Abstract
Description
Technical Field
[0001] This utility model relates to the field of support structure technology, and in particular to a support structure for laser 3D printed dentures. Background Technology
[0002] Dentures, commonly known as "false teeth," are artificial tooth replacements used to compensate for tooth loss caused by various reasons, restore oral functions such as chewing, pronunciation, and aesthetics, and maintain the normal shape and physiological balance of the oral cavity and maxillofacial region. In the laser 3D printing process of dentures, the support structure is an auxiliary structure added to ensure the smooth formation of the denture during the printing process. Since 3D printing is a layer-by-layer manufacturing process, there may be structures in the denture model that are difficult to form directly, such as suspended or thin-walled structures. The support structure is like the "scaffolding" of a building, providing temporary support for these parts and preventing material deformation and collapse during the printing process.
[0003] In existing technologies, the support materials used in the laser 3D printing of denture support structures are mostly solid structures. Solid structures consume a large amount of raw materials during the printing process, which significantly increases production costs. Furthermore, because solid structures require more material to be deposited, the printing time is also greatly extended. This not only reduces production efficiency but may also affect the product delivery cycle. Therefore, it is necessary to improve the support structure of laser 3D printed dentures to solve the above problems. Utility Model Content
[0004] To overcome the problem that solid structures not only consume a lot of raw materials during the printing process, but also reduce production efficiency.
[0005] The technical solution of this utility model is as follows: a support structure for laser 3D printed dentures, including a base frame, a support frame disposed on the top of the base frame, a top frame disposed on the top of the support frame, a first hollow groove opened on the support frame, a second hollow groove opened on the top frame, and an installation component disposed between the base frame, the support frame, and the top frame. The second hollow groove is disposed on the top of the first hollow groove, and the base frame, the support frame, and the top frame are installed and fixed by the installation component.
[0006] Preferably, there are several first hollowed-out grooves, which are arranged in a honeycomb pattern on the support frame.
[0007] Preferably, there are several second hollow slots, which are distributed sequentially on the top frame at positions corresponding to the first hollow slots.
[0008] Preferably, a protrusion is fixedly connected to one side of the support frame.
[0009] Preferably, the mounting assembly includes a first through hole in the support frame, a second through hole in the top frame, a third through hole in the base frame, a mounting bolt disposed inside the first through hole, a mounting nut disposed inside the base frame, the mounting bolt disposed inside the second through hole, the mounting bolt disposed inside the third through hole, the mounting bolt disposed inside the top frame, and the mounting nut threadedly connected to the outside of the mounting bolt.
[0010] Preferably, four sets of the first through hole, the second through hole, and the third through hole are provided, and the four sets of the first through hole, the second through hole, and the third through hole are distributed on the support frame, the top frame, and the bottom frame in sequence.
[0011] Preferably, the top frame has a matching storage groove at the corresponding position of the mounting bolt, and the mounting bolt is placed inside the storage groove of the top frame.
[0012] Preferably, the base frame has a matching storage slot at the corresponding position of the mounting nut, and the mounting nut is placed inside the storage slot of the base frame.
[0013] The beneficial effects of this utility model are:
[0014] By using the first and second hollow slots distributed in a honeycomb pattern on the support frame and top frame, the amount of raw materials used is reduced while ensuring the support strength, thus lowering the production cost. In addition, the amount of raw materials required for filling during the printing process is reduced, and the printing time is shortened accordingly, thereby speeding up the overall production process.
[0015] By installing the base frame, support frame, and top frame, it is easy to replace any damaged component, thereby reducing the overall operating cost and improving the practicality of the device. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a support structure for laser 3D printed dentures, including a base frame 1, a support frame 21 disposed on the top of the base frame 1, a top frame 22 disposed on the top of the support frame 21, a first hollow groove 23 formed on the support frame 21, a second hollow groove 24 formed on the top frame 22, and an installation assembly disposed between the base frame 1, the support frame 21, and the top frame 22. The second hollow groove 24 is disposed on the top of the first hollow groove 23. The base frame 1, the support frame 21, and the top frame 22 are installed and fixed by the installation assembly. Through the honeycomb-shaped distribution of the first hollow groove 23 and the second hollow groove 24 on the support frame 21 and the top frame 22, the amount of raw materials used is reduced while ensuring the support strength, thus reducing the production cost. In addition, the amount of raw materials required for filling during the printing process is reduced, and the printing time is shortened accordingly, thereby speeding up the overall production process. By installing the base frame 1, the support frame 21, and the top frame 22, the installation assembly makes it easy to replace any damaged component, thereby reducing the overall usage cost and improving the practicality of the device.
