Problems solved by technology

[0005] To sum up, in the light-curing 3D printer, when printing each layer of the printed body, there is adhesion between the cured resin and the resin pool film. Because the adhesive force between the printed body and the resin pool film is too large, it is easy to cause printing molding. defects or printing failures

Embodiment Construction

[0031] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0032] In the present disclosure, the term "up and down" refers to the orientation or positional relationship in which the product is habitually placed when in use, unless the contrary description is made, and it can be understood as up and down in the direction of gravity, which is also related to the accompanying drawings. The "up and down" in the middle figure correspond. In addition, it should be noted that the terms such as "first" and "second" are used to distinguish one element from another element, and do not have sequentiality and importance.

[0033] Refer to figure 1 with figure 2 , The present disclosure provides a resin pool, which includes a resin ...

Abstract

The invention relates to a resin pool and a photocuring 3D printer. The resin pool comprises a resin pool wall, a first film and a second film, the resin pool wall is through in the vertical direction, and a first opening located in the top and a second opening located in the bottom are formed in the resin pool wall; the first film and the second film are both arranged in the second opening, the first film is close to the first opening relative to the second film, the first film has the performance that water molecules can penetrate through the first film, and the second film has the performance that the water molecules are hindered from penetrating through the second film. The resin pool solves the problem that the bonding force between a printing body and a resin pool film is too large,the printing stability can be effectively guaranteed, and the printing precision is improved.

Description

Technical field [0001] The present disclosure relates to the field of 3D printing technology, and in particular, to a resin pool and a light-curing 3D printer. Background technique [0002] In the field of 3D (three dimensional) printing, rapid prototyping technology can be divided into multiple categories according to different materials, molding methods, etc., among which the more common is light curing rapid prototyping. The principle of light curing molding is to use the characteristics of the polymerization reaction of the photosensitive resin (UV) in the fluid state under light, and irradiate the light source according to the cross-sectional shape of the object to be molded to cure the resin in the fluid state. [0003] In light-curing 3D printers, the polymerization reaction of the photosensitive resin from a fluid state to a solid state is excited by light of a special wavelength. Therefore, the actual print shape of the current layer is theoretically the same as the shape...
