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.

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.

Disclosed are an instant mixing container. The container includes a main container and an inner container fitted inside the main container. A mutually isolated outer storage chamber and inner storage chamber are provided inside the main container and the inner container respectively. An opening is provided on the inner container, and when the opening is pressed, impacted or pulled by an external force and opens, the outer storage chamber and the inner storage chamber are in communication. The container can instantly mix two or more materials, several different materials are respectively filled to constitute an integrally formed product, and the container is convenient to use, is able to keep the materials for a long time, and has an anti-counterfeiting function.
