Printing head modular design based on 3D printer

Abstract

The invention discloses a printing head modular design based on a 3D printer. A printing head comprises an upper protection cover and a lower protection cover, a moving block is installed between the upper protection cover and the lower protection cover, a wiring board and a fast-plug connector are installed at the upper end of the moving block, a material extruding module is installed at the left end of the moving block, a cooling fan is installed at the right end of the moving block, and an automatic leveling module is installed at the front end of the moving block. The printing head modular design based on the 3D printer has the advantages that the upper protection cover and the lower protection cover are installed, not only is the effect of protecting and shielding circuits achieved, but also the air cooling shunting effect is achieved; automatic leveling miniaturization is achieved, and the problem that a traditional printer head is lack of an automatic leveling device, or the leveling device is overweight is solved; by means of the material extruding module, the weight of the printing head of the 3D printer is significantly reduced, the printing quality and accuracy are improved, and the printing speed is increased; meanwhile, the cooling fan is installed on the moving block, and the effects of radiating heat, preventing heat from moving upwards and cooling a printed model are achieved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a modular design of a printing head based on a 3D printer. Background technique [0002] 3D printing technology is one of the most potential rapid prototyping technologies at present. It is based on the computer three-dimensional design model, through the software layered discrete and numerical control forming system, using laser beams, hot-melt nozzles, etc. to process metal powder, ceramic powder, Special materials such as plastics and cell tissues are stacked and bonded layer by layer, and finally superimposed to form a physical product. It is suitable for new product development in fields such as mechanical engineering, electronic engineering, and biomedicine. 3D printing technology has the advantages of low cost, high system reliability, small equipment size, low noise, fast forming speed, etc. It has huge application potential and broad market prospects. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional desktop 3D printer print head on the market adopts two methods of near-end wire feeding and far-end wire feeding: the near-end wire feeding mechanism, the motor is assembled on the print head module, resulting in excessive weight, which limits the printing speed, while the far-end The end-feeding wire lacks an integrated design, and the traditional 3D printer print head has too many fans, and the automatic leveling module cannot be miniaturized, resulting in low space utilization; the high-end 3D printer print head has a complex structure due to the mold design, and it is difficult to open the mold. High cost, can only be mass-produced
