AI Technical Summary

Technical Problem

Existing photocuring 3D printers are inefficient when heating resins, and conventional constant temperature methods will lead to uneven temperatures in the printing chamber, creating unpleasant odors, and inconvenient cleaning.

Method used

A constant temperature mechanism of the photocuring printer is designed, using two peristaltic pumps to drive the resin to circulate between the storage tank and the printing tank, combining a detachable constant temperature unit and a flexible connected peristaltic pump pipeline to achieve efficient heating and temperature uniformity of the resin.

Benefits of technology

The resin is stable and efficiently heated, avoiding the problems of uneven temperature and unpleasant odors, while conveniently cleaning and maintaining flexibility in the printing space.

Abstract

The utility model relates to the field of 3d printers, and particularly discloses a photocuring printer constant temperature mechanism, which comprises a workbench, a control center, a lifting mechanism, a printing groove, a storage groove, a peristaltic pump and a constant temperature unit, the peristaltic pump drives resin to circularly flow in the printing groove and the storage groove, and the constant temperature unit is separated from or immersed in the resin in the storage groove in a lifting manner. The pipeline of the peristaltic pump is flexibly connected with the edge of the printing groove, and after the constant-temperature unit is arranged in the storage groove, the constant-temperature unit does not hinder the lifting motion of the printing plate and does not hinder the swinging of the printing groove. When in use, the resin can flow slowly, and the temperature of the resin can be maintained at 20-30 DEG C.
