  • Composite transparent film, preparation method thereof, and method for continuous digital light processing ceramic 3D printing based on the same
    Patent number: 12090683
    Abstract: A composite transparent film, a preparation method thereof and a method for continuous digital light processing ceramic 3D printing based on the same are provided. The method selects a mixture of silica microspheres and PDMS to form a composite film on which silica is used to form a hydrophobic layer. Combined with specific optimized parameters, the film is more suitable for continuous digital light processing ceramic 3D printing, which can realize the continuous printing of ceramic slurries, solve the problem of delamination of printed pieces obtained by the existing 3D printing method of ceramics, improve the printing accuracy, and decrease the printing costs.
