[0054] specific implementation
[0055] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings. Apparently, the accompanying drawings describe only some examples of the application of the present invention rather than all examples.
[0056] Use the currently commonly used FDM to print PLA printing materials (white), and FDM print heads. The printing head does not move, and its nozzle is suspended in the air. When the printing head is working, PLA filaments can be obtained. Put the filament into the heated dye to over-dyed (CMYB four colors). In this way, the printing materials for 3D full-color printing are ready.
[0057] The control software for full-color 3D printing reads the g-code generated by the slicing software, and then reads the texture map information from the original model file. The g-code is the traditional non-colored printhead movement information. Slicing software has been iterated in multipl...

Abstract
The invention discloses a filament multi-chopping small-section full-color 3D printer and a use method thereof. The filament multi-chopping small-section full-color 3D printer comprises a material ramming rod and a drive thereof, a main path transmission capillary tube, a filament feeder, a branch conveying pipe, a heating capillary tube, a heating aluminum block and a three-dimensional moving part. The method comprises the following steps of cutting a colored filament printing material into tiny particles in a stainless steel capillary tube, and enabling the particles to be conveyed one by one in sequence and heated, and finally extruding colored molten filaments from a nozzle. According to the full-color and multi-material 3D printing method, the printing effect is fine and smooth, and the degree of fineness is high. The method is characterized in that fine filaments with the diameter of 0.25-0.3 mm and transition colors are used for printing materials, and the fine filaments are hit by magnetic force at high frequency for multiple times, so that the fine filaments are folded into very short small sections to form particles. And the particles are conveyed one by one and heated, fused colored filaments are obtained, and 3D printing is conducted according to an FDM method. According to the colored printing material dosage calculation, a colored printing model is utilized, and a water-soluble supporting material and a transparent material can be printed at the same time.
Description
technical field [0001] The present invention is mainly used in the field of three-dimensional printing. Background technique [0002] The inventor personally concluded that full-color 3D printing can be divided into "first dyeing method" and "post dyeing method" in terms of dyeing time. Generally speaking, the "post-dyeing method" is to first use various methods to complete a layer of white shape printing; then use 2D color printing ink cartridges to dye. Ink cartridge technology seems simple, but in fact the core technology is the chip. Therefore, the price of ink cartridges is relatively high, even in 2D printing, they are often recycled and refilled for repeated use. The "first dyeing method" dyes each layer before it is formed, which can bypass the ink cartridge, making the overall price of the equipment lower and easy to popularize. [0003] The invention of application number 201810977277.8. Although this invention is also suitable for FDM, it has many components a...
