Embodiment Construction

[0027] The present invention will be further described in conjunction with embodiment now.

[0028] A kind of colorful 3D printing method, comprises the following steps:

[0029] S1. Slicing processing, the three-dimensional model is subjected to structural slicing processing and color slicing processing, and then a structural slicing layer and a color slicing layer are generated, and the structural slicing layer and the color slicing layer are sequentially superimposed;

[0030] S2. Print the structural slice layer, the discharge pipe connected to the material box transports the printing material to the forming tank, and the forming bottom plate in the forming tank controls the layer thickness of the structural slice layer;

[0031] S3, scraping, the scraper scrapes the printing material in the forming tank along the top of the forming tank, so that the printing material is flatly spread in the forming tank, and the forming tank is completely covered;

[0032] S4, photocurin...

Abstract

The invention relates to a colorful 3D printing method. The colorful 3D printing method comprises the following steps that a three-dimensional model is subjected to structure slicing processing and color slicing processing, structure slice layers and color slice layers are generated, and the structure slice layers and the color slice layers are sequentially stacked; a discharge pipe connected to amaterial box conveys a printing raw material into a forming tank; a scraper blade scrapes and flattens the printing raw material in the forming tank along the top of the forming tank, the printing raw material is spread in the forming tank, and the forming tank is covered with the printing raw material; photocuring is carried out after the scraper blade scrapes and flattens the printing raw material, a structural outline is formed, and colorful spraying is carried out by a color printing head on the formed structure outline according to the color slice layers; then a forming base plate descends by one structure slice layer; and the above steps are repeated until printing is completed. A product printed by the method has various colors, meanwhile multiple colors exist on each layer, and the whole product is colorful and gorgeous.

Description

technical field [0001] The invention relates to a 3D printing method, in particular to a colorful 3D printing method. Background technique [0002] The existing photocuring 3D printing technology is mainly based on the principle of lamination manufacturing. The computer obtains the solidified geometric parameters of each layer by layering the 3D model, and then constructs the object by printing layer by layer. [0003] For products with color requirements, it is mostly used to add color masterbatch to the photosensitive resin, so that the formed product has color. But the color of the product formed by this method is single, and it is impossible to make multiple colors. Contents of the invention [0004] In order to solve the above problems, the present invention provides a colorful 3D printing method capable of printing out colored products. The specific technical solution is: [0005] A kind of colorful 3D printing method, comprises the following steps: [0006] S1. ...
