Problems solved by technology

3D printing technology requires ceramic ink to have fast curing ability. UV light curing is a relatively mature 3D printing technology, which has a high application prospect in 3D printing ceramics, but it also has some problems: UV light curing relies on Light-curable resins are used to achieve rapid curing, but these light-curable resins generally have high viscosity. After being formulated into ceramic inks, their fluidity is poor, and it is easy to cause pipelines and nozzles to be blocked.
[0005] In the above patents, traditional light-curing resins are used, and the solvent content in the prepared ceramic slurry is very low and the viscosity is high, so it is not suitable for inkjet 3D printing molding technology (requiring good fluidity of ceramic ink), and Only suitable for other 3D printing photo-curing technologies, such as ceramic paste in paste or dry powder
