Photocuring 3D printer

Abstract

The invention relates to the technical field of 3D printing equipment, and discloses a photocuring 3D printer. The photocuring 3D printer comprises a box body, wherein a DLP projector is fixedly installed in an inner cavity of the box body, a light transmitting groove is formed in the top of the box body, tempered glass is fixedly installed on the upper surface of the box body, and liquid groovesare fixedly formed in the periphery of the upper surface of the tempered glass. According to the photocuring 3D printer, when a hydraulic device pushes the liquid grooves to move left and right, staggered power-on and power-off of two electromagnets are controlled, so that scraper blades with magnet components are attracted to rotate in a reciprocating mode under staggered power-off of the electromagnets, a rotating sleeve is controlled to rotate to drive the four scraper blades to completely cover and slide the upper surface of a forming platform plate, after the forming platform plate ascends, liquid resin adhering to the upper surface of the forming platform plate can be scraped away in time, the situation that after a curing part is formed, the forming platform plate moves upwards to be removed, then much time needs to be consumed for resin dripping is avoided, and the using efficiency of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a photocuring 3D printer. Background technique [0002] The light-curing 3D printer irradiates the liquid light-curable resin with ultraviolet light or other light sources in a specific wavelength range and triggers a photochemical reaction, so that the light-curable resin in the area irradiated by the light source is solidified from the liquid state, and the object to be formed can be obtained after being cured layer by layer. , are widely used in industrial product concept design, rapid tooling manufacturing and medical applications. [0003] In the existing light-curing 3D printers, a certain amount of liquid resin is first injected into the liquid tank, the forming platform is matched with the cantilever, and the forming platform is horizontally matched with the liquid tank, and the rotation of the lead screw is controlled by the motor, and the cantilever is con...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a light-curing 3D printer, which has the advantages of cleaner removal of small cured resins and shorter time for removing the firmware, and solves the problem that it is difficult to completely remove the small cured resins at the bottom of the liquid tank and it takes a lot of time to remove the firmware after it is formed. Issue with sticking liquid resin dripping for a significant amount of time
