A new and incredibly promising technology is 3-Dimensional (3D) printing, which first emerged in the 1980s and has been continuously advancing since then. It is a distinct way of layerby-layer material deposition that sets itself apart from other conventional modelling techniques through material molding and removal. Modelling by adding material, 3D printing can produce things with incredibly intricate geometries and even with previously unheard-of accuracy. It may be applied in a variety of fields, including aviation, the automobile industry, production, science, education, and medicine. Printing by adding material is a significant breakthrough for several writers in these latter domains of application. The spectrum of potential applications for 3D printing is enormous and highly promising, including modelling learning and training prototypes, producing tailored prostheses, and printing biological and functioning organs. In General, this article will be focusing on the Major applications of 3D printers in education and medicine
