Layered processing method for three-dimensional object data and 3D printing equipment

Abstract

The application provides a layered processing method for three-dimensional object data, a layered processing system, a 3D printing method, a 3D printing device, a computer device, and a computer-readable storage medium; The attribute of the color appearance of the degree, for the object that needs a certain degree of distinction in appearance, such as color and structural mutation (or step) to identify the information carried by different parts, the three-dimensional attachment model is placed based on the attachment relationship in the pre-processing. The three-dimensional main body model is layered and over-cured, and at least part of the slices are over-cured according to the set rules based on the obtained slice data in the subsequent printing, and different exposure strategies are used in the printing. A three-dimensional object with identifiable assembly information or configuration information is obtained during printing, which simplifies the production process and reduces production costs.

Description

technical field [0001] The present application relates to the field of 3D printing, in particular to a layered processing method for three-dimensional object data, a layered processing system, a 3D printing method, a 3D printing device, a computer device, and a computer-readable storage medium. Background technique [0002] 3D printing is a kind of rapid prototyping technology. Specifically, it is a technology based on digital model files, using powdered metal, plastic, resin and other materials that can be bonded or cured, to construct objects by layer-by-layer printing. 3D printing equipment manufactures 3D objects by performing this type of printing technology. 3D printing equipment is widely used in molds, customized products, medical fixtures, prostheses and other fields due to its high molding precision. [0003] Among them, when manufacturing the model, it is usually printed layer by layer in the manner of layered slice processing, and the light-cured material betwee...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of this application is to provide a layered processing method, which is used to solve the pre-processing stage in the prior art and the printing products implemented according to the pre-processing measures do not have structural appearance distinguishing characteristics or distinguishing Low accuracy, for products that need to display a certain pattern and color, the structure needs to be disassembled and printed with different materials, etc.
