[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, uses powdered metal or plastic and other bondable materials, and constructs objects by printing layer by layer. Digital twins integrate multi-physics, multi-scale, multi-domain, and multi-disciplinary attributes, and have the characteristics of real-time synchronization, faithful mapping, and high fidelity.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Specific implementation method 1: Please refer to Figure 1-7 The present invention provides a technical solution: a twin simulation product 3D printing device, comprising:

[0037] The casing 1 has a front and rear side panel provided with a viewing window 11, and a conveyor belt 22 is installed on the bottom panel 12 of the casing 1;

[0038] The printing platform 2 is fixed on the top surface of the conveyor belt 22, and a turntable 21 is placed on the top surface of the printing platform 2;

[0040] The slider 4 is mounted on the second guide rod 41. Both ends of the second guide rod 41 are fixedly connected to the lifting block 3. The slider 4 is connected to the rack 42 through a driving member.

[0041] The printing nozzle 5 includes a feeding section 51 and a melting section 52. The bottom end of the feeding section 51 passes through the fixed plate 6, the top end of the feeding section 51 passes through the slider 4, and the melting section 52 is placed on the top surface of the fixed plate 6;

[0042] A fixing plate 6, an extension plate 62 is welded to the middle of the bottom surface of the fixing plate 6, a scraper 63 is installed on the right side surface of the extension plate 62, and a semiconductor chip 61 is embedded in the left part of the bottom surface of the fixing plate 6;

[0043] The screed plate 7 is clamped at the front and rear ends of the extension plate 62. A limit block 71 is fixed on the outer side of the screed plate 7. A plug rod 73 is inserted into the limit block 71. The bottom end of the plug rod 73 is connected to a roller 72.

[0044] The rotating member 8 has two connecting rods 81 inserted therein. One end of the connecting rod 81 passes through the leveling plate 7 and is connected to the transmission gear 82. The connecting rod 81 is rotatably connected to the inserting rod 73.

[0045] When using the twin simulation product 3D printing device, one end of the filament is inserted into the melting section 52, and the feeding mechanism pushes the filament into the melting section 52. The feeding mechanism is not shown in the figure. The melting section 52 is heated to melt the filament, and the molten filament enters the feeding section 51 through spiral conveying. After the filament in the feeding section 51 is fully mixed, it is sprayed out from the discharge port 53, and the sprayed filament is deposited on the turntable 21. The leveling plate 7 and the scraper 63 are disassembled components and are not installed in the initial stage of printing. When the printed layer height meets the conditions, such as when the number of stacked layers is greater than five layers, the leveling plate 7 and the scraper 63 are installed to the corresponding positions. At this time, the filament sprayed out of the discharge port 53 is dispersed to both sides by the scraper 63, and a V-shaped groove is formed in the middle of the filament layer. After the filaments on both sides are smoothed by the leveling plate 7, they are quickly cooled and solidified, which is convenient for the deposition of the next layer of filaments, and the filaments sprayed out of the next layer fall into the V-shaped groove to prevent outward flow.

The second guide rod 41 and the rack 42 are horizontally connected between the lifting blocks 3 on the left and right sides. The screw 31 passes through the bottom plate 12 to connect to the motor. The rotation of the screw 31 causes the lifting block to perform a linear sliding motion. The screw 31 and the lifting block 3 are used to adjust the height of the print head 5. A motor is installed inside the slider 4. A gear is installed on the driving shaft of the motor. The gear is meshed with the rack 42.

[0049] Specific embodiment five: This embodiment is a further limitation of specific embodiment one, the cross-sections of the fixed plate 6 and the extension plate 62 are T-shaped, the width of the extension plate 62 is greater than that of the fixed plate 6, and the portion of the extension plate 62 that exceeds the fixed plate 6 is inserted with a limiting plate, the bottom surface of the extension plate 62 is higher than the bottom surface of the discharge port 53 and higher than the bottom surface of the scraper 63, a slot is formed between the limiting plates, and the limiting plates prevent the leveling plate 7 from deflecting.

[0050] Specific implementation method 6: This implementation method is a further limitation of specific implementation method 5. Figure 2 , Figure 3 and Figure 7 The bottom of the scraper 63 is V-shaped, and a row of paddles 64 are welded and fixed on the left side of the scraper 63.

[0052] Specific embodiment eight: This embodiment is a further limitation of specific embodiment one. The heating surface of the semiconductor chip 61 faces upward and the cooling surface faces downward. The semiconductor chip 61 is located directly below the molten material section 52. After the semiconductor chip 61 is connected to the current, the top surface temperature rises to provide heat for the molten material section 52, and the bottom surface temperature drops to provide cold air for the cooling consumables, thereby enhancing the cooling effect.

The rotating member 8 rotates to accelerate the air flow, so that the cold air under the semiconductor wafer 61 can fully contact the consumables, thereby accelerating the cooling and solidification speed and facilitating the deposition of the next layer of consumables. One end of the connecting rod 81 inserted into the rotating member 8 is consistent with the pattern of the inner wall of the rotating member 8. As the distance between the screed plates 7 increases, the depth of the connecting rod 81 inserted into the rotating member 8 decreases to adapt to the spacing adjustment.
