With the development of automobile industry, the research and development cycle of automobile body products is getting shorter and shorter than before. At the same time, the requirements for product quality and ap?pearance design level are also getting higher. How to design a new model of the automobile body becomes one of the key issues in the auto industry development. A new type of automobile body CAD model was designed by using Pro ENGINEER software. Then the quality of molding surfaces was evaluated and analyzed and the molding surface that has problem was revised. The rapid prototyping of the automobile body model was manufactured by choosing and setting reasonable process parameters, and using the melted extrusion modeling ( MEM) prototyping machine, the design and development of a new type of automobile body product are realized conveniently and quickly, which shortens the research and development cycle.
