[0008] As an improvement, the box body is provided with an inclined groove cooperating with the printing table to facilitate the cleaning roller to sweep the powder into the box body.

[0009] As an improvement, a pull plate is fixedly connected to one end of the box body, and the pull plate is provided with anti-slip grooves to facilitate pulling the box body.

[0010] As an improvement, a silent slide rail cooperating with the slide plate is provided in the limiting groove.

[0011] As an improvement, an L-shaped plate cooperating with the cleaning roller is provided on the printing table.

[0012] As an improvement, the surface of the slide plate fits against the inner wall of the limiting groove, which can improve the stability of the slide plate in the limiting groove.

[0013] (III) Beneficial effects

[0014] The advantages of the utility model compared with the prior art are: by utilizing the control system and the printing mechanism, the denture can be 3D printed on the printing table. After the printing is completed, the servo motor can drive the moving shell to move and drive the cleaning roller to rotate at the same time.
