A 3D printing additive manufacturing method for pot-shaped thin-walled parts

Abstract

The invention provides a 3D printing additive manufacturing method of a pot-shaped thin-walled part, said method comprising the following steps: modeling, using three-dimensional modeling software, making the opening of the pot-shaped thin-walled part upward to establish a solid three-dimensional model; cutting , use the 3D design software to cut the solid 3D model to obtain the cutting feature data; slice, use the 3D design software to slice the cutting feature data in the Z-axis direction, and obtain the cross-sectional profile data; fill, use the filling software and the cross-sectional profile data , path filling is performed on the printing area, laser processing parameters are obtained, and processing information is generated; scanning processing, through processing information, is printed to obtain a pot-shaped thin-walled part. The present invention can be used for 3D printing of thin-walled jugs with complex structures, improves the efficiency of 3D printing, and reduces the number of support structures in 3D printing, thereby reducing material waste and post-processing work.

[0002] With the rapid development of science and technology, the market has higher and higher requirements for the structure, performance, precision, production efficiency and product types of the parts processing industry, and there is an obvious trend of customization in the parts processing industry. The proportion of demand is increasing, and the traditional mechanical processing cannot meet the individualized product needs of the demand side. In order to meet the market demand and ensure the smooth transformation of enterprises, more and more parts processing enterprises are currently targeting the direction of research and development in additive manufacturing. Technology, that is, 3D printing technology, the use of 3D printing technology can effectively meet the high-quality, high-efficiency, multi-variety, and small-batch production methods required by the current market. For example, in the traditional production of pot-shaped thin-walled parts, stamping or sheet metal parts are generally used. Metal and welding are used to manufacture, but the above method cannot effectively manufacture pot-shaped thin-walled parts with special structures, and can only complete the manufacture of simple shapes, and in the manufacture of metal pot-shaped thin-walled parts, it will inevitably The phenomenon of material springback causes deviations in the size of the manufactured parts, which is time-consuming and laborious and is not conducive to the normal development of the parts processing industry. The use of 3D printing technology can effectively overcome the above problems
