Double-nozzle 3D printer printing head device

Abstract

The invention discloses a double-nozzle 3D printer printing head device. The device comprises a nozzle module (1) and a nozzle module (20), wherein the nozzle module (1) is inserted in a radiator (2), and is locked through a machine-processed rice screw; a quick joint (9) is assembled on the radiator (2) in a screwing or bonding mode; the nozzle module (20) is inserted in a radiator (19), and is locked through a machine-processed rice screw; a quick joint (10) is assembled on the radiator (19) in a screwing or bonding mode; the radiator (2) is assembled with a radiator connecting plate (6) through a screw; and the radiator (19) is assembled with a radiator connecting plate (17) through a screw.

Description

technical field [0001] The invention belongs to a printing head device of a double-nozzle 3D printer. Background technique [0002] FDM 3D printers have been used more and more by people, and at the same time, more and more printing technology requirements have emerged. It is found that many times the single nozzle printer has become the bottleneck of printing works. For example: in actual printing tasks, quite a few models must have support structures to print normally, but usually after printing the model, not only the support part is difficult to remove, but also the printing quality of the interface between the model part and the support part is often very poor. Difference. So someone came up with the idea of ​​printing with dual nozzles, using one of the nozzles to print the model body, and using the other nozzle to print the soluble support, so that the problem of support can be solved. Another type of printing demand for dual nozzles is to print models of differe...

AI Technical Summary

Problems solved by technology

For example: 1. The distance between the two nozzles is too large, resulting in a serious shrinkage of the effective printing area compared with the single-nozzle print head

2. During the printing process, the nozzles in the idle state will continuously flow out excess consumables. During the horizontal movement of the print head, the excess consumables will always hang on the printed model, causing color confusion and poor surface quality of the model. decline

3. After the two nozzles are newly assembled, or after the nozzle assembly is disassembled or replaced, there will always be a height difference between the two nozzles due to part processing errors or assembly errors, and it is difficult to adjust

During the printing process, the nozzle with a relatively low height will scratch the model, so that there will be mislayers or even the model will be scraped off halfway, and the final printing will fail
