In the field of 3D printing technology, there are a variety of different 3D printing methods. The photocuring 3D printing method comprises the steps of irradiating a photosensitive material by utilizing ultraviolet light or a light source 2 with other specific wavelength ranges and initiating a photochemical reaction, so that the photosensitive material in an area irradiated by the light source 2 is solidified into a solidified layer from a liquid state, and an object to be molded can be obtained after solidification layer by layer until a final printing model is obtained. The photosensitive material is usually a photosensitive resin, which is also called ultraviolet curing shadowless glue, and can be rapidly converted from a liquid state to a solid state under the irradiation of ultraviolet light with a specific wavelength (300nm-410 nm).
However, a small amount of liquid photosensitive material is attached to the solid printing mold, and the liquid photosensitive material has a certain viscosity, so that a small amount of liquid photosensitive material is attached to the surface of the printing mold. In the prior art, a specific cleaning solution is usually used to remove the liquid photosensitive material attached to the surface of the printing mold, wherein the most commonly used cleaning solution is ethanol, because the photosensitive resin is easily dissolved in ethanol. However, after the cleaning solution is used for many times, a large amount of liquid photosensitive materials are mixed in the cleaning solution, and the cleaning effect of the cleaning solution is further remarkably reduced. Therefore, it is necessary to treat the cleaning liquid mixed with the photosensitive material to improve the cleaning power of the cleaning liquid. The existing cleaning solution treatment method is to evaporate and recover the cleaning solution by utilizing the characteristic that the boiling point of the cleaning solution is lower than that of the photosensitive material. However, the method has high energy consumption and complex process, thereby increasing the treatment cost of the cleaning solution.
In order to reduce the treatment cost of the cleaning solution, as shown in fig. 1 to 3, the present invention provides a cleaning solution treatment apparatus which is low in energy consumption and simple in treatment process. Specifically, the cleaning solution treatment apparatus includes a reservoir 1, a light source 2, and a filter 3. As shown in fig. 2, the liquid storage container 1 is used for storing the cleaning liquid mixed with the liquid photosensitive material, and the light source 2 is used for emitting light with a specific wavelength toward the cleaning liquid mixed with the liquid photosensitive material in the liquid storage container 1, under the irradiation of ultraviolet light with the specific wavelength, the liquid photosensitive material in the liquid storage container 1 is solidified to become the solid photosensitive material, and the cleaning liquid in the liquid storage container 1 is still in a liquid state. In fig. 2, the cleaning solution mixed with the liquid photosensitive material is in the left liquid storage container 1, the cleaning solution precipitated with the solid photosensitive material is in the middle liquid storage container 1 in fig. 2, and the cleaning solution not containing the photosensitive material is in the right liquid storage container 1 in fig. 2. The light source 2 provided by the invention is an ultraviolet lamp, and the ultraviolet lamp can emit ultraviolet light with the wavelength of 355nm or 405 nm. The filter 3 is used for filtering the cured photosensitive material in the cleaning solution, so that, as shown in fig. 3, after the cleaning solution mixed with the solid photosensitive material is filtered by the filter 3, the separation of the solid photosensitive material and the cleaning solution can be realized. Compared with the existing method for recovering the cleaning liquid in an evaporation mode, the cleaning liquid treatment equipment provided by the invention is simpler, and the energy consumption of the cleaning liquid treatment method is lower, so that the treatment cost of the cleaning liquid is obviously reduced.

Even the material of stock solution container 1 is the printing opacity material, the ultraviolet ray also has certain loss through the in-process of stock solution container 1, and specifically, the outer wall of stock solution container 1 can reflect and absorb a part of ultraviolet ray. Thus, by providing the opening 11 at the upper end of the reservoir 1, the loss of ultraviolet light into the reservoir 1 is reduced.

Similarly, one end of the third lamp panel 23 close to the first lamp panel 21 is connected to the first mounting plate 51, and the other end extends obliquely downward, so that light emitted by the third lamp panel 23 is emitted into the liquid storage container 1 through the opening 11 and the side wall of the liquid storage container 1. The liquid storage container 1 is arranged on the upper end face of the second mounting plate 52, and the opening 11 of the liquid storage container 1 is opposite to the first lamp panel 21.
In order to facilitate the flow of the cleaning liquid in the reservoir 1 into the filter 3, in one embodiment, as shown in fig. 1 and 3, the reservoir 1, the filter 3 and the liquid pump 4 are connected in series via a pipe 8 to form a loop, and the liquid pump 4 provides power to move the cleaning liquid from the reservoir 1 to the filter 3 and back to the reservoir 1 via the liquid pump 4. So, realized the circulation flow of washing liquid between stock solution container 1 and filter 3 through liquid pump 4, be favorable to filter 3 to carry out a lot of filtration to the washing liquid to the solid-state photosensitive material that contains in the washing liquid that has significantly reduced has improved the purity of washing liquid.
