Self-radiating type 3D printing multi-nozzles

Abstract

The invention discloses self-radiating type 3D printing multi-nozzles, and relates to the field of 3D printing. The self-radiating type 3D printing multi-nozzles comprise a radiating shell, a first throat tube, a second throat tube, a third throat tube, a heating shell, a first spraying nozzle, a second spraying nozzle and a third spraying nozzle; fins are arranged outside the radiating shell, theupper end faces and the lower end faces of the fins are provided with radiating plates with inclined faces, disc dividing devices are arranged at the upper ends of the radiating shell, the first spraying nozzle, the second spraying nozzle and the third spraying nozzle are arranged at the lower end of the heating shell, and the first throat tube, the second throat tube and the third throat tube sequentially penetrate the disc dividing device, the radiating shell and the heating shell from top to bottom; and the lower end of the first throat tube is arranged at an inlet of the first spraying nozzle, the lower end of the second throat tube is arranged at an inlet of the second spraying nozzle, and the lower end of the third throat tube is arranged at an inlet of the third spraying nozzle. The self-radiating type 3D printing multi-nozzles have the self-radiating function, a printed product is provided with a surface material and a core material, the product strength can be greatly strengthened, different spraying nozzles are switched according to different colors of the product, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a self-radiating 3D printing multi-nozzle head. Background technique [0002] In recent years, 3D printing has developed rapidly, and with the continuous expansion of application fields, it has attracted more and more attention from all parties.

Problems solved by technology

However, if the temperature of the nozzle is too high, it will cause other parts to dissolve and burn. Therefore, a cooling device is required to control the temperature of the nozzle within a certain range. At this stage, a cooling fan is usually installed at the nozzle, but the cooling fan installed in this way can only Heat dissipation at one position of the nozzle, resulting in uneven heat dissipation, which affects the effect of heat dissipation, and requires an external circuit to supply power to the electric fan
