Color 3D printing method and device and terminal equipment

Abstract

The invention provides a color 3D printing method and device and terminal equipment. The printing method comprises the steps of obtaining a three-dimensional original model of a to-be-printed object;conducting shell extraction treatment on the three-dimensional original model, so that an internal model and an external model of the three-dimensional original model are generated; conducting slicingtreatment on the internal model and the external model, so that multiple printing data which are in one-to-one correspondence with all printing layers are generated, wherein the printing data comprise first image information used for representing structural data, on the printing layers, of the internal model, second image information used for representing color data, on the printing layers, of the external model and third image information used for representing structural data, on the printing layers, of the external model; and printing the to-be-printed object according to the printing data.By means of the printing method, background colors in a slicing image and surface colors of the three-dimensional original model can be differentiated, and the printing failure or wrong printing phenomenon is avoided.

Description

technical field [0001] The present invention relates to the technical field of image forming devices, in particular to a color 3D printing method, a printing device and a terminal device. Background technique [0002] 3D (Three Dimensional, referred to as 3D) printing is a technology based on three-dimensional model slices and layer-by-layer processing to make 3D objects, which can be used for rapid prototyping or additive manufacturing. [0003] In the prior art, 3D printing technologies for making 3D objects include Fused Deposition Modeling (FDM for short), Stereo Lithography Apparatus (SLA for short), and Selected Laser Sintering (SLS for short). ), layered entity technology (Laminated Object Manufacturing, referred to as LOM) or inkjet printing technology, etc. When the printed 3D model is in full color, it is necessary to identify the color information of the 3D model, and print objects of corresponding colors according to the color information of the model.

AI Technical Summary

Problems solved by technology

[0004] However, when the color of the slice layer in the printing process is consistent with the color of the background image of the slice layer, the printing system cannot distinguish the background information that does not need to be printed and the slice layer that needs to be printed under the color information, which is easy to cause confusion, resulting in non-printing or wrong printing situation occurs
