Description

Technical Field

[0001] This utility model belongs to the field of experimental instrument technology, specifically relating to a photopolymerization 3D printer molding platform. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Currently, to meet the requirements of precision printing of complex structures, digital light processing 3D printing technology has been applied to the processing of polymer materials. Rapid prototyping, fine structure forming, reduction of printing defects, and improvement of mechanical properties are key factors driving the development of additive manufacturing technology. Based on data from digital 3D models, 3D printed objects are created layer by layer through computer-controlled compilation. Unlike traditional methods that require molds or photolithographic masks, digital light processing 3D printing can quickly transform computer-aided designs into complex 3D prototypes without wasting excess material.

[0004] Currently, some digital light processing 3D printers have fixed-size, non-disassembleable molding platforms. Even printing small samples requires a large amount of resin injection, especially for laboratory photopolymer 3D printers. Laboratory photopolymer 3D printers are typically used to develop new materials, but new material systems usually cannot be mass-produced during the development phase, thus requiring trial 3D printing with smaller quantities of material. Once the process matures, scale-up testing is needed to ensure its reliability. The inability to control sample size according to actual needs leads to waste when printing with new materials.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Currently, some digital light processing 3D printers have fixed-size, non-disassembleable molding platforms. Even printing small samples requires a large amount of resin injection, especially for laboratory photopolymer 3D printers. Laboratory photopolymer 3D printers are typically used to develop new materials, but new material systems usually cannot be mass-produced during the development phase, thus requiring trial 3D printing with smaller quantities of material. Once the process matures, scale-up testing is needed to ensure its reliability. The inability to control sample size according to actual needs leads to waste when printing with new materials.

[0026] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a photopolymerization 3D printer molding platform, such as... Figure 1 As shown, it includes a platform body, an embedded groove body 11, and a heating device; the platform body includes a platform base plate 2, and a first platform side plate 1 and a second platform side plate 12 are provided on the upper end of the platform base plate 2, and the first platform side plate 1 and the second platform side plate 12 are symmetrically arranged; an embedded groove 8 is provided on the embedded groove body 11, and a bracket handle 10 is provided on the side wall of the embedded groove body 11, and the end of the bracket handle 10 is in close contact with the inner wall of the first platform side plate 1.

[0027] Specifically, by cooperating with the platform body and the embedded groove body 11, samples of different sizes can be printed as needed. When printing large samples, the embedded groove body 11 can be removed for printing. When printing smaller samples, the embedded groove body 11 is installed on the platform body, so that the end of the bracket handle 10 is in close contact with the inner wall of the first platform side plate 1, and the bottom rubber strip 9 of the embedded groove body 11 is in close contact with the platform base plate 2, so that small-sized samples can be printed. This makes the utilization rate of printing materials higher and avoids material waste. The platform body and the embedded groove body 11 are connected by a snap-fit ​​method, which makes the overall installation and disassembly convenient and allows for quick switching, thereby improving printing efficiency.

[0028] The lower end of the first platform side plate 1 is fixedly connected to the platform base plate 2, the lower end of the second platform side plate 12 is fixedly connected to the platform base plate 2, and the side of the first platform side plate 1 and the side of the second platform side plate 12 are fixedly connected.

[0029] Specifically, the platform body consists of a platform base plate 2, a first platform side plate 1, and a second platform side plate 12. The platform body has a square structure. When in use, materials are injected from the top of the platform body to manufacture samples.

[0030] The inner wall surfaces of the first platform side plate 1 and the second platform side plate 12 are coated with polytetrafluoroethylene, and the outer wall surfaces are provided with grooves.

[0031] Specifically, the PTFE coating is non-stick, has a smooth surface, and does not easily adhere to other substances, effectively preventing materials from sticking to the side panel surface. It also has high-temperature resistance; the PTFE coating maintains stable performance in high-temperature environments, making it suitable for such conditions and preventing platform deformation when the material is heated.

[0032] The platform base plate 2 is a transparent quartz sheet, which has excellent high-temperature resistance and is suitable for high-temperature environments, facilitating observation of the sample's state during high-temperature processes. The platform body as a whole has high-temperature resistance properties and can be used for sample preparation through high-temperature material injection.

[0033] Specifically, the silicone heating pad 3 is embedded in the side wall groove and fits tightly against the side wall to heat the printing resin during the experiment.

