What is Additive Manufacturing?

Additive manufacturing refers to a process by which digital 3D design data is used to build up a component in layers by depositing material. The term "3D Printing" is increasingly used as a synonym for Additive Manufacturing. However, the later is more accurate in that it describes a professional production technique which is clearly distinguished from conventional methods of material removal.

Additive vs Subtractive ManufacturingIn subtractive manufacturing we start with stock and remove material to get the net shape (traditional machining).In additive manufacturing we start with nothing and add material to get the net shape.
In additive manufacturing, 3D objects are built by adding material in layer upon layer fashion. Materials ranging from plastics, thermoplastics, ceramics, biochemicals, metals, and concrete can be used for production in this sector. Even work is under process to develop human tissues using additive manufacturing techniques.
