In the 3D printers available in the market these days, generation of output takes place from programs of mapping which support 3D modeling programs or 3D CAD programs. Some companies have their own soft wares for PLY, VRML, and STK formats to allow 3D viewing, scaling and labeling of text, and fine-tuning preceding printing.
Working: All the 3D printers’ posses five basic process functions for creating a three-dimensional model.

The term Rapid Tooling (RT) is used to describe a process which either uses a Rapid Prototyping (RP) technique as a medium to create a mold quickly or uses the Rapid Prototyping process directly to fabricate a tool for a limited volume of prototypes. RT takes less tooling time and cost than a conventional tool. It can be used to make multiple parts out of alternative materials. The rapid tooling processes include the following:
* Composite Injection
* Kirksite Injection
* Silicone Vacuum Cast
* Zinc and Aluminum Plaster Cast
* Spray Metal Injection
* Sand Cast

Rapid prototyping (RP) and rapid tooling (RT) technologies, processes and developments have changed over the years, but there is one thing that has remained constant: the challenge to get functional prototypes and a method to obtain low-volume production parts fast, without breaking the bank.
The race in rapid tooling to get either functional prototypes or low-volume production parts has created many methods of rapid tooling, which have worked well and not so well. The downside to each of these methods has been the consistency and the lack of broad use from application to application.
