Abstract

The invention belongs to the technical field of 3D printing, specifically a 3D printing nozzle, comprising a feeding hopper, a curing pipe and a bullet-shaped discharge pipe, the top of the feeding hopper is connected with a feeding pipe; the feeding The bottom of the bucket communicates with the top of the curing tube; the inner wall of the curing tube is provided with an annular installation groove; the inner wall of the annular installation groove is fixedly connected with a transparent glass tube; the inside of the transparent glass tube is injected with nano-scattering ions The synchronous effect of the scattering tube and the transparent glass tube in the present invention makes the ultraviolet light emitted by the laser head scattered, and can irradiate the inside and outside of the light-curing material synchronously, so that the curing is more uniform, and through the mutual cooperation of the linkage ring and the scraping ring , to scrape the inside of the transparent glass tube to prevent the light-curing material from adhering to the inner wall of the transparent glass tube, thereby avoiding blockage.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, in particular to a 3D printing nozzle. Background technique [0002] Stereolithography printing technology is to design a three-dimensional solid model through CAD, use discrete programs to slice the model, design the scanning path of the laser, and use the generated data to accurately control the movement of the laser scanner and the lifting table. Then use a laser with a specific wavelength and intensity to irradiate the surface of the light-curing material according to the designed scanning path, so that it is solidified sequentially from point to line and from line to surface, so that a layer of resin in a specific area of ​​​​the surface is cured, and then the lifting table is in the vertical position. The height of one layer is lowered in the direction, and the cured layer will be covered with another layer of liquid resin, and then the second layer of scanning is performed to cure anot...
