4d shapes make9/12/2023 The congruent printing of different materials will form material anisotropy, which enables the object to change the structure by bending, elongating, twisting, and corrugating along its axes. The meta-material structure is generated by combining different materials that provide superimposed structural responses when activated by external stimuli. Researchers are currently looking ahead of conventional 3D printing, which fabricates structures from a single material, to develop a meta-material structure. The increasing need for flexible objects in various applications, such as self-folding packaging, adaptive wind turbines, etc., has fueled the emergence of 4D printing. Despite its ability to create complex, bio-inspired, multi-material designs, 3D printing is not yet ready to be adopted in large-scale manufacturing. 3D printing technology has witnessed continuous advancements over the last 3 decades and has evolved drastically. 3D printing enables manufacturers and researchers to develop complex shapes and structures, which were earlier considered impossible with traditional fabrication methods. It has completely transformed the way parts/components and equipment are manufactured in the industry, along with their design and development. Emergence of 4D Printing from 3D PrintingģD printing, an additive manufacturing technique, is considered as one of the most disruptive innovations in the field of modern manufacturing. This shape-changing phenomenon of 3D printed objects is based on the material’s ability to transform over time in response to specific stimuli, and it does not require human intervention to aid the process. By integrating the dimension of time, printed objects change their shape dynamically based on the needs and demands of the situation, without any electromechanical parts or moving parts. With this new dimension, 3D printed objects possess the capability to change its shape by itself over the influence of external stimuli, such as light, heat, electricity, magnetic field, etc. The introduction of the fourth dimension to the 3D printing technology is termed as “4D Printing”.
