Embodiment 1

[0019] A multi-part rapid printing method based on additive manufacturing, the method includes the following steps:

[0020] 1) Slice the 3D physical models of multiple parts to be printed to obtain the total cross-sectional layer and its plane data of each model;

[0021] 2) According to the total cross-section layers of each model, the computer control system controls the arrangement of each model on the working platform, so that the one with the largest total cross-section layers is placed in the middle, and other models are sequentially decreased according to the total cross-section layers along the moving direction of the scraper Sequentially arranged on both sides of the total cross-sectional layer;

[0022] 3) According to the plane data of each section layer of each model, the current layer plane data and the current layer contour data of each model are obtained;

[0023] 4) According to the contour data of the current layer of each model, control the scraping device ...

Abstract

The invention discloses a multi-part rapid printing method based on additive manufacturing. The method first slices and layers the 3D models of each part, and obtains the total section layers of each model and its plane data; The number of layers, the computer control system controls the arrangement of each model on the workbench, so that the one with the largest total cross-section layer is placed in the middle, and other models are arranged in the descending order of the total cross-section layer along the moving direction of the scraper. Then, according to the plane data of each model, the molding system controls the movement of the scraper so that the scraper reaches the edge of the maximum two models along the direction of the scraper movement, and so on, and finally completes the rapid printing of all parts. The invention not only realizes the intelligent sorting of multiple parts, reduces the moving distance of the scraper, and improves the work efficiency, but also realizes the rapid and automatic identification and positioning of the edge positions of multiple parts, and can accurately locate the position of the paving device.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a multi-part rapid printing method based on additive manufacturing. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, realizes the printing of three-dimensional models through the process of automatic numerical control layer-by-layer material accumulation. Compared with traditional processing technology, 3D printing technology does not need to make additional molds, and can directly process finished products. Moreover, it can overcome the special structural obstacles that cannot be realized by traditional machining, can realize the simplified production of any complex structural parts, and can automatically, directly and accurately transform design ideas from CAD models into models or devices with certain functions. [0003] At present, 3D printing technology can be divided into: fused deposition technology FDM,...
