In recent days 3D printing and additive manufacturing is widely used in the entireworld.3D printing is construction of a three-dimensional object from a digital 3D model and it’s creates physical objects from the geometrical representation by successive addition of materials. Additive Manufacturing technologies are developing impressive and expected to bring about the next revolution. Additive manufacturing is replacing traditional manufacturing methods in some applications is unique properties of customizability and versatility.
In the 1980’s 3D printing techniques were considered in suitable for the production of aesthetic prototype. It can be increase to the printing process is considered on industrial production technology, additive manufacturing can be used synonymously with 3D printing. 3D printer prints the ability to produce complex shapes that would be otherwise impossible to construct by hand, including parts with internal truss structures to reduce weight. Fused deposition modeling (FDM) used to continuous filament of a thermoplastic material. 3D Printing applications are  Automobiles, Nanotechnology, Aerospace, Model making, Prosthetics, Construction, Medical Field (Audiology, Dentistry, Prosthetics, Surgery, 3D Printed Organs), Art (Movies and visual effects, Art restoration), Research.
