly. Three-dimensional printing technology has the potential to fill the gaps left by the limitations of the current manufacturing technologies, and it has further become exciting with the addition of a time dimension giving rise to the concept of four-dimensional (4D) printing, which essentially means that the structures created by 4D printing undergo a transformation over time under the influence of internal or external stimuli. The created objects are able to adapt to changing environmental variables such as moisture, temperature, light, pH value, etc. Since their introduction, 3D and 4D printing technologies have extensively been used in the healthcare, aerospace, construction, and fashion industries. Although 3D printing has a highly promising future, there are still a number of challenges that must be solved before the technology can advance. In this paper, we reviewed the recent advances in 3D and 4D printing technologies, the available and potential materials for use, and their current and potential future applications. The current and potential role of 3D printing in the imperative fight against COVID-19 is also discussed. Moreover, the major challenges and developments in overcoming those challenges are addressed. This document provides a cutting-edge review of the materials, applications, and challenges in 3D and 4D printing technologies.

“…Further, its ability to recover its original shape makes it ideal for soft robotic applications [173]. Several studies have been dedicated to designing shape memory material based soft robotic grippers [174][175][176][177][178]. These grippers are extremely agile and capable of handling a large selection of objects.…”

The concept of 4D printing involves the formation of complex three-dimensional structures having the ability to adopt different shapes and forms when subjected to different environmental stimuli. Some researchers simply view this technique as an extension of 3D printing or additive manufacturing with the added constraint of time. However, the unique shape change mechanism exhibited in this process is due to a combination of shape programming and the usage of smart active materials mostly polymers. This review article highlights the various smart materials, activation mechanisms and the shape-changing techniques employed in the 4D printing process. The potential of these shape-changing structures and their current applications in various biomedical and engineering fields is also explored. The article aims to emphasize the potential and viability of 4D printing and is directed towards providing an in-depth insight into the 4D printing process.

“…Based on previous works, 13,14 we have discussed the advantages and disadvantages of the additive manufacture of soft actuators using silicon-based materials, that together with a new design perspective, targeted for a fully AM fabrication we investigate how fabrication challenges and controllability issues can be handled for the introduction of such actuators as reliable products in production processes. Due to the problems associated with fabrication and assembly of soft material actuators and robots, we focus on the development of a single fully 3D printed actuator as one element of a manipulator body.…”

“…Due to the problems associated with fabrication and assembly of soft material actuators and robots, we focus on the development of a single fully 3D printed actuator as one element of a manipulator body. Drawing from previous experiences and expertise in additive manufacture of soft materials as in, 13,14 and in comparison with typical manufactured actuators where shapes and features, due to the complexity of casting, is limited, as presented in 8 see (figure 2a), we present an innovative three axis design for a unibody soft actuator (see figure 2b). In this paper, we intend to demonstrate the possibility to fully 3D print a soft actuator, that can be later used to build a fully 3D printed soft robotic manipulator.…”

With the introduction of collaborative robots in production environments, the harm to workers by using traditional robots with rigid links is inherent. A new generation of robots made from flexible soft materials that decreases collision danger by self-deforming actions has been proposed as a promising solution for the human-robot collaboration environments. Recently, by the development of additive manufacture of elastic soft materials, new design opportunities arise for these so-called soft robots. However, robustness that is required for production environments is still not achieved. This paper presents a design approach of a fully additively manufactured three-axis soft pneumatic actuator. For its use in flexible soft robotic manipulator systems, design guidelines, a direct 3D printing process with elastic materials and a low-level PLC semi-automated pressure regulation control system are presented. To validate the proposed design, the actuator is manufactured and tested for maximum contact force, bending motion reaction and its signal response.
