Specifically, the column assembly 20 includes a guide rail, the guide rail is vertically installed on the upper surface of the cover plate 101 along the height direction of the whole 3D printer, and the forming platform assembly 30 includes a model platform, a slide block, a screw rod and a driving motor, wherein the driving motor is arranged on the frame 10, the model platform is connected with the slide block, the slide block is connected with the guide rail, meanwhile, a threaded hole is formed in the slide block, one end of the screw rod penetrates through the threaded hole in the slide block to be in threaded connection with the slide block, and the other end of the screw rod is connected with an output shaft on the driving motor through a coupler;

when the 3D printer works, starting a driving motor to enable the driving motor to indirectly drive the model platform to move towards the material box 40, and when the distance between the model platform and the bottom of the material box is a layer thickness distance, stopping the driving motor from rotating, and simultaneously sending color signals on each layer of slice files to a DLP projector on the 3D printer;

the DMD chip on a DLP projector is then adjusted, for example, to have 1024 x 768 small mirrors in total on a single DMD, each mirror representing a pixel, each small mirror having the ability to independently control the switching of light. The angle of the light reflected by the small reflector is controlled by a video signal, the video signal is modulated by a Digital Light Processor (DLP), the video signal is modulated into a pulse width modulation signal with the same amplitude, the time for opening and closing a light path of the small reflector is controlled by the pulse width, and gray level images with different brightness are generated on a screen, so that the gray level images are matched with color signals on each layer of sliced files;

In some embodiments, the resin mixture 60 herein includes a photosensitive resin and a temperature-sensitive color master, and after the photosensitive resin irradiated by ultraviolet light is cured on the molding platform assembly 30, the light emitted from the DLP projector 50 is irradiated onto the temperature-sensitive color master in the photosensitive resin cured on the molding platform assembly 30, so that the color of the cured photosensitive resin may be changed.

Photosensitive resin is a printing material which is in a stable liquid state under the state of raw materials, and the resin generally comprises polymer monomers, prepolymers, ultraviolet initiators and other components, and can be instantly cured by the irradiation of ultraviolet laser in the printing process. Therefore, the printing consumables have good surface drying performance, smooth and clean surface after molding, high product resolution, excellent detail display and even better quality than injection molding products. These outstanding advantages make photosensitive resins the material of choice for high-end, artistic 3D printed products. However, the cost of the current photosensitive resin is still high, and the mechanical strength, heat resistance and weather resistance of the current photosensitive resin are mostly lower than those of engineering plastic consumables for FDM, which affects the application range of the material to a certain extent. The currently reported photosensitive resins for 3D printing are various in types and are actively researched and developed, but have limited practicability and commercialization, and the main types include epoxy acrylates, unsaturated polyesters, urethane acrylates and the like, and the resins have different advantages and disadvantages, wherein the epoxy acrylates have the advantages of high hardness, small volume shrinkage, good chemical stability and the like after curing, but have high viscosity and are not beneficial to molding processing; the unsaturated polyester has proper viscosity and is easy to form, but the hardness and the strength are poor after curing, and the unsaturated polyester is easy to shrink; the polyurethane acrylate has better toughness, wear resistance and optical property, but the polymerization activity and the chromaticity control are difficult. Therefore, the commercial photosensitive resin is often a combination of multiple photosensitive polymers to achieve the effect of making up for the deficiencies. For example, the novel photosensitive resin with moderate viscosity, good photosensitivity, small volume shrinkage of a cured product, good mechanical property and good thermal property is prepared by blending alicyclic glycidyl ester, bisphenol A epoxy resin, epoxy acrylate, alicyclic epoxy resin, 1, 4-cyclohexanedimethanol divinyl ether, polypropylene glycol diglycidyl ether diacrylate and a proper initiator.

Compared with engineering plastics or bioplastic which needs to be prepared into wires or powder, the liquid photosensitive resin has greater flexibility in design and preparation, and can be blended, doped or molecularly cut according to actual requirements, so that the performance of the printing material is greatly improved or the 3D printing material with special performance is obtained. The 3D printing material with high molding speed, high mechanical strength and good dimensional stability is obtained by using nylon microspheres to modify photosensitive resin such as Yangguangsheng. Acrylic acid is synthesized into aldehyde-removing functional molecules through the steps of epoxidation, diketene esterification and the like by Jiangyang and the like, and the molecules are used for synthesizing the formaldehyde-removing 3D printing photosensitive resin.
