Layering processing method of three-dimensional object data and 3D printing device

Abstract

The invention provides a layering processing method and system of a three-dimensional object data, a 3D printing method and device, a computer device and a computer readable storage medium. Through using the characteristic that a material to be cured can display color appearance with the distinction degree after over-curing, a certain distinction degree such as color and structure sudden change (or the step) is needed in the appearance to recognize the object with the different portions carrying information, in the pretreatment, on the basis of the relations of dependence, the three-dimensional attachment model and the three-dimensional main model are mounted, and are subjected to layering processing, an over-curing property is arranged, in the subsequent printing process, on the basis ofthe obtained slicing data, at least one part is sliced to carry out over-curing with the set rule, in the printing process, different exposure strategies are adopted, in one-time printing, the three-dimensional object with recognized assembling information or configuration information is obtained, the production process is simplified, and the production cost is reduced.

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.
