Using rapid prototyping method can simply and quickly set up prototypes required, mainly plastics (PS, PENNSYLVANIA, ABS, etc.) prototype. Development of fresh products it has a very important role. Through that prototype, designers can quickly evaluate the reasonableness in the design, feasibility, and to fully express its ideas, evaluate and alter the design in an exceedingly short period of your energy to complete. Therefore, it can significantly shorten the product development cycle in addition to reduce development fees. Specifically, it mainly has the examples below three purposes.

(1) Examine the exterior design
Many products, especially household appliances, mobile communication gear and automotive appearance in the beauty and novelty in the requirements is high. Traditional test method should be to shape the product with all the CAD graphic display on the computer screen, but this technique intuitive real awful. By rapid prototyping method in an exceedingly short period of your energy, to make direct by using low cost design model for developers and users to review, modify the structure and then screened, until satisfied.

(2) Perform tests
Designers can quickly prototype using that RP function exams, such as stream analysis, stress investigation, aerodynamics analysis, to view whether best meet the requirements of the design to optimize product design. Such since fans, air drum, for example. The design, obtain best blade surface, the minimum noises structure.

(3) Disturbance detection assembly
The introduction of new products, especially in the limited space in the complex system, the assembly regarding interference detection is important. SLS prototype parts may be used to make the assembly simulation to observe whether the coordination between the many components and the way to influence each additional. Through this test might be successful in that shortest time to perform the design.
