CNC Rapid Prototyping is the first step to test the product feasibility. Prototype(model) is the first sample of production, the designer usually uses this method to get a prototype to observe his new product`s advantages or disadvantages to avoid wasting too much time, money and manpower between the processing of rapid prototyping. Rapid Prototyping can be applied to many fields.
