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

Embodiment Construction

[0032] Three-inlet single-outlet nozzle substrate ( figure 2 Middle 1) is drawn from an alloy aluminum foam metal body with high heat insulation rate, cut into 25mm use length, and the section is set as a rectangular parallelepiped connected to the bottom structure of the trapezoid ( figure 2 ); the upper end of the cuboid base of the three-inlet and single-outlet nozzle ( image 3 Middle 2) There are 3 fixing screw holes passing through the base body of the three-inlet and single-outlet nozzle, the cuboid is perpendicular to the trapezoidal heating chamber ( figure 2 Middle 5) upper part, through ( image 3 Middle 2-1, 2-2) The two fixing screw holes are connected to the X and Y axis walking brackets.

[0033] A heating chamber ( figure 2 In 5), the heating chamber is arranged as a cylindrical through hole, and the inner diameter of the heating chamber is determined by the known heater ( figure 2 6) The size of the model depends on the middle of the bottom of the hea...

Abstract

The invention discloses a three-channel agglomeration squeezing nozzle suitable for being used in a stackable (FDM) color three dimensional printer control system for realizing precise printing. The nozzle guarantees completion of non-temperature-difference fusion of printing raw filaments with all colors in a nozzle agglomeration mixing stirring chamber during printing of a colorful three dimensional workpiece, and allows color filaments to be extruded in order to realize printing, true color and high precision. The agglomeration mixing stirring chamber is designed to be an embedded structure, so the technical problem of point heating is solved, and the feeding precision is improved, thereby the mechanical strength of the printing workpiece reaches the mechanical strength index of a material, and the nozzle is suitable for the plug-and-play standard of present three dimensional printers and accords with process requirements of large scale manufacturing, and also has the advantages of convenient maintenance and replacement, resource saving, energy consumption reduction, cost reduction, simple structure, stability and reliability.

Description

technical field [0001] The invention belongs to a color extrusion nozzle technology for a stacked (FDM) color three-dimensional stereo printer, specifically a technology that can realize the fusion of multiple single-color plastic filaments input in a mixing chamber, and can produce a rotating stirring action. After color mixing, it is a three-channel fusion extrusion nozzle that extrudes true-color 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 sy...
