Application in appearance and man-machine evaluation
In the design stage of new product development, although the design drawings and computer simulation can be used, the prototype cannot be displayed, and it is often difficult to make correct and rapid evaluation. The designer can achieve the purpose of inspection by making prototype models. The traditional model production mainly adopts the hand-made method, and the production process is complex. The hand-made prototype model not only has a long construction period, but also is difficult to achieve the precise size required by the appearance and structure design, so its function of checking the rationality of the appearance and human-machine design is greatly discounted.
Compared with the traditional manual model, the high-precision and high-quality prototype made by Shandong rapid prototyping equipment can more intuitively reflect the designer's creativity in the form of physical objects, facilitating the product's appearance modeling and human-machine characteristics evaluation.
The molding parts obtained by the current rapid prototyping process are all single color, and the color is mainly determined by the material. In order to evaluate the color appearance of the product, it is sometimes necessary to paint manually. With the development of color molding technology, this problem can be solved. Human-machine evaluation mainly includes the size of molded parts and the ease of operation, and rapid prototyping can well meet this requirement.
Application in product structure evaluation
The prototype made by rapid prototyping can be assembled as the actual product, so it can directly reflect whether the structural design is reasonable or not, and the ease of installation, so that the structural engineer can find and solve problems as soon as possible. Due to the high cost of mold manufacturing, relatively large molds are often worth hundreds of thousands or even millions. If the structure is unreasonable or other problems are found after the mold is opened, the loss can be imagined. The prototype manufacturing using rapid prototyping technology can solve the problem before opening the mold, which greatly improves the efficiency of product development.
Combined with reverse engineering
Reverse Engineering (RE), also known as reverse engineering, is to measure the real object or model with certain measuring means, and then reconstruct the CAD digital model of the real object through 3D geometric modeling method according to the measured data, thus realizing the product design and manufacturing process. For most products, their 3D models can be designed on the general 3D CAD software. However, due to the consideration of some factors, such as function, technology, appearance, etc., the shape of some parts is very complex, and it is difficult to design their solid models on the CAD software. In this case, the 3D solid models can be obtained through model measurement and data processing.
As an important means of developing new products and digesting and absorbing advanced technologies, reverse engineering and rapid prototyping technology can meet the requirements of digesting foreign technological achievements. For the existing solid model, you can first obtain the 3D entity of the model through reverse engineering. After processing the 3D model, you can use rapid prototyping technology to realize the rapid replication of the product, shorten the product development cycle, and greatly improve the product development efficiency.
Rapid prototyping technology can greatly shorten the product development cycle, meet the personalized and diversified needs of products, and is widely used in industrial design. However, the manufacturing accuracy, strength and durability of this technology can not meet the actual needs of the project, and the high cost of equipment operation and manufacturing, to some extent, restricts the general promotion of RP technology.
