Photocuring three-dimensional printing material box and preparation method thereof, photocuring three-dimensional printing device and photocuring three-dimensional printing method

Abstract

The invention relates to a photocuring three-dimensional printing material box and a preparation method thereof, a photocuring three-dimensional printing device and a photocuring three-dimensional printing method, and belongs to the technical field of three-dimensional printing. The photocuring three-dimensional printing material box comprises a box body, a non-porous fluorine-containing polymer film and a fluorine-containing oil film; the non-porous fluorine-containing film is arranged on at least part of inner surface of a light-transmitting bottom plate; and the fluorine-containing oil filmis adsorbed on the surface, far away from the light-transmitting bottom plate, of the non-porous fluorine-containing polymer film. According to the material box and the preparation method thereof, the device and the method, by utilizing the good surface wettability and chemical affinity between the non-porous fluorine-containing polymer film and the fluorine-containing oil, fluorine-containing oil can be bound, and the non-porous fluorine-containing polymer film and the fluorine-containing oil can be tightly connected; the photocuring printing process is changed from solid-solid separating into solid-liquid separating so that drawing force in the release process can be effectively reduced, and the printing speed and the printing area are increased; and a printing interface is in a liquidstate, so that high-speed printing is achieved, and meanwhile, heat can be dissipated in time so as to ensure the stability of material.

Description

technical field [0001] The present application relates to the technical field of 3D printing, and in particular to a light-curing 3D printing cartridge and a preparation method thereof, a light-curing 3D printing device, and a light-curing 3D printing method. Background technique [0002] Digital Light Processing (DLP) 3D printing technology is a kind of additive manufacturing technology that prints the molding plate and moves from bottom to top, and uses ultraviolet projection to cure photosensitive resin layer by layer to manufacture three-dimensional objects. In the current DLP3D printing technology scheme, the separation method of the cured layer and the printing interface mostly adopts the release film separation method. If you want to separate the release film from the cured layer, you need to use the method of straight pulling or oblique pulling. The disadvantage of the Czochralski method is that the release force is too large, which will cause the release film to be ...

AI Technical Summary

Problems solved by technology

The defect of the Czochralski method is that the release force is too large, which will cause the release film to be damaged, the printing quality to decline, obvious horizontal lines to appear on the object, and even the object to fall on the printing interface, resulting in printing failure.

The diagonal pull method can reduce the pulling force, but it increases the delamination time due to more complex mechanical movements, which slows down the entire printing process
