[0042] refer to figure 1 and figure 2 , the photocuring three-dimensional printer includes a control device 1, a printing platform 2, a photosensitive resin tank 4 and a light processing device 51, the printing platform 2 is located above the photosensitive resin tank 4 and is used to carry a three-dimensional object 3, and the photosensitive resin tank 4 is used to hold liquid photosensitive Resin 61, the photosensitive resin is used for curing and molding of the three-dimensional object 3, the printing platform 2 can move from low to high in the vertical direction during printing, and the light processing device 51 is located under the photosensitive resin tank 4 and can output curing light toward the printing platform 2 52. The curing light 52 can pass through the bottom of the photosensitive resin tank 4 and the photosensitive resin 61, and the photosensitive resin is cured and formed on the printing platform. The light processing device 51 can either use a fractional la...

[0057] The second embodiment mainly separates the three-dimensional object 3 imaging and color imaging, so the curing light includes model curing light and color curing light, and the wavelength of the curing light can be matched and output according to the photosensitive resin and quantum dots with different particle radii.

[0058] Photocuring 3D printer printing methods include:

[0059] The light processing device 51 outputs model curing light;

[0060] Model curing light passes through the photosensitive resin;

[0061] The model curing light cures the photosensitive resin on the printing platform 2 and forms a layer of the three-dimensional object 3;

[0062] The light processing device 51 outputs color curing light to the cured photosensitive resin, so that the quantum dots of this layer of the three-dimensional object 3 are excited by the color curing light and display colors, and different particle radii display different colors according to the color curing light of d...

Abstract

The invention provides a photosensitive resin composition, a photocuring three-dimensional printer and a printing method of the photocuring three-dimensional printer. The photocuring three-dimensionalprinter comprises a photosensitive resin tank, a printing platform and an optical processor. The photosensitive resin tank is loaded with liquid photosensitive resin which is used for curing moldingof a three-dimensional object. The printing platform can move in the vertical direction. The optical processor outputs curing lights to the printing platform. The photosensitive resin contains quantumdots. The curing lights pass through the photosensitive resin. The liquid photosensitive resin can contain the quantum dots which can display colors after being irradiated by lights with a specific wavelength, the photosensitive resin can be transparent or in other colors, thus, the photosensitive resin can be cured to be a preset model through the curing lights, the quantum dots can display colors, and photocuring color three-dimensional printing is achieved.

Description

technical field [0001] The invention relates to the field of three-dimensional printing, in particular to a photosensitive resin composition, a photocurable three-dimensional printer and a printing method of the photocurable three-dimensional printer. Background technique [0002] At present, DLP three-dimensional printing (three-dimensional printing) on ​​the market is a more commonly used 3D molding method. It mainly uses digital light processing (DLP) technology to project curing light from light processing devices such as projectors, and then realize curing light. Curing liquid photosensitive resin layer by layer, it is able to print objects with very fine resolution, beyond the typical FDM 3D printer. [0003] At present, DLP 3D printers are mainly composed of two parts: software and hardware. The hardware includes: printer frame, projector, printing platform, workbench and resin tank set on it. In the photosensitive resin tank. [0004] After the image signal generat...
