The application discloses a kind of photo-curing 3D printing release devices and methods, first by import to the first chamber into lubricant, and make the lubricant can flow after flowing through the first chamber from outlet, simultaneously make the lubricant in the first chamber can be penetrated into the permeation membrane and form a layer of isolation layer on the upper surface of permeation membrane, after forming isolation layer, then inject photo-curing 3D printing forming material into the second chamber, then make external light source can be sequentially penetrated by from bottom to top through light-transmitting bottom wall, lubricant in the first chamber and permeation membrane, to make photo-curing 3D printing forming material in the second chamber photo-curing forming, and then make the forming product and permeation membrane have good release effect, simultaneously also make the application need not to be separately set release film when using, avoid the product forming quality to be affected due to the technical defects of poor release effect.

The application belongs to the technical field of anti-counterfeiting paint preparation, and particularly relates to a kind of invisible fluorescent inkjet material and its preparation method and application, invisible fluorescent inkjet material, by mass parts, including the following components: ultraviolet excitation fluorescent material 1-10 parts, adhesive 15-30 parts, penetration control agent 0.5-5 parts, heat-resistant stabilizer 0.1-2 parts, rheological modifier 0.1-1 part, water 50-85 parts;The penetration control agent includes silane coupling agent and high molecular penetration agent, and the mass ratio of silane coupling agent and high molecular penetration agent is 1-5:5-1;High molecular penetration agent is selected from polyethylene glycol, hydroxypropyl methyl cellulose or polyvinylpyrrolidone.The information of inkjet is invisible under visible light, and is developed clearly under specific wavelength ultraviolet light.
