Rapidly 4D printing has made tremendous growth in diverse fields such as healthcare, aerospace, manufacturing industry, and advanced manufacturing systems. This technology is found to have a greater potential while considering the daily applications and the economy. Besides this 4D printing allows the conversion of a 3D printed structure to perform some interaction mechanisms by changing the functions based on the response time to parameters such as temperature, pressure, water, and light and so on. Also 4D printing is function of time, printer independent targets shape and functionality. Therefore, this paper conducted an exhaustive review of the recent researches in materials and designs leading to its use in a 4D printing process. This review also incorporates a detailed survey of smart material and multi-materials used to change the function and shape of those materials after printing. An attempt has been made in this paper to cover a more conclusive review in deciding the best appropriate material that may well be utilized in 4D printing process.
