1. A 3D printing manufacturing method for general-purpose fluorescent fluid photochemical microreactor, wherein the microreactor comprises a light channel, a reaction channel, output of light channel, input of light channel, output of reaction channel and input of reaction channel; the light channel is filled with a fluorescent fluid, and two ports of the light channel are sealed; the reaction channel is filled with a reactant solution, and the light channel is located around the reaction channel to ensure an occurrence of a photochemical reaction;
the 3D printing manufacturing method comprises:
(1) designing a model of the microreactor and printing the microreactor with a 3D printer, a tube diameter or cross-sectional side length of the light channel and the reaction channel are 0.5-1 mm, and a material is transparent photosensitive resin;
(2) curing the microreactor by a UV light;
(3) cleaning the microreactor with a mixture of ethanol and isopropanol, and ensuring that there is no resin residue in the channel, and then placing the microreactor under a UV lamp to cure for 2-10 hours;
(4) dissolving a fluorescent material in a solvent with a concentration of 0.1-1000 ppm, and then using a syringe to inject the fluorescent material in the solvent into the light channel and sealing two ends of the light channel tightly to obtain the general-purpose fluorescent fluid photochemical microreactor.
