Color mixing device for 3D printer

Abstract

The invention belongs to the technical field of 3D printing, and particularly relates to a color mixing device for a 3D printer. The color mixing device comprises a fixed seat, a pushing assembly, a heating assembly, a mounting seat, a flow guide plate and a transmission assembly, a cavity is formed in the interior of the fixed seat, the pushing assembly is installed at the upper end of the fixed seat, the heating assembly is installed in the inner cavity in the interior of the fixed seat, the feeding end of the heating assembly is located right below the pushing assembly, a plurality of groups of first discharging holes are formed in the lower end of the heating assembly and are arranged in an annular array mode, and the mounting seat is mounted at the lower end of the fixed seat and is located right below the heating assembly. According to the color mixing device , through cooperative use of the fixed seat, the pushing assembly, the heating assembly, the mounting seat, the flow guide plate and the transmission assembly, an original 3D printer head assembly can be directly replaced, color mixing can be carried out on a printed piece while spraying is achieved, the structure is simple, the functions are comprehensive, and the practicability is high.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, in particular to a color mixing device for a 3D printer. Background technique [0002] 3D printing is a technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. [0003] Existing common 3D printers cannot perform color-mixing printing, but 3D printers dedicated to color-mixing printing all adopt the method of two-in-one-out nozzles or double nozzles for color-mixing printing. [0004] Among them, the two-in-one-out nozzle uses two sets of feeding holes to feed materials, and performs mixed-color printing through a set of printing nozzles; this type of nozzle has a complex structure and high cost. [0005] However, due to the difference in the positions of the two groups of nozzles when using the double-nozzle structure, the position of the nozzle needs to be changed every time the color is switched...

Problems solved by technology

[0003] Existing ordinary 3D printers cannot perform mixed-color printing, and 3D printers dedicated to mixed-color printing all use two-in-one-out nozzles or double-nozzle methods for mixed-color printing

[0004] Among them, the two-in-one-out nozzle uses two sets of feeding holes to feed materials, and performs mixed-color printing through a set of printing nozzles; this type of nozzle has a complex structure and high cost

[0005] However, due to the different positions of the two groups of nozzles when using the double-nozzle structure, the position of the nozzle needs to be changed every time the color is switched, which requires high precision and is prone to errors.
