3D printing is a form of additive manufacturing technology where a three dimensional object is created by successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that closely emulate the look, feel and functionality of product prototypes.

In recent years 3D printers have become financially accessible to small and medium sized business, thereby taking prototyping out of the heavy industry and into the office environment. It is now also possible to simultaneously deposit different types of materials.

While rapid prototyping dominates current uses, 3D printers offer tremendous potential for production applications as well.[1] The technology also finds use in the jewellery, footwear, industrial design, architecture, automotive, aerospace, dental and medical industries.
