Problems solved by technology

After the DLP printer finishes printing, when the printed model is removed from the printing platform, it is generally shoveled off from the printing platform with a shovel, and when the shovel is shoveling the model, the force-bearing area of ​​the bottom of the model is small, and The force is not uniform, it is easy to break the bottom of the model, making it a scrap, which reduces the printing efficiency (increased scrap rate)

Embodiment

[0018] The DLP photocuring 3D printer that is convenient to demoulding of the present embodiment is as Figure 1-Figure 4 As shown, it includes a workbench 6, a vertical lifting mechanism 1, a projector light source (not shown in the figure) and a resin tank 2 fixed on the workbench 6. The projector light source faces the resin tank, and the bottom of the vertical lifting mechanism is fixed with The printing forming platform 7, wherein the vertical lifting mechanism 1 adopts a ball screw mechanism.

[0019] The printing forming platform 7 includes a handle 11, a push rod 16, a bottom plate 17, and a top plate 13 that is fixedly connected to the bottom plate 17 through the side plates. The bottom plate 17, the side plates, and the top plate 13 are combined to form a frame structure, and the bottom plate 17 and the side plates are integrally formed. The top plate 13 is fixedly connected to the side plates by fastening screws; the frame structure is provided with a fixed plate 14...

Abstract

The invention relates to a DLP 3D printer beneficial to model releasing. The DLP 3D printer beneficial to model releasing comprises a workbench, a vertical lifting mechanism and a resin tank. The bottom of the vertical lifting mechanism is fixedly connected with a printing forming platform. The printing forming platform comprises a handle, ejector rods, a bottom plate and a top plate fixedly connected with the bottom plate through side plates. A fixing plate is arranged in a frame structure formed by combining the bottom plate, the side plates and the top plate. Through holes allowing the ejector rods to penetrate through are formed in the bottom plate. One end of each ejector rod is fixedly connected with the fixing plate, and the other end of each ejector rod is inserted into the corresponding through hole and can reciprocate up and down along the through hole. The handle is connected with the top plate in a threaded mode and is fixedly connected with the fixing plate after penetrating through the top plate. By adoption of the printer, the rejection rate of printed finished products can be decreased, and accordingly the printing efficiency is improved.

Description

technical field [0001] The invention relates to a DLP photocuring 3D printer that is easy to demould, and belongs to the technical field of 3D printing. Background technique [0002] Photolithography (DLP) technology is currently the most in-depth research, the most mature technology, and the most widely used 3D printing technology in the world. Photocurable molding printers (DLP printers) use photocurable resins as molding materials, irradiate with ultraviolet light or other light sources, trigger photochemical reactions, and cure and shape the exposed liquid photocurable resins. [0003] The DLP light-curing 3D printer includes a printer frame, a projector light source, a printing forming platform, and a resin tank. The DLP printer drives the printing forming platform to move up and down in the resin tank through a vertical lifting mechanism, and the resin tank is filled with light-curing resin. The projector light source It is projected onto the bottom of the resin tank,...
