Abstract: A 3D printing device and method for integrated manufacturing of functionally gradient materials and three-dimensional structures. The device includes an active and passive mixing and printing module and a constraining and sacrificial layer printing module. An input end of the active mixing module connects to multiple anti-settling feeding modules, and an output end of the active mixing module connects to the passive mixing and printing module. The passive mixing and printing module and the constraining and sacrificial layer printing module are mounted on one side of an XYZ three-axis module. The constraining and sacrificial layer printing module connects to a constraining and sacrificial layer feeding module and prints and forms a functionally gradient three-dimensional structure. The 3D printing device and method of the invention can realize integrated manufacturing of continuous functionally gradient materials and complex three-dimensional structures, and have the advantages of high printing efficiency and low cost.

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.
