Description

Technical Field

[0001] This application relates to the technical field of 3D printers, specifically to a method and device for manufacturing extremely thin and strong dental veneers based on 3D printers. Background Art

[0002] A 3D printer is a device that manufactures three-dimensional entities by stacking materials layer by layer. It belongs to additive manufacturing technology. Different from traditional machining, 3D printing directly constructs objects through digital models and is suitable for complex structures, personalized customization, and rapid prototyping.

[0003] During the manufacturing process of dental veneers, the method of using photocurable resin materials is commonly used. The 3D printing device can manufacture dental veneers with high precision, high standards, and high fitting according to the complete dental digital model.

[0004] However, there are air bubbles inside the resin raw material. During the construction of large models, the tiny air bubbles can provide a certain supporting force for the device. When manufacturing dental veneers, due to the thin thickness of the dental veneers, the tiny air bubbles contained in the resin raw material will cause the middle of the dental veneer to be hollow, affecting the overall strength of the dental veneer. When the user bites forcefully, problems such as cracks and breakage of the dental veneer are likely to occur.

[0005] Therefore, it is necessary to provide a method and device for manufacturing extremely thin and strong dental veneers based on 3D printers to solve the above problems. Summary of the Invention

[0015] Further, the specific manufacturing method is as follows;

[0016] First, the user uses a scanner to scan the oral teeth, so that the scanner obtains a three-dimensional model of the oral teeth. Modeling is carried out according to the tooth model, and the surface in contact with the teeth is modeled as a diamond grid surface with a thickness of 0.5 mm, and the model is imported into the 3D printer. When the digital preparation stage is completed and the data in the 3D printer is ready, resin is poured into the centrifugal component. The cap component is pressed down so that the locking plate cooperates with the inner cylinder pull rod. The first driver is started to drive the tapping block, the locking plate and the inner cylinder pull rod to rotate. The centrifugal force throws the air inside the resin to the central position. When the first driver rotates, two rotating wheels are driven to rotate through the transmission belt. The two rotating wheels drive the two transmission rods to rotate, and the two transmission rods drive the two vortex fans to rotate. When the vortex fans rotate, the middle positioning plate is evacuated through the air extraction pipeline, and the air bubbles burst and are discharged outside the device. When the air bubbles are discharged, the device continues to rotate. The solenoid valve is started to open the solenoid valve, and the inside of the device is in a negative pressure state. The resin flows into the solution tank along the pipeline. When the user needs to scrape the resin, the second driver is started. The second driver starts to drive the second threaded rod to rotate. The second threaded rod rotates to drive the top plate to move. The second threaded rod rotates to drive the acceleration rod to rotate. The acceleration rod drives the vibration cam to rotate. When the vibration cam rotates, it squeezes the protrusion plate to drive the bottom plate to generate high-frequency vibration through the spring rod.

[0017] The beneficial effects of this application are:

[0018] The method and device for manufacturing an extremely thin and tough tooth patch based on a 3D printer provided by this application can, by providing an exhaust device, remove the tiny air bubbles inside the resin by the action of centrifugal force when pouring the resin into the device, avoiding the problem that the patch is hollow inside due to the air bubbles contained in the resin poured into the device.

[0019] By providing a vacuum pumping component, the air generated by the bursting of air bubbles in the exhaust device can be discharged outside the device, so that a pressure difference is realized between the inside and the outside of the exhaust device, and the air bubbles inside the exhaust device are more easily separated from the resin. At the same time, the pressure difference will also provide a thrust to help the resin flow out quickly when the resin flows out.

[0020] By setting a vibration component, it is possible to achieve further spreading of the device resin by high-speed vibration during leveling. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The locking ring 2034 is arranged as an inverted cone, and the upward-facing surface of the locking plate 2038 is arranged as an inclined surface.

[0047] Working principle:

[0048] Before using the device, first check each component of the device to ensure that all components of the device are properly coordinated and that the device can work properly.

[0049] When the device is working, first power on the device.

[0050] The user first uses a scanner to scan the oral teeth, so that the scanner obtains a three-dimensional model of the oral teeth. Modeling is carried out according to the tooth model, and the surface in contact with the teeth is modeled into a diamond grid-shaped mesh surface with a thickness of 0.5 mm, and the model is imported into the 3D printer.

[0051] When the digital preparation stage is completed and the data in the 3D printer is ready, pour the resin into the inside of the centrifugal component 204, press down the cap component 205, so that the cap component 205 drives the tapping block 2055 to move, and the movement of the tapping block 2055 drives the locking plate 2054 to move. When the cap component 205 moves, the sliding column 2057 extends downward from the output shaft of the first driver 209. When the cap component 205 moves, it drives the ejector rod 2035 to move, and the movement of the ejector rod 2035 drives the locking ring 2034 to move. The movement of the locking ring 2034 compresses the first elastic member 203. When the locking ring 2034 contacts the locking plate 2038, the locking ring 2034 pushes open the locking plate 2038. When the locking ring 2034 passes the locking plate 2038, the sliding plate 2039 pushes the sliding plate 2039 and the locking plate 2038 to move, realizing the locking of the locking ring 2034. When the locking ring 2034 is locked, the cap component 205 is no longer pushed up by the elastic force of the first elastic member 203. The locking plate 2054 cooperates with the inner cylinder pull-out rod 2042, and the first driver 209 is started so that the first driver 209 drives the tapping block 2055, the locking plate 2054 and the inner cylinder pull-out rod 2042 to rotate, and the centrifugal force throws the air inside the resin to the central position.

[0052] When the first driver 209 rotates, it drives the two runners 305 to rotate through the transmission belt 307. The rotation of the two runners 305 drives the two transmission rods 302 to rotate. The rotation of the two transmission rods 302 drives the two vortex fans 3013 to rotate. When the vortex fans 3013 rotate, the middle positioning plate 304 is evacuated through the air extraction pipe 303, and the air is discharged through the exhaust port opened on one side of the vacuum structure 301, and the bubbles burst and are discharged outside the device.

[0053] When the bubbles are discharged completely, the device continues to rotate, and the solenoid valve 2044 is started to open the solenoid valve 2044. The inside of the device is in a negative pressure state, and the resin flows into the inside of the solution tank 107 along the pipeline.

[0054] When the user needs to level the resin, the top plate 412 is flush with the resin horizontal plane, and the second driver 402 is activated. When the second driver 402 is activated, it drives the second threaded rod 408 to rotate. The rotation of the second threaded rod 408 drives the top plate 412 to move. The rotation of the second threaded rod 408 drives the acceleration rod 409 to rotate. The acceleration rod 409 drives the vibration cam 410 to rotate. When the vibration cam 410 rotates, it squeezes the convex plate 414, thereby driving the bottom plate 413 to generate high-frequency vibration through the spring rod 415. The vibration force assists in leveling the resin and expelling air bubbles.

[0055] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
