A multifunctional 3D printing head

Abstract

The invention relates to a multifunctional 3D printing head comprising a heat dissipation mechanism, a spray nozzle, discharging mechanisms arranged on the spray nozzle, a mixing mechanism, switching mechanisms and heaters, wherein the discharging mechanism comprises a feed port, a first discharge port and a first conveying channel; the mixing mechanism comprises a first motor, a screw rod, a second discharge port, a second conveying channel and a third conveying channel; each switching mechanism comprises a second motor, a baffle plate and a rotating shaft; the heat dissipation mechanism comprises a gathering box, a fan and a heat dissipation component; the heat dissipation component comprises a housing and a feed pipe. In the multifunctional 3D printing head, four discharging mechanisms are integrated on one spray nozzle which can introduce four types of raw material filaments at the same time or different times, the raw material filaments can be sprayed out after being molten in the discharging mechanisms or can be sprayed out after entering the mixing mechanism from the discharging mechanisms, the mixing mechanism can achieve extrusion after fully melting raw materials to prevent the spray nozzle from being blocked, and raw material filaments with a variety of colors can be mixed at the same time for color mixing.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a multifunctional 3D printing head. Background technique [0002] With the development of science and technology, 3D printing technology has been applied in many fields such as jewelry, footwear, industrial design, automobile, etc. 3D printer is a machine of rapid prototyping technology, which is based on a digital model file, using Bondable materials such as powdered metal or plastics are used to construct objects by layer-by-layer printing. [0003] At present, the 3D printing nozzle is the key component of the 3D printer, which is set on a stable walking mechanism and used to melt and extrude raw materials. Most of the existing 3D printer nozzles use one material corresponding to one nozzle, and it takes a lot of time to switch between nozzles during printing. This shortcoming is especially fatal for 3D printing, which itself prints very slowly. Secondly, multiple The st...

AI Technical Summary

Problems solved by technology

Most of the existing 3D printer nozzles use one material corresponding to one nozzle. It takes a lot of time to switch between nozzles during printing. This shortcoming is especially fatal for 3D printing, which itself prints very slowly. Secondly, multiple The structure of the nozzle nozzle is complex, takes up a lot of space, and the structure is not easy to stabilize, which affects the printing accuracy

[0004] At present, there is still a very prominent problem with the 3D printing nozzles, which is that the nozzles are easy to block.
