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 fusion extrusion injection nozzle, which is provided with six wire inlets and one wire outlet. It is suitable for the stacking (FDM) full-color 3D printer control system capable of precise printing. Ensure that when printing colorful three-dimensional workpieces, the printing raw material filaments of various colors are fused without temperature difference in the fusion mixing chamber of the nozzle, and the colored filaments are extruded. Make the mechanical strength of the printed workpiece reach the mechanical strength index of the material, facilitate maintenance and replacement, save resources, reduce energy consumption, reduce costs, simple structure, stable and reliable.

Description

technical field [0001] The invention discloses a six-channel fusion extrusion nozzle for a stacked color three-dimensional printer, which belongs to a stacked (FDM) extrusion nozzle technology for a color three-dimensional printer, and is specifically a multi-color plastic filament that can be input Converging and melting in the mixing chamber, it can produce vortex stirring action for color mixing, and then extrude full-color grade printing filament from the lower end of the nozzle. The six-channel fusion extrusion 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 ...
