Abstract

The invention discloses a ceramic powder discharging device for a 3D ceramic printer. The ceramic powder discharging device for the 3D ceramic printer comprises a solenoid valve, a cavity, a shaft ring baffle component, a nozzle, a powder cavity, a powder feeding pipe component and a ceramic powder storage unit, wherein the solenoid valve is arranged at the top end of the cavity; the powder cavity communicates with the cavity through the shaft ring baffle component; the nozzle is arranged at the lower end of the powder cavity; the powder feeding pipe component is arranged on the lower portion of the shaft ring baffle component and communicates with the upper portion of the nozzle; and the ceramic powder storage unit is perpendicularly arranged on the top of the powder feeding pipe component. The ceramic powder discharging device for the 3D ceramic printer is compact in structural design and can effectively prevent ceramic powder from caking and blocking the nozzle in the pressure discharging process.

Description

technical field [0001] The invention relates to the technical field of 3D printing and molding, in particular to a ceramic powder output device for a ceramic 3D printer. Background technique [0002] Direct Ink Writing is a new type of 3D printing technology for ceramic materials [J A Lewis. Colloidal processing of ceramics. Journal of the American Ceramic Society, 2000, 83(10): 2341-2359.]. This technology first designs the required three-dimensional structure pattern with the help of computer aided (CAD), and then automatically controls the ceramic powder powder conveying device installed on the Z axis by the computer, which consists of a needle cylinder and a needle nozzle. The powder extrudes a linear fluid of precise size from the nozzle, and at the same time, the X-Y axis moves according to the trajectory set by the program, depositing the linear fluid on the moving platform to obtain the first layer structure. After the first layer of molding is completed, the Z-axis...
