The prototype is are very important to designers，Because the quality of the prototype determines the product development progress and its customers on the first impression of the prototype samples.In fact, follow the below three basic principles can make the ideal prototype:

 

1. Restore of design drawing:  The prototype is the product to verify the design, so it doesn't need too much magnificence. The most important thing is to restore the design drawing.

2 .Moderate color: The color of prototype is too bright-colored can affect visual effect, The choice on processing color should not be too warm, also should not be too cold, moderate is a better choice. Of course, this refers to the general prototype, if it is the exhibition prototype is to depends on the situation.

3. Choose the material properties: When the prototype processing must choose the material which conforms to the product characteristic, the prototype which processes can be achieved the product design request, such as temperature resistance, anticorrosion, flame retardant and so on.
