[Abstract]:With the rapid development of computer technology, the method of product design has been further improved, the period of product renewal has been shortened greatly, and the speed of product development has become the key to the market competition of products. Traditional machining methods exist in the process of physical model, slow speed, high cost, but also in the forming accuracy and dimensional accuracy and other deficiencies, complex modeling design products can not even be processed and manufactured. This not only reduces the speed of product design and development at the same time the cost of the corresponding high. The rapid prototyping process can quickly and accurately produce complex modeling models and parts, and make up for the shortcomings of traditional methods. It has the advantages of wide range of molding materials, low cost, small volume, no pollution and so on. It has a good prospect in the future rapid prototyping field. It provides a reliable tool for the simulation of product design prototype and speeds up the step of product development and put into the market, but there are still some problems of relatively low molding quality. Tourism product design is a process of combining technology and art because of its rich design content and high requirement of product market speed. Therefore, it is necessary to make it conform to the laws of science and technology. The application of rapid prototyping technology can meet the requirements of the market speed of the products by giving full play to their material functions and the aesthetic expression of their forms. This paper mainly adopts the literature method, the experiment method, the detection and analysis research method. Firstly, aiming at the main defect of the low quality of melt deposition (FDM) forming technology, the paper puts forward a scheme to improve the surface quality of molten deposition forming parts, taking the design and manufacture process of tourism products as the turning point. A method for improving the precision of forming parts and reducing the surface roughness of forming parts is obtained. Then, based on rapid prototyping technology, the research of square structure, cylindrical structure, circular structure, triangle structure, shell structure, frame structure and complex polygon structure in tourism products is carried out. The rules and main error solutions of various shapes and structures in the process of forming are obtained. Then, the post-processing method, the effect of rapid prototyping and the role of rapid prototyping in improving tourism products are discussed and studied. Finally, the research and design of two tourism products and the molding experiment are used to verify the method of how to improve the design efficiency of rapid prototyping technology in tourism product design. It is found that the generation of the FDM step error is mainly determined by the delamination thickness of the model, the angle between the normal vector on the surface of the molded part and the machining plane, and the size of the molded part. The error between normal vector direction and stacking plane on the surface of the model increases rapidly in the range of 0 ~ 60, the increasing trend of the step error between 60 and 90 tends to be gentle, and when 偽 is close to 90, the error almost does not increase. The influence of step effect on the surface quality of parts can be effectively reduced by optimizing the selection of delamination thickness and machining direction. Rapid prototyping technology in the process of tourism product design, according to the design drawings can be made by the physical model can intuitively and fully express the design ideas, functional testing, man-machine analysis, structural assembly inspection and prototype production test sales, etc. Compared with the traditional model processing method, the speed of 40% can be increased by 65%, and the cost of materials can be saved by about 75%. The surface quality of the molded parts can be improved by 20% and 40% respectively. The application of rapid prototyping technology can also promote the rapid realization of design inspiration, change the traditional design procedures and methods of tourism products, and improve the speed and efficiency of product development.
