Problems solved by technology

Its disadvantage is that the color will be affected by the difference in the white reference of gypsum powder, and the mechanical strength of gypsum powder is far lower than that of engineering plastics, so it cannot be used in engineering devices and other applications

Abstract

The invention discloses a six-channel aggregation-fusion type squeezing nozzle. The squeezing nozzle is provided with six thread inlets and one thread outlet and is suitable for a fused deposition modeling type (FDM) all-true color three-dimensional printer control system capable of achieving precision printing. Raw material printing threads of each color can be fused without a temperature difference in a nozzle aggregation fusion mixing and stirring cavity in a process of printing a color three-dimensional stereoscopic workpiece, the colored threads are extruded, a thread outlet caliber can be changed, and printing, all true color and high precision can be achieved. Accordingly, the mechanical strength of the printed workpiece reaches the mechanical strength index of the material, maintenance and replacement are convenient, resources are saved, energy consumption is reduced, the cost is reduced, and the nozzle is simple in structure, stable and reliable.

Description

technical field [0001] The invention belongs to a stacking (FDM) color three-dimensional printer squeeze nozzle technology, specifically a kind of technology that can realize the fusion of multiple single-color plastic filaments input in a mixing chamber, and can produce vortex stirring action for color mixing Finally, a six-channel fusion extrusion nozzle that extrudes full-color grade printing filament from the filament outlet at the lower end of the nozzle. Background technique [0002] The printing program of the stacked 3D printer in the known technology is developed on the basis of the printing program of the HP inkjet printer. During the stacked 3D printing process, the default printing material of the printing program is liquid flow. For the closing and feeding instructions of the print heads, the instruction to turn off the heating power supply of all the print heads is given only when the printing of the workpiece is finished. Therefore, the heater system in the s...
