Tissue engineering is a technique for creating functioning tissue for regenerative and drug screening. Recently, engineering, chemistry, biology, computer science, and biomaterials are among the fields where three-dimensional (3D) and four-dimensional (4D) printing have developed as the next iteration of manufacturing techniques.Through the layer-by-layer inclusion of various materials, 3D printmaking allows for the production of complicated structures with higher precision. Intelligent materials that alter size/color, emit an electrical current is biologically active, or achieve an objective in subjected to environmental stimuli pave the path for creation of dynamical 3D assembliescalled 4D printing.3D and 4D printing methods have a lot of possible for making scaffolds for tissue engineering, particularly for making patient-specific structures. These technologies can also be used to print physiochemical guide signals to enhance the level and speed of focused tissue repair. This analysis provides a thorough examination of 3D to 4D printing, as well as the advantages of using them in tissue regeneration over alternative scaffolding techniques. Moreover, theon-going evolution from 3D to 4D print was emphasized with prominence on the innovative uses in the medicinal arena.
