Embodiment Construction

[0019] In order to clearly understand the technical content of the present invention, the following examples are given for illustration.

[0020] The concrete steps of this method are as follows:

[0021] Step 1, obtain the STL format file;

[0022] Put the STL file of the color model to be printed into the slicing software;

[0023] Step 2, get the triangular surface and calculate the projection;

[0024] The slicing software obtains the triangular faces in the STL file, and calculates the projection of the triangular faces on the X / Y plane through the three-point coordinates of each triangular face;

[0025] Step 3, filter the projection;

[0026] Screen the projection of the triangular surface on the X / Y plane where the angle between the triangular surface and the X / Y plane is not equal to 90°;

[0027] Step 4, get the path;

[0028] Convert the screened projection into a path, that is, the path between the coordinates of the starting position of the projection and the...

Abstract

The invention discloses a color spraying method based on a colorful 3D printer. The color spraying method comprises the following steps that firstly, an STL format file is acquired; secondly, triangular faces are acquired, and projections are calculated; thirdly, the projections are screened; fourthly, paths are obtained; and fifthly, color spraying is carried out according to the paths. The colorspraying method has the beneficial effect of solving the problem that spraying is incomplete when the gradient of the contour line of a model is gentle.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a color spraying method based on a color 3D printer. Background technique [0002] 3D printer is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. The working principle of a 3D printer is to put data and raw materials in the 3D printer, and the printer prints out the model to be printed layer by layer according to the program. The color 3D printer is based on the ordinary FDM3D printer, and the printed model is sprayed with color to obtain a color model; currently, when the color 3D printer sprays the model on the market, the edge of the model, especially the slope of the model surface, is not calculated. In the slower places, the spraying was incomplete, resulting in low precision of color spraying on the surface of the model and an unattractive appearance. [0003] Therefore need a kind of method to solve the above-mentio...
