3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
3D printing is used by architects, schools, colleges, medical and offices for creating several diagrams and plans. This technology is very much helpful for easy understanding.
