Embodiment 1

[0031] Such as Figure 1 to Figure 9 As shown, a FDM type 3D printing nozzle based on the principle of color mixing and dyeing includes an integrated heating chamber 1 and a tapered nozzle 3. The heating chamber 1 is provided with an annular dyeing ring 4 and a nozzle for melting silk. Heating device, the center of the annular dyeing ring 4 is provided with a circular feeding port 44 for printing raw materials to pass through, and a closed annular channel 43 is provided in the entity of the dyeing ring 4 with the symmetrical center of the dyeing ring 4 as the center, The outer circular wall of the dyeing ring 4 is radially penetrated with a dyeing ring ink inlet 41 communicating with the annular passage 43, and the inner circular wall of the dyeing ring 4 is evenly provided with several communicating annular passages radially. 43 and the ink guide tube 42 of the feed port 44, the outer peripheral wall of the heating chamber 1 is also provided with the ink inlet 2 of the nozzle...

Embodiment 2

[0035] An FDM type 3D printing method based on the principle of color mixing and dyeing using the nozzle as described, comprising steps:

[0036] 1) The color recognition system uses slicing software to slice and layer the 3D model and obtain the position information and color information of each layer. The color information is stored in the model database corresponding to the slicing information in 24-bit RGB codes;

[0037] 2) Utilize the RGB code data to drive the movement of the color picking device of the external color mixer, take cyan, magenta, yellow, and black dyes from each primary color box 6 in proportion and send them to the mixing chamber 9 through the color picking pipeline 10 for color matching, After the toning is completed, it is transported to the dyeing ring 4 through the delivery pipeline 11;

[0038] 3) Extrude the printing filament according to the data information of model slicing and color picking, and control the X, Y, Z motors to drive the printing n...

Abstract

The invention provides an FDM type 3D print head based on the color mixing and dyeing principle. The print head comprises a heating chamber and a conical nozzle, wherein the heating chamber and the conical nozzle are integrated; an annular dyeing ring is arranged in the heating chamber, a round feed port allowing raw print materials to pass is formed in the center of the annular dyeing ring, an annular channel with the symmetry center of the dyeing ring as the circle center is arranged in a real body of the dyeing ring, a dyeing ring ink inlet communicating with the annular channel is formed in the outer circle wall of the dyeing ring in the radial direction in a penetrating mode, a plurality of ink guide pipes communicating with the annular channel and the feed port are uniformly arranged on the inner circle wall of the dyeing ring in the radial direction in a penetrating mode, and a nozzle ink inlet communicating with an externally-connected color mixer and the dyeing ring ink inlet is arranged in the outer peripheral wall of the heating chamber in a penetrating mode. The invention further discloses an FDM type 3D printing method based on the color mixing and dyeing principle. According to the FDM type 3D print head and the method based on the color mixing and dyeing principle, free color blending can be realized according to models, formation can be completed in one step, real full-color 3D printing can be realized, the structure is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to an FDM 3D printing method based on the principle of color mixing and dyeing and a nozzle structure device thereof. technical background [0002] With the maturity of 3D printing technology, its application is becoming more and more extensive, and the demand for full-color 3D printing is increasing, but the technical development level of full-color 3D printing is out of touch with it. Currently, there are two types of color printing technologies on the market: one is primary color printing followed by post-processing such as painting; the other is multi-nozzle printing in stages. None of these technologies are true full-color 3D printing. [0003] The inkjet 3D printing proposed by the present invention can realize true full-color printing, and the external color mixer is used to adjust the color, and the dye is transported to the dyeing ring at the nozzle, so as to realize random colo...
