Problems solved by technology

However, in the conventional 3D printing device, a closed area is formed between the release film and the flat plate, resulting in a low-pressure area during the separation of the workpiece, making it difficult to separate the workpiece from the release film
[0003] Although the above problems can be separated by applying a greater pulling force to separate the workpiece and the release film, applying a greater pulling force will often cause the workpiece to be unable to support and be damaged, or the release film will be deformed due to excessive pulling

Embodiment Construction

[0025] see figure 1 , the liquid storage tank 100 of this embodiment is suitable for a three-dimensional printing device to accommodate the liquid photosensitive material 10 , and the liquid storage tank 100 includes a release layer 110 and a flat plate 130 . The release layer 110 has a workpiece forming region R. The workpiece forming area R is an area where the shaping beam provided by the three-dimensional printing device can be irradiated. The flat plate 130 supports the release layer 110, and has a first area R1 corresponding to the workpiece forming area R and a second area R2 next to the first area R1. There is at least one fluid channel 133 connected to the flat plate 130 in the second area R2. The surface 134 of the release layer 110 extends to another surface of the plate 130 , such as the surface 135 opposite to the surface 134 .

[0026] The above-mentioned liquid holding tank 100 also includes a plurality of side walls 120, for example, these side walls 120 are ...

Abstract

A liquid containing groove is suitable for a three-dimensional printing device for containing liquid photosensitive material. The liquid tank includes a film and a plate. The film has a working area, and the plate supports the film and has at least one fluid tunnel extending from a first surface of the plate contacting the film to a second surface of the plate. The motor is disposed on the liquid tank, providing dragging-down traction to incline the liquid tank. The embodiments of the present invention facilitate the separation of workpieces from the film. Another three-dimensional printing apparatus and a three-dimensional printing method are also provided.

Description

technical field [0001] The invention relates to a printing device, in particular to a three-dimensional printing device, a liquid storage tank and a printing method thereof. Background technique [0002] In the conventional photocurable 3D printing device, the bottom of the storage tank for accommodating the photosensitive resin has a release film and a flat plate supporting the release film. During the printing process of the workpiece, the photosensitive resin will be hardened and bonded to the On the release film, and then form one of the layers in the workpiece. In order to continue the printing of the next layer of workpiece, it is necessary to apply force to pull up the workpiece to separate the workpiece from the release film, so that the unhardened photosensitive resin can be refilled between the workpiece and the release film. However, in the conventional 3D printing device, a closed area is formed between the release film and the flat plate, resulting in a low-pre...
