3D Printing, also known as additive manufacturing (AM) is an emerging technology which is expected to replace the traditional fabrication methods and manufacturing processes that involve excessive effort, expense, and time. Through 3D printers one can make a solid physical object without any need of moulds, tools or machines.
Instead of creating a sample in a factory, a self-contained printer can make objects from three-dimensional drawings designed on a computer. With this technology, successive layers of material are deposited under computer control to form an object. 3D printing technology is expanding in several directions and in the future the majority of fields will have a high scope of 3D printing applications.
