Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0039] refer to figure 1 , The first embodiment of the present invention provides a three-dimensional printing device, which includes a forming tank 100 , a forming platform 200 , a pressure tank 300 and a communication pipeline 400 .

[0040] The forming tank 100 is used to contain the forming liquid 10 . The bottom of the forming tank 100 protrudes into the forming tank 100 to form a forming area 110 , and the top surface of the forming area 110 is preferably a horizontal plane. The forming liquid 10 is preferably a photosensitive resin, which can be cured after being irradiated by ultraviolet light, and the depth of the water level of the forming liquid 10 is sufficient to subm...

Abstract

The present invention discloses a three-dimensional printing apparatus, which is used for solidifying and molding a molding liquid, and comprises a molding groove, a molding platform and a communication pipeline, wherein the molding groove is used for holding a molding liquid, the bottom portion of the molding groove projects towards the internal of the molding grove to form a molding region, a pressure groove is used for proving a predetermined pressure, one end of the communication pipeline is communicated to the pressure groove, and the other end of the communication pipeline is communicated to the molding groove and is between the top surface of the molding region and the bottom portion of the molding groove. According to the present invention, the pressure groove provides the predetermined pressure for the molding liquid to make the molding region be immersed in the molding liquid, and the liquid surface depth of the molding liquid in the molding groove can be accurately and stably maintained through the pressure groove.

Description

technical field [0001] The invention relates to a three-dimensional printing device, in particular to a three-dimensional printing device capable of maintaining the liquid surface depth of the forming liquid in the three-dimensional printing device. Background technique [0002] There are many different forming methods in the existing three-dimensional printing technology, one of which is to irradiate the liquid photosensitive resin with ultraviolet light to cure the photosensitive resin. A 3D printing device formed by curing a photosensitive resin generally includes a tank, an ultraviolet light source and a movable platform. The platform is immersed in the photosensitive resin, and then irradiated with ultraviolet light to form a thin layer of solid photosensitive resin on the platform. Then lift the platform up to raise the cured photosensitive resin to the liquid level, then repeat the above steps again on the bottom surface of this layer of cured photosensitive resin to...
