Rapid prototyping or Rapid prototyping manufacturing, In the automotive industry, it is called RP prototype.

Rapid prototyping technology is developed on the basis of modern CAD/CAM technology, laser technology, computer numerical control technology, precision servo drive technology and new material technology. Different kinds of rapid prototyping systems have different forming principles and system characteristics because of different forming materials. However, the basic principle is the same, that is, "layered manufacturing, layer by layer superposition", similar to the mathematical integration process. 


It can directly accept the data of product design (CAD) without preparing any mould, cutter and fixture, and quickly produce samples, dies or models of new products. Therefore, the popularization and application of RP technology can greatly shorten the development cycle of new products, reduce the development cost and improve the development quality. From the traditional "removal method" to today's "growth method", from molded manufacturing to non-molded manufacturing, this is the revolutionary significance of RP technology to manufacturing industry.


(1) The rapidity of the whole forming process is suitable for the fierce modern market;

(2) Three-dimensional solid with arbitrary complex shape can be manufactured.

(3) Driven directly by the CAD model, the design and manufacturing are highly integrated. Its intuition and easy modification provide a good design environment for the perfect design of products.

(4) No special fixtures, dies and cutting tools are needed in the forming process, which not only saves the cost, but also shortens the manufacturing cycle.

the highly integrated technology is not only the inevitable product of the development of modern science and technology, but also the comprehensive application of them, with distinct high-tech characteristics.

The above characteristics determine that Rapid prototyping technology is mainly suitable for new product development, rapid single and small batch manufacturing, complex shape parts manufacturing, die and model design and manufacturing, also suitable for difficult-to-process materials manufacturing, shape design inspection, assembly inspection and rapid reverse engineering.
