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 pixe

Example Embodiment

[0050] Example 1

[0051] Such as figure 1 As shown, a color 3D printing device mainly includes: a computer system 100, a processor 101, a color slicing module 102, a control board (not shown), a working platform 211, a working platform transmission mechanism 212, a wire extrusion head 221, and a wire Extrusion head transmission mechanism 222, color inkjet head 231, inkjet head transmission mechanism 232, color ink cartridges (not shown).

[0052] The computer system 100 includes a processor (ie, CPU) 101, a memory (not shown), a USB interface (not shown), a keyboard and a mouse (not shown), and a color slice module 102 is installed in the computer system, The processor 101 completes the slicing of the color model by executing functions or instructions in the color slicing module 102.

[0053] Input the color model into the color slice module 102, the software can layer the model according to the layer thickness and the three-dimensional size of the model, obtain the cross section o...

Abstract

The invention relates to a full-color 3D printing device and a corresponding printing method. The device comprises a color slicing module, a control main board, a moving mechanism, a wire extrusion head, a work platform and color ink jet heads. By adoption of the device and on the basis of the FDM technology and the color ink jet printing technology, rapid forming of a color three-dimensional solid body is achieved. The method comprises the following steps that a three-dimensional solid model is established on a computer, and color adding is conducted; the color slicing module slices the model, and color slice files with color information are obtained; the files are input into a color 3D printer, layer-by-layer printing is conducted through the printer, and colors are added in corresponding areas of the surface of the layer; then, ink curing is conducted; and the whole process is repeatedly conducted till the model is printed. By means of the layer-by-layer 3D printing and coloring method, full-color printing of a complex three-dimensional structure can be achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to a 3D printing technology; a full-color 3D printing device and a full-color 3D printing method are specially designed. [0003] 【Background technique】 [0004] Fused deposition manufacturing, also known as melt line deposition manufacturing, is a processing method that does not use lasers. The FDM process was first successfully developed in 1988 by Dr. Scott Crump, an American scholar. The FDM forming system mainly includes five parts: extrusion head, wire feeding mechanism, motion mechanism, heating studio, and working table. The nozzle is scanned in XY linkage under computer control, and the wire is heated to slightly higher than its melting point in the nozzle. The spray head ejects the molten material in the scanning motion, rapidly cools to form a processing layer and is firmly connected with the previous layer. In this way, layers of scanning superposition form a spatial entity. [0005] At present, the objects...
