Development of casting pattern by using rapid prototyping

The competition in the world market for manufactured products has intensified tremendously in recent years. It has become important to produce the product fast to reach the market as early as possible, by using the available new technology.In order to improve the quality in foundries the CAD/CAM and other advanced manufacturing techniques have been used as a tool to achieve quality and productivity. In this concern, the use of Rapid Prototyping (RP) is not yet fully practiced in foundries. This project work provides an initial study on the fabrication of a master pattern (step bar) of casting using rapid prototyping technique as well as presenting its scope and benefits compared to the current practices.
