According to the method of manufacturing, prototypes can be divided into manual prototypes and numerical control prototypes. 

Manual prototypes: the main work is made by manual, such as ABS and greasy filth prototypes. 

Numerical control prototypes: the main work is made by numerical control latch.  It can be divided into Laser forming, CNC and 3D Printing. 

Rapidity is the main advantages of RP prototypes, but it is formed by stacking. Therefore, RP prototypes are relatively rough. This technology has requirements of wall thickness, the wall thickness is too thin to produce. 

The advantages of CNC prototypes are that it can accurately reflect the information expressed in the drawings, and the surface quality of CNC prototypes is high, especially after the surface spraying and screen printing are completed, even the products produced after the mold is opened are more glorious. Therefore, CNC prototypes manufacturing has increasingly become the mainstream of prototypes manufacturing.

Prototypes can be divided into plastic, silicone and metal according to the material. 

1.Plastic prototypes: the raw material is plastic, such as TV, displayer, mobile phone. 

2.Silicone prototypes: the raw material is silicone. The main function is to show that appearance of prototypes, like auto car, phone, toys, artist-tool and daily products. 
3.Metal prototypes: the raw material is aluminum alloy. The products are high quality, such as laptops, MP3 players, CD players, etc.

Above are the classification of prototypes. Then have you know the prototypes totally? Do you have any questions? Feel free to contact us at enquiry@nice-rapidtooling.com!
