In the stage of product conceptual design, the design team is often only with the help of 2D plane drawings more abstract as visual media designed to alert scheme is discussed, concept of grass mold handmade can compensate for the plane media intuitive deficiencies to some extent mountain, but the design is expected in the precision, texture, etc. and the concept of sensitive have large deviation. The above condition in effect limits the effective exchange of product concept between teams, the application of 3D print can be accurate concept model, difference and the good and bad structure, shape and function comparison between them, so as to decide what product concept worth continuing conceptual model 3D print made can clearly reflect the existence of product concept the problem, and then modify the design, repeat the iterative process until the product concept design, perfect location.
        Because the former mode of production constraints, the designer to put their ideas into actual products must be cooperation with the manufacturers, to pay high production costs at the same time, also must always prevented due to the exchange of information caused by poor product quality flaw, thus wasting a large amount of time that could be used for the creation and experience. Because the production of final goods and small batch products to mass production mode of higher prices, thus affecting the product promotion and brand, 3D printing technology for the future allows designer to create its own design, and then through the traditional channel or network platform for sales, designers can fully carry out production according to orders, to achieve zero inventory, avoid business risk.
