The concept of 4D printing represents the emerging direction of manufacturing, and it is also the paradigm of fusion of existing technology and innovation. Many countries with a renewed interest in manufacturing have high expectations for technological innovation and fusion. In particular, since the global coronavirus disease epidemic is gradually under control in 2022, the importance of the real economy has been reawakened, and the development trend and competitive landscape of the manufacturing industry are faced significant changes. The manufacturing industry is the driving force for the growth, structural change, and acceleration of the economy, which exerts far-reaching and extensive influence on the national economy.

Researchers can use it to understand current research gaps and best practice pathways. The purpose of this paper was to provide a systematic, comprehensive, dynamic, quantitative, and objective analysis of the 4D printing research field in order to deepen and refine research in the field, as well as to reveal the overall existing knowledge structure and potential emerging trends. This paper constructs a visualizing technology identification framework for the global 4D printing research field for manufacturing regarding basic information, technology evolution paths, knowledge structures, and emerging trends through bibliometric techniques and Gephi and CiteSpace software. It is susceptible to subjective thinking and knowledge blindness, making it difficult to reflect the current state of research in 4D printing in a comprehensive manner. In a summary and overview of the current state of research and trends, existing studies are generally manually reviewed and organized. As a young field, it is full of new elements to be researched. * e-mail: emergence of additive manufacturing technology opens up avenues for developing manufacturing industries, and a clear future direction for additive manufacturing is 4D printing. School of Automation, Beijing University of Posts and Telecommunications, Beijing, China Therefore, in this chapter, the most relevant materials that have been reported for mechanical augmentation of 3D-printed scaffolds are reviewed.Wencai Zhang 1, Zhenghao Ge 1 and Duanling Li 1 ,2 *Ĭollege of Mechanical and Electrical Engineering, Shaanxi University of Science & Technology, Xi'an, China Various inorganic materials were reported, including metal composites, metal oxides, and ceramic materials. Different sources were reviewed in this chapter involving 3D structures for industrial applications and 3D-printed scaffolds for biomedical applications. The overall aim is to provide a relatively exhaustive account of the various inorganic materials applied for 3D printing innovation. Particularly, the utilization of inorganic materials to reinforce 3D-printed scaffolds as reported in the current literature is highlighted. The current chapter focuses on potential techniques that are applicable for the augmentation of mechanical properties of 3D-printed scaffolds. Several methods have been utilized to augment the mechanical properties of the 3D-printed scaffolds. Mechanical properties of three-dimensional (3D) scaffolds are critical for their biomedical applications. We determined our review by aiming our future directions such as the "dream it and make it feasible" technology. Finally, we explored the future application potential under succeeding context: SMA-based knitted garments, transforming food, and relevant sectors wise development and proceedings with the advancement in smart materials. Furthermore, the capabilities of single and multiple materials mechanisms for shape-shifting behavior are summarized. Starting from a generalized idea, and fundamental workflow, together with a graphical manifestation of the 4D printing concept, and 4D printing for shape-memory materials (SMMs), self-fitting wearables based on shape memory alloys (SMAs) are reviewed exclusively. Herein, the proposed review article discusses material arrangements for 4D printing, highlighting the structural evolvement mechanism, the behavior of deformation, and their prospective implementation with respect. Although significant progress on smart material performance has been made and different studies have focused on new strategies and process improvements in typical additive manufacturing. 4D printing is inspired by embedded product designs to produce stimuli-responsive consumables fabricated by available commercial 3D printers.
