Abstract: The main aim of this research work is mass production in relative less time by using the Rapid prototyping technology. In the mechanical engineering we used the rapid proto typing technology to get large amount of money easily. In the industries creating the new design is very important thing. For the new design the industries are spending more money and time for preparing the proper tool and equipments. At that time we used the rapid prototyping technology we can reduce the cost and time of the new design. The designers from various departments are a part of rapid prototyping technology. They are well experienced and well knowledge in tool developing. These designers can make design in CAD system with in less time. Some of the complex surfaces are designed by rapid prototyping technology for this study.