[0034] The heating device includes a controller, heating element, temperature control knob 4, temperature controller 6, and digital temperature display 5. The controller is electrically connected to the heating element, temperature control knob 4, temperature controller 6, and digital temperature display 5; the heating element is embedded in the groove. The controller is a PLC controller and can be installed on the side panel.

[0035] Specifically, the heating element is equipped with a corresponding battery for power supply. The heating element generates heat to heat the platform body. The temperature of the platform body is monitored by the temperature controller 6 and fed back to the controller. The controller then transmits the temperature to the digital temperature display 5 for display. The operator can view the temperature and control the temperature by adjusting the temperature control knob 4. In other words, the heating device heats the material and effectively controls the heating temperature. The temperature of the material can be observed in real time and adjusted accordingly, thus improving the molding effect of the sample.

[0036] Several heating elements are spaced apart, and a digital temperature display 5 is installed at one end of each heating element. The heating elements and the digital temperature display 5 are electrically connected.

[0037] Specifically, the heating element is a silicone heating element 3. The silicone heating element 3 contains a socket for connecting a temperature controller 6, a digital temperature display 5, and a temperature control knob 4. The temperature controller 6 connects to the digital temperature display 5 via a wire connection socket, enabling real-time transmission of the printing resin's temperature data to the display, allowing operators to monitor the temperature in real time. Heating is achieved by laying the heating element, ensuring rapid and uniform heating while maintaining high safety, as the silicone acts as both a heat conductor and an insulator.

[0038] A temperature control knob 4 is provided at the other end of the heating element, and the temperature control knob 4 is electrically connected to the heating element.

[0039] Specifically, by rotating the temperature control knob 4, the target temperature can be set according to actual needs, and the temperature can be adjusted as needed.

[0040] The temperature controller 6 is installed at the upper end of the platform base plate 2. The temperature controller 6 is a high temperature resistant type.

[0041] Specifically, the temperature controller 6 typically uses a temperature sensor to sense the temperature of the environment or object, and then converts the temperature signal into an electrical signal. The controller compares this electrical signal with the set temperature value, and issues a control command based on the comparison result, adjusting the power or operating status of the heating or cooling equipment to maintain the temperature within the set range.

[0042] The bottom of the inner groove body 11 is covered with a rubber strip 9, and the rubber strip 9 and the inner groove body 11 are detachably connected.

[0043] Specifically, the sealing of the bottom of the inner groove body 11 and the platform base plate 2 is improved by covering the rubber strip 9, so as to prevent the material from leaking out from the bottom when manufacturing small-sized samples.

[0044] Several bracket handles 10 are spaced apart, and the bracket handles 10 and the embedded groove body 11 are fixedly connected.

[0045] Specifically, the dimensions of the embedded groove body 11 can be designed according to the required sample size. Multiple sizes of embedded groove bodies 11 can be set to suit the manufacture of samples of different sizes. Similarly, the dimensions of the support handle 10 also need to be adjusted to ensure that the end of the support handle 10 can be tightly attached to the inner wall of the first platform side plate 1. The area of ​​the embedded groove body 11 is 25%-80% of the area of ​​the inner groove of the platform body. Furthermore, the handle can be moved to facilitate insertion, fixation, and removal. The handle is connected to the embedded groove body 11 by screws. The screws can be rotated to move the handle a certain distance, thereby fixing it against the inner wall.

[0046] The second platform side plate 12 has a discharge port 7 on its outer wall surface.

[0047] Specifically, the discharge port 7 is connected to the interior of the platform body. A switch is installed at the discharge port 7. After printing is completed, the discharge port 7 is opened to rinse away any remaining material for subsequent use. The switch can be configured as a baffle. When in use, the baffle is inserted into the discharge port 7, and after completion, the baffle is removed to pour out the material.

[0048] This invention is easy to disassemble, making it more convenient to replace and clean the forming platform, and has a wider range of applications, suitable for printing samples of different sizes. Furthermore, it allows for quick switching of the embedded slot 8 body, resulting in higher utilization of printing materials and reducing waste.

[0049] Maintenance is convenient; after printing, simply open the discharge port 7 to rinse away any remaining resin material. This helps reduce the cost of printing experiments involving samples of different sizes using photopolymer 3D printing and improves the utilization rate of resin raw materials.

[0050] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
