3D printing additive manufacturing method of kettle-shaped thin-wall part

Abstract

The invention provides a 3D printing additive manufacturing method of a kettle-shaped thin-wall part. The 3D printing additive manufacturing method of the kettle-shaped thin-wall part comprises the following steps of modeling, specifically, through three-dimensional modeling software, a solid three-dimensional model is established to enable an opening of the kettle-shaped thin-wall part to face upwards; cutting, specifically, through three-dimensional design software, cutting treatment is performed on the solid three-dimensional model to obtain cutting characteristic data; slicing, specifically, through the three-dimensional design software, the cutting characteristic data are spliced in the Z-axis direction to obtain section contour data; filling, specifically, through filling software and the section contour data, path filling is performed on a printing area to obtain laser processing parameters and generate processing information; and scanning and processing, specifically, the kettle-shaped thin-wall part is obtained by printing through the processing information. The 3D printing additive manufacturing method of the kettle-shaped thin-wall part can be used for 3D printing of a thin-wall kettle body with a complex structure, the 3D printing efficiency is improved, the number of supporting structures in the 3D printing is reduced, the generated material waste is reduced, and the later processing work is reduced.

[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
