Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a personalized tooth 3D printing device and method thereof. Background Art

[0002] 3D printer, i.e. a machine of rapid prototyping technology, is a technology that uses a digital model file as the basis, uses powdered metal or plastic and other bondable materials, and constructs objects by printing layer by layer. 3D printers with high efficiency and precision are gradually applied to the production process of teeth. Teeth are gradually formed on the operating platform through the workflow of the 3D printer. After searching, the Chinese patent publication number CN110962347B discloses an adjustable operating platform for a tooth 3D printer that is convenient for heat dissipation, which relates to the technical field of 3D printing equipment.

A mounting frame 56 is fixedly connected to the bottom end of the U-shaped plate 55, and the print head 6 is installed through the inside of the mounting frame 56. A mounting hole that matches the print head 6 is opened inside the mounting frame 56, and a bidirectional screw rod 57 is rotatably connected inside the mounting frame 56. The outer surface of the bidirectional screw rod 57 is symmetrically threaded with two clamping plates 58, and the inner wall of the clamping plate 58 is opened.

[0040] After the print head 6 is installed and fixed, the rotation of the third motor 71 can drive the one-way screw 72 to rotate, and the thread can drive the connecting plate 73 and the connecting head 74 to move, so that the connecting head 74 enters the concave groove 64 at the top of the connecting tube 63, and under the action of the convex sealing ring 75, the sealing between the connecting head 74 and the connecting tube 63 can be improved to avoid material leakage. Without the need for threaded connection, the installation speed of the print head 6 can be increased, thereby improving work efficiency and reducing the workload of maintenance personnel.

[0041] like Figure 1 , Fig. 9 and Fig.10As shown, an auxiliary molding mechanism 8 is installed between the top of the machine body 1 and the U-shaped frame 3, and the auxiliary molding mechanism 8 includes a first electric push rod 81 that passes through and is fixedly installed on the top of the U-shaped frame 3, and the bottom end of the first electric push rod 81 is fixedly connected to a cross plate 82, and one end of the cross plate 82 is fixedly connected to a support ring 83, and the inner wall of the support ring 83 is rotatably connected to a protective cover 84, and a second electric push rod 85 is fixedly installed on one side of the top of the protective cover 84, and the bottom end of the second electric push rod 85 is fixedly connected to an annular tube 86, and a plurality of blowing pipes 87 are fixedly connected to the inner wall of the annular tube 86 in an annular array, and the blowing pipes 87 are inclined.
