Problems solved by technology

However, this solution has the following problems: the color of each pixel of the product to be printed may be different, therefore, the entire printing process needs to change colors continuously, and the amount of glue required for a single pixel is very small, and the pre-mixed method is used Printing is difficult to switch between different colors, and it is difficult to ensure that the glue of the previous color will not remain in the pre-mixer and affect the effect of the next color

Embodiment 1

[0052] like Figure 4 As shown, the color 3D printer of this embodiment includes a frame 300, a fuse stack is a 3D printing system and a coloring system.

[0053] The fuse stacking 3D printing system includes a worktable moving in the Z direction and its driving unit, a fuse printing head moving in the X-axis and Y-axis directions and its driving unit,

[0054] The Z-moving workbench and its drive unit include a heating workbench 210, a Z-moving platform 211, and a Z-direction servo motor 212. The heating workbench 210 is installed on the Z-direction moving platform 211, and the Z-direction servo motor 212 passes The Z-direction transmission unit 213 is transmitted with the Z-direction mobile platform, and is used to drive the Z-direction mobile platform 211 to move up and down along the frame.

[0055] The fuse printing head and its drive unit moving in the X-axis and Y-axis directions include a fuse printing head 220, an X-axis guide post 221, an X-direction servo motor 222...

Embodiment 2

[0059] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is only the color jet positioning drive unit, the color jet positioning drive unit of this embodiment and the drive unit of the print head 220 only share the Y-axis guide column 223, and the color jet positioning The drive unit adopts an X-axis guide column, an X-axis transmission unit, and a Y-axis transmission unit independent of the drive unit of the print head 220. To avoid redundant description, the following description mainly focuses on the differences from Embodiment 1, which are the same as Embodiment 1. The structural part can refer to the description of embodiment 1. like Figure 5 As shown, the reference numerals 221, 225, and 226 are respectively the X-axis guide column, the X-axis transmission unit, and the Y-axis transmission unit of the drive unit of the print head, while the reference numerals 131, 135, and 136 are respectively the positioning drive of the color jetting he...

Abstract

The invention discloses a colored 3D printing device and method. The colored 3D printing device comprises a fuse wire stacking type 3D printing system and is characterized by further comprising a coloring system which comprises a color spraying head, a pigment solidifying unit, a color spraying head positioning driving unit, a color control unit and a plurality of pigment supply units, wherein the color spraying head comprises a plurality of nozzles; the nozzles are connected with the pigment supply units in a one-to-one correspondence manner; the color spraying head positioning driving unit is used for driving the color spraying head to move along the appearance surface of a layer structure; the color control unit is used for receiving color data of the appearance surfaces of all the layer structures and controlling the pigment supply units according to the color data of the appearance surfaces so as to control the pigment spraying amounts of all pixel points on the appearance surfaces of the nozzles on the layer structures; the color spraying head is used for spraying pigments to the appearance surfaces of the layer structures through the multiple nozzles; the pigment solidifying unit is used for solidifying the pigments. The colored 3D printing device has the advantages of good coloring effect and high product consistency; furthermore, a hardened layer with certain thickness is formed on the surface of a product.

Description

technical field [0001] The present invention relates to 3D printing technology, in particular to a color 3D printing device and printing method. Background technique [0002] At present, the objects printed by 3D printers on the market have only one color, or a combination of several different color materials. After the printing is completed, the final object will be realized through the surface coloring treatment in the later stage. Most of them adopt the method of manual coloring. , there will be inconsistencies in the coloring treatment of the surface during mass production. [0003] The publication number is CN103434135A Chinese invention patent application "a color 3D printer and its method for preparing three-dimensional products" discloses a color 3D printer, according to the color to be printed, using a premixer to process red, yellow and blue three-color resin Mix to form the required color, and then print the mixed resin to finally obtain a colorful 3D product. H...
