“…Recent advancements in multimaterial three-dimensional (3D) printing technologies have significantly improved our capability to fabricate complicated 3D structures with intricate details through micron-scale placement of various materials with different properties. In particular, multimaterial inkjet 3D printing provides high design freedom to produce complex composite structures by selectively depositing photopolymer droplets on a build tray followed by UV illumination to trigger photopolymerization, which transforms the droplets of various constituents and compositions into solids with different mechanical properties [19][20][21][22][23][24][25][26]. Using this technology, the spatial arrangement of different materials over multiple length scales can be easily achieved in a single printing job, and the desired stiffness variation can be realized [27][28][29].…”

Shape memory alloys (SMAs) have been widely used to fabricate soft actuators by embedding SMA wires into various soft matrices manufactured by conventional moulding methods or novel threedimensional (3D) printing techniques. However, soft matrices of SMA based actuators are typically fabricated from only one or two different materials. Here, we exploit the great manufacturing flexibility of multimaterial 3D printing to fabricate various bending, twisting and extensional actuators by precisely controlling the spatial arrangements of different printing materials with different stiffnesses. In order to achieve a broad range of deformations, ten different printing materials were characterized and used in the actuators design. In addition, we developed a finite element model to simulate complex deformations of the printed actuators and facilitate the design process. The model incorporates a user defined material subroutine that describes the nonlinear temperature dependant behavior of SMAs. The results show the efficiency and flexibility of multimaterial 3D printing in tailoring the deformed shape of the SMA based soft actuators, which cannot be accomplished using conventional manufacturing methods such as moulding.

“…Hence, one recommended solution to these issues faced would be to utilise the SLM process to produce the NiTi structures [5, 7, 16, 17, 19-21, 24, 25, 28, 31, 33-40]. This new method of fabricating NiTi components is sometimes referred as 4D printing [41][42][43][44].…”

“…Therefore, a better proposed solution to the problems of conventional processes and the poor manufacturability of NiTi is to utilise additive manufacturing (AM) or 3D printing techniques such as Selective Laser Melting (SLM) to fabricate NiTi components through the melting and solidification of NiTi powder [5, 7, 16, 17, 19-21, 24, 25, 28, 31, 33-40]. This new method of manufacturing NiTi SMA by 3D printing is also known as 4D printing [41][42][43][44]. The difference between 3D printing and 4D printing is that the objects fabricated in 4D printing are not static.…”
