The prototype is a sample made according to the 3D drawing on the premise of no mold opening, which is used to check the appearance or structural rationality of the sample.

1.RP prototype：Refers to the 3D printing prototype, which is mainly divided into SLA and SLS.The advantages of RP prototype are mainly reflected in its rapidity .However, it is mainly formed through the stacking technology, so the RP prototype is generally relatively rough and has requirements for the wall thickness of the product. For example, if the wall thickness is too thin, it cannot be produced.

2.CNC prototype:  The prototype produced by CNC precision machining.The advantage of CNC prototype is that it can accurately reflect the information expressed in the drawings and the high surface quality of prototype. Especially after finishing the surface painting and silk-screen printing, even than the mold after the production of products even more glamorous. Therefore, CNC prototype manufacturing is becoming the mainstream of prototype manufacturing industry.
