Problems solved by technology

[0005] When performing color imaging on a three-dimensional solid model, the filament material is generally mixed in the print head and then ejected from the print head to form a colored three-dimensional solid model. The color mixing makes the print head more complex than other monochrome print heads, so the cost of this color 3D printer is high, and the printing cost is relatively high
At the same time, because the print head cannot mix more colors, the color of the three-dimensional solid model is also more complicated, and it also causes low color reproduction and low image resolution, which brings inconvenience to users.

[0045] refer to image 3 , image 3 It is a flow chart of the printing method of the three-dimensional printer. When performing color solid imaging on the 3D solid model 19 , step S1 is first performed to start the 3D printer 1 . Then execute step S2, input the model file with three-dimensional solid model 19 data to the memory of three-dimensional printer 1, then execute step S3, the processor of three-dimensional printer according to such as Figure 4 The three-dimensional solid model 19 shown is sliced ​​and layered, the three-dimensional solid model 19 is a cone, and a through hole is opened along the axis Z of the three-dimensional solid model 19, and the three-dimensional solid model 19 is sliced ​​and divided along the axis Z through the processor. After layering, process the data of N layered models with different diameters, where a layered model such as Figure 5 The hierarchical model 192 is shown. Then step S4 is executed, and the processor divides each layered ...

[0051] On the basis of the first embodiment of the printing method of the above-mentioned three-dimensional printer, the imaging step S5 of the printing head 2 and the inkjet head 3 can also adopt such as Figure 7 In the sequence of steps, specifically, when step S5 is executed, step S54 is first executed, and the print head 2 ejects the silk material in a molten state according to the color area 193 and the color area 195 for solid imaging, and then step S55 is executed, inkjet The head 3 ejects ink on the layered model 192 according to the color area 193 and the color area 195. After the print head 2 and the inkjet head 3 complete the imaging of the color area, step S56 is performed. 194 ejecting the silk material in the molten state for solid imaging. Of course, the inkjet head 3 can also work simultaneously with the printhead 2, that is, the inkjet head 3 follows the movement track of the printhead 2, and the inkjet head 3 performs color imaging on the filament material j...

Abstract

The invention provides a three-dimensional printer, a printing method of the three-dimensional printer and a printing device of the printing method. The printing method of the three-dimensional printer comprises the following steps: starting the three-dimensional printer which comprises a printing head for entity imaging and an ink jet head for color imaging; inputting a model file with target entity model data into a memorizer; slicing and layering according to the target entity model data through a processor, processing and obtaining a plurality of layering model data; performing entity imaging according to each layering model data through the printing head; performing color imaging on the layering model according to the layering model data in the same layer through the ink jet head. The invention provides the printing device and the three-dimensional printer using the method. By performing color imaging on each layering model, the colorful printing of the overall three-dimensional entity is achieved finally, then the structure of the three-dimensional printer is simplified, and the three-dimensional printer has the advanstages of low imaging cost, high color reproduction accuracy, high image resolution ratio, simple imaging method and the like.

Description

technical field [0001] The invention relates to the field of printing, in particular to a three-dimensional printer, a printing method for the three-dimensional printer and a printing device for the three-dimensional printer. Background technique [0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses rapid prototyping technology. Based on digital model files, it uses molding materials to construct three-dimensional entities through cumulative molding. Before printing, it is necessary to use computer modeling software to model, and then "partition" the built 3D model into layer-by-layer sections, that is, slice and layer, so as to control the 3D printer to print layer by layer. [0003] Currently, there are three commonly used stratification methods. One is the equal layer height layering method, which is commonly used in most 3D printers; the other is the adaptive layering method for the STL model, which is based on the normal vector of the...
