Shape-memory materials (SMMs) combined with 3D printing to develop dynamic and adaptive products which are responsive to physical, chemical, or biological stimuli. These structures are categorized into 4D-printed (4DPed) products which change their shape and properties over time dimension. 4D printing, a novel, multidisciplinary, and futuristic technology is expanding its utilization in different applications including healthcare, space, textile, soft robotics, defence, sports, aerospace, and automotive sectors. This review article focuses on the recent and insightful developments in the 4DP technology of SMMs especially shape-memory polymers. This review also integrates printing technologies, the programming of materials for specific actuating mechanisms, and the most recent applications of 4DPed structures/products. Future perspectives and countless opportunities of this 4DP technology are outlined to address the current challenges which will help evolve and promote this novel technology as the mainstream manufacturing approach for developing real-world products in a myriad of engineering sectors. 4DP technology progresses beyond imagination, since its inception and will promote technological and manufacturing renaissance in the material science field. This technology will profoundly impact manufacturing and daily human life in the future.

“…In recent years, multimaterial direct ink printing (4D direct ink printing) which employs an extra time dimension has emerged as a fast and straightforward technique to generate various hydrogel robots. Simińska-Stanny et al (2022) developed a graded and patterned 4D-printed magnetic hydrogels showing spatially anisotropic response to magnetic fields. Before printing, the magnetic inks were subjected to the magnetic field, resulting in the arrangement of incorporated magnetic nanoparticles.…”

Magnetic hydrogels composed of hydrogel matrices and magnetic nanomaterials have attracted widespread interests. Thereinto, magnetic hydrogels with ordered structure possessing enhanced functionalities and unique architectures, show tremendous advantages in biomedical fields. The ordered structure brought unique anisotropic properties and excellent physical properties. Furthermore, the anisotropic properties of magnetic ordered hydrogels are more analogous to biological tissues in morphology and mechanical property, showing better biocompatibility and bioinducibility. Thus, we aim to systematically describe the latest advances of magnetic hydrogels with ordered structure. Firstly, this review introduced the synthetic methods of magnetic hydrogels focus on constructing ordered structure. Then, their functionalities and biomedical applications are also summarized. Finally, the current challenges and a compelling perspective outlook of magnetic ordered hydrogel are present.

“…4D printing is defined by using smart materials, also known as stimuli-responsive materials, to fabricate implants by applying 3D printing and bioprinting technologies ( Figure 1 ) ( Simińska-Stanny et al, 2022 ). Therefore, the 4D printed device is similar to the 3D printed one while the fourth dimension, the time, allows the smart material to become dynamic and to transform upon a stimulus.…”

Smart materials are able to react to different stimuli and adapt their shape to the environment. Although the development of 3D printing technology increased the reproducibility and accuracy of scaffold fabrication, 3D printed scaffolds can still be further improved to resemble the native anatomy. 4D printing is an innovative fabrication approach combining 3D printing and smart materials, also known as stimuli-responsive materials. Especially for cardiovascular implants, 4D printing can promisingly create programmable, adaptable prostheses, which facilitates implantation and/or create the topology of the target tissue post implantation. In this review, the principles of 4D printing with a focus on the applied stimuli are explained and the underlying 3D printing technologies are presented. Then, according to the type of stimulus, recent applications of 4D printing in constructing smart cardiovascular implants and future perspectives are discussed.
