Lifting structure for photocuring 3D printer

Abstract

The invention provides a lifting structure for a photocuring 3D printer. The lifting structure comprises a base, a lifting table, a connecting part and a forming part, wherein the forming part is fixedly connected with the connecting part, the lifting table is provided with a transmission part, the connecting part comprises a connecting end and two side parts symmetrically arranged on the two sides of the connecting end, the two side parts are both slidably connected with the lifting table, the transmission part is in transmission connection with the connecting end, the transmission part rotates to drive the forming part to do lifting motion, and at the moment, the two side parts slide on the lifting table. According to the lifting structure for the photocuring 3D printer, the two side parts are arranged and are slidably connected with the lifting table, and when the forming part does lifting motion, the side parts slide on the lifting table so that the lifting motion of the forming part is smooth, and the phenomena of shaking and inclining of a forming platform in the lifting motion process are avoided, so that the printing precision is improved.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a lifting structure of a photocuring 3D printer. Background technique [0002] Light-curing 3D printing technology is the earliest and oldest 3D printing technology in history. It has been favored by the 3D printing industry because of its advantages such as high printing precision and good surface finish. In recent years, with the advancement of material science, various functional liquid photosensitive resin materials with different functions have been developed, and their printing accuracy and speed have also been greatly improved. Therefore, light-curing 3D printing technology has received more and more attention. more attention. [0003] Chinese patent ZL2017114595552 discloses a lifting structure of a light-curing 3D printer, including a base, a trough for storing liquid photosensitive resin, a molding platform, and a lifting mechanism, wherein the trough and the lifti...
