Immediate material-making type 3D method

Abstract

The invention discloses an immediate material-making type 3D method. In the same printing target layer, printing operations of printing areas are conducted one by one according to the sequence from the higher color brightness to the lower color brightness of all the printing areas. In this way, through combination with the brightness gradual change theory, the influence on subsequent filler from residual filler in a printing spray head can be avoided, thus color modulation is ensured, and printing precision is improved.

Description

technical field

[0001] The invention relates to the technical field of 3D printing, in particular to an instant material-making 3D method. Background technique

[0002] The emergence of 3D printers has opened a new door for the field of solid molding. However, at present, 3D printing is mostly realized by layering, especially in the field of color printing. In order to ensure accurate chromaticity, the nozzle must be cleaned when switching pigments, which wastes printing materials and affects printing speed. It is difficult to control the cost of 3D printing. , so as to limit the development of 3D printing. Contents of the invention

[0003] Based on the technical problems existing in the background technology, the present invention proposes a real-time material-making 3D method.

[0004] A kind of instant material preparation type 3D method that the present invention proposes, comprises the following steps:

Example Embodiment

[0029] Reference figure 1 , The instant 3D method of material preparation proposed by the present invention includes the following steps.

[0030] S1. Obtain the print model, and cut the print model in layers, and use each segmented layer as the print target layer from bottom to top. This step is the basis for 3D printing through the layering method.

[0031] S2. Divide the print target layer into multiple print areas according to colors, the number of print areas is equal to the number of colors used in the print target layer, and each print area is a pure color area. Through this step, the parts of the same color on the printing target layer can be summarized into the same printing area, so that when printing with the printing area as a unit, the parts of the same color can be printed together, which simplifies the color conversion work and is beneficial Improve printing efficiency and reduce the chance of color crosstalk in different areas.