[0024] Please see Figure 1 - Figure 3 In this embodiment, several first hollow slots 23 are provided, and these first hollow slots 23 are arranged in a honeycomb pattern on the support frame 21 to reduce the consumption of raw materials, improve the efficiency of printing operations, and enhance the practicality of the device. Several second hollow slots 24 are provided, and these second hollow slots 24 are arranged in a honeycomb pattern on the top frame 22 at positions corresponding to the first hollow slots 23 to reduce the consumption of raw materials, improve the efficiency of printing operations, and enhance the practicality of the device. A protrusion 25 is fixedly connected to one side of the support frame 21. Through the honeycomb-shaped first hollow slots 23 and second hollow slots 24 on the support frame 21 and the top frame 22, the consumption of raw materials during the printing process is reduced, production costs are lowered, and the time required for printing operations is reduced, thereby improving production efficiency and enhancing the overall practicality.
[0025] Please see Figure 4 - Figure 5In this embodiment, the mounting assembly includes a first through hole 31 on the support frame 21, a second through hole 32 on the top frame 22, a third through hole 35 on the base frame 1, a mounting bolt 33 disposed inside the first through hole 31, and a mounting nut 34 disposed inside the base frame 1. The mounting bolt 33 is disposed inside the second through hole 32, the third through hole 35, and the top frame 22. The mounting nut 34 is threaded to the outside of the mounting bolt 33. By mounting the base frame 1, the support frame 21, and the top frame 22, it is easy to replace any damaged component, thereby reducing the overall operating cost and improving the practicality of the device. Four sets of the first through hole 31, the second through hole 32, and the third through hole 35 are provided, arranged in a specific order. The secondary distribution on the support frame 21, top frame 22, and base frame 1 facilitates the insertion of mounting bolts 33, thereby facilitating the installation and fixation of the base frame 1, support frame 21, and top frame 22, improving overall support and stability. The top frame 22 has corresponding storage slots for the mounting bolts 33, allowing them to be easily stored during installation, thus enhancing usability and practicality. Similarly, the base frame 1 has corresponding storage slots for the mounting nuts 34, allowing them to be easily stored during installation, further improving usability and practicality.
[0026] During operation, the base frame 1 is made of polylactic acid (PLA). PLA is relatively hard and does not easily warp or deform during printing, thus meeting the support requirements for denture printing. The support frame 21 is made of photosensitive resin. Photosensitive resin has high printing precision and can form a fine support structure. Its surface smoothness helps reduce damage to the denture surface. The top frame 22 is made of acrylonitrile-butadiene-styrene copolymer. Styrene copolymers have good chemical corrosion resistance and are relatively stable in the oral cavity environment. By placing the support frame 21 on top of the base frame 1, the overall support and practicality are improved. Then, the top frame 22 is placed on top of the support frame 21. The mounting nut 34 is placed inside the storage groove of the base frame 1. Then, the mounting bolt 33 is passed through the second through hole 32 of the top frame 22, the first through hole 31 of the support frame 21, and the third through hole 35 of the base frame 1, and screwed in. The mounting nut 34 is threaded to the outside of the mounting bolt 33, thus fixing the base frame 1, support frame 21, and top frame 22. This allows for individual replacement of any one of the base frame 1, support frame 21, or top frame 22 if any one of them is damaged, avoiding the need to replace the entire structure when damaged, reducing usage costs. Furthermore, the first hollow groove 23 distributed on one side of the support frame 21 and the second hollow groove 24 distributed at the corresponding position of the first hollow groove 23 on the top frame 22 reduce the consumption of raw materials during printing and reduce the time required for printing operations.
[0027] Through the above steps, the first hollow groove 23 and the second hollow groove 24 distributed in a honeycomb pattern on the support frame 21 and the top frame 22 reduce the amount of raw materials used and lower the production cost while ensuring the support strength. In addition, the amount of raw materials required to fill during the printing process is reduced, and the printing time is shortened accordingly, thereby speeding up the overall production process. This solves the problem that solid structures not only consume a lot of raw materials during the printing process, but also reduce production efficiency.
