Although many developments have been made, limitations are still very much in existence, particularly with regards to function and application. The objective of this short review is to discuss the developments, challenges and outlook for 4D printing technology. The review revealed that The use of computing, 3D solid modelling applications, layering materials and machine equipment is common to majority of additive manufacturing technologies. The 3D printing technology is a well-known technology across the world and this is one of the most rapidly growing technology. This technology certainly offers us a great advances in many different fields in our life. Medicine, industrial buildings, education and the automotive sectors are just some of the areas where 3D printing technology promises a revolution. This paper presents a comprehensive study of the 4D printing technology and includes the practical concepts, the materials used a with a focus towards it applications in industry sector. Also, in this paper, the immediate future expectations of 4D printing technology were listed. In a variety of industries, Additive Manufacturing has revolutionized the whole design—fabrication cycle. Traditional 3D printing is typically employed to produce static components, which are not able to fulfill dynamic structural requirements and are inappropriate for applications such as soft grippers, self-assembly systems, and smart actuators. It processes smart materials by using 3D printing for fabricating smart structures that can be reconfigured by applying different inputs, such as heat, humidity, magnetism, electricity, light, etc. At present, 4D printing is still a growing technology, and it presents numerous challenges regarding materials, design, simulation, fabrication processes, applied strategies, and reversibility. In this work a critical review of 4D printing technologies, materials, and applications Tumbir Motorlu Amcık Lar provided. D Printing has been recognized as a disruptive technology for future advanced manufacturing system. With a great potential to change everything from our daily lives to the global economy, significant advances in 3D printing technology have been made with respect to materials, printers and processes. In this context ,although similar to 3D Printing technology,4D printing technology adds the fourth dimension of time. The basic principle of 4D printing with multi material structure is to create precisely controlled localized internal stress with in a printed construct, which upon subsequent stress release can undergo further 3D shape shifting in a predictable manner Tumbir Motorlu Amcık Lar this review, we look into the main factors composing 4D printing technology such as smart materials and design. Finally we summarize the current and future applications of 4D printing. 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 AMhas 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. Significant advances in computer aided design, additive manufacturing and materials science Tumbir Motorlu Amcık Lar opened up the possibilities of self-assembly systems, self-healing and material property alterations. Printing layer by layer allows complex geometries to be built, previously difficult under conventional manufacturing routes. This paper is a review of the current materials available for 3D printing, enabling the emergence of 4D printing, a 'smart material' that responds in a programmed way to an external stimuli. The outlook is towards potential space applications, in all areas including deployable structures, antennas and medical supplies. The advancement in 3D printing has led to the rapid growth of 4D printing technology. Adding time, as the fourth dimension, this technology ushered the potential of a massive evolution in fields of biomedical technologies, space applications, deployable structures, manufacturing industries, and so forth. This technology performs ingenious design, using smart materials to create advanced forms of the 3-D printed specimen. Improvements in Computer-aided design, additive manufacturing process, and material science engineering have ultimately favored the growth of 4-D printing innovation and revealed an effective method to gather complex 3-D structures. Contrast to all these developments, novel material is still a challenging sector. However, this short review illustrates the basic of 4D printing, summarizes the stimuli responsive materials properties, which have prominent role in the field of 4D technology.
