Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figures 1-6 As shown, this utility model provides a high-efficiency metal 3D printer, including an outer frame 1 and a printing frame 9. A protective door 2 is rotatably mounted on the outer surface of the outer frame 1 via a hinge. A control panel 3 is provided on the outer surface of the protective door 2. A mounting frame 4 is fixedly mounted on the inner surface of the outer frame 1. A fixing seat 5 is fixedly mounted on the outer surface of the mounting frame 4. A first rotating wheel 6 is rotatably mounted on the outer surface of the fixing seat 5. A print head 10 is fixedly mounted on the outer surface of the printing frame 9. A first motor 11 is fixedly mounted on the outer surface of the mounting frame 4. A second rotating wheel 12 is fixedly mounted on the output shaft of the motor. A moving component 13 and a slide bar 14 are fixedly mounted on the outer surface of the mounting frame 4. A moving frame 15 is provided on the outer surface of the mounting frame 4.

[0031] Specifically, the outer surfaces of the first roller 6 and the second roller 12 are provided with connecting belts 7, and the outer surfaces of the connecting belts 7 are provided with connecting blocks 8. The connecting blocks 8 are fixedly installed with the print frame 9. The advantage is that, through the cooperation of the first roller 6, the second roller 12 and the connecting belts 7, the long-distance movement of the print frame 9 can be stably realized, and the moving speed and position of the print frame 9 can be controlled more precisely, ensuring that the print head 10 can accurately reach the target printing position in the horizontal direction. This is conducive to improving the printing accuracy and quality and reducing printing defects caused by the position deviation of the print head 10.

[0032] Specifically, the moving component 13 includes a mounting base 1301. A second motor 1302 is fixedly mounted on the outer surface of the mounting base 1301. A lead screw 1303 is fixedly mounted on the output shaft of the second motor 1302. A sliding block 1304 and a moving platform 1305 are threadedly connected to the outer surface of the lead screw 1303. A moving seat 1306 is fixedly mounted on the outer surface of the moving platform 1305. The moving seat 1306 and the slide rod 14 are slidably connected. The advantage is that, through the design of the moving component 13, the transmission method of the motor driving the lead screw 1303 can achieve high-precision positioning control of the print head 10 in the horizontal direction, which can effectively improve the accuracy of the printed layer thickness. Furthermore, the sliding connection between the slide rod 14 and the moving seat 1306 provides a stable guide for the moving platform 1305. The moving platform 1305 can only move smoothly in the vertical direction without lateral deviation or shaking, which further enhances the stability and reliability of the print head 10 during vertical movement and reduces printing errors caused by unstable vertical movement.

[0033] Specifically, a pulley 16 is rotatably mounted on the outer surface of the movable frame 15. The pulley 16 is slidably connected to the mounting frame 4. The advantage is that the pulley 16 greatly reduces the friction between the movable frame 15 and the mounting frame 4, making the printing frame 9 move more smoothly during horizontal movement, thus improving the operating efficiency and service life of the equipment.

[0034] Example 2: Figures 2-6 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the moving component 13 is located directly below the print head 10, and the print frame 9 and the moving frame 15 are slidably connected. The advantage of this slidable connection between the print frame 9 and the moving frame 15 is that while ensuring that the print frame 9 can move freely in the horizontal direction, it also provides stable support and guidance for the vertical movement of the print head 10. This makes the movement of the print head 10 in three-dimensional space more coordinated and precise, which is conducive to improving the stability and reliability of the entire 3D printing process and reducing the generation of printing defects.

[0036] Specifically, motor 11 and moving component 13 are electrically connected to control panel 3. Moving component 13 is located on the inner surface of outer frame 1. The advantage is that the start and stop of motor 11 and motor 2 1302 can be flexibly adjusted by control panel 3 according to different printing tasks and material characteristics, which is convenient for operators.

[0037] Specifically, the fixed base 5, rotating wheel 1 6, connecting belt 7, printing frame 9, print head 10, motor 11, rotating wheel 2 12, moving component 13, slide bar 14, moving frame 15, and pulley 16 are arranged in two identical sets. The two sets of fixed base 5, rotating wheel 1 6, connecting belt 7, printing frame 9, print head 10, motor 11, rotating wheel 2 12, moving component 13, slide bar 14, moving frame 15, and pulley 16 are symmetrically distributed about the center line of the outer frame 1. The advantage is that the arrangement of two sets of identical components increases the printing capacity and flexibility of the equipment, enabling multiple printing modes, such as single-head printing, dual-head synchronous printing, or dual-head asynchronous printing. The appropriate printing mode can be selected according to different printing needs and metal material characteristics, improving the working efficiency of the equipment and its adaptability to different printing tasks. It has obvious advantages in large-scale metal 3D printing production.

[0038] Working Principle: During use, the cooperation of roller 1 (6), roller 2 (12), and connecting belt 7 enables stable long-distance movement of the print carriage 9. It also allows for precise control of the print carriage 9's movement speed and position, ensuring the print head 10 accurately reaches the target printing position in the horizontal direction. This improves printing accuracy and quality, reducing printing defects caused by print head 10 positional deviations. The design of the moving component 13, using a motor-driven lead screw 1303, achieves high-precision horizontal positioning control of the print head 10, effectively improving the accuracy of the printed layer thickness. Furthermore, the sliding connection between the slide bar 14 and the moving base 1306 provides stable guidance for the moving platform 1305, ensuring smooth vertical movement without lateral deviation or wobbling. This further enhances the stability and reliability of the print head 10 during vertical movement, reducing printing errors caused by unstable vertical movement. The pulley 16 significantly reduces the distance between the moving frame 15 and the mounting frame 4. Friction makes the horizontal movement of the printing frame 9 smoother, improving the operating efficiency and service life of the equipment. The sliding connection between the printing frame 9 and the moving frame 15 ensures that the printing frame 9 can move freely in the horizontal direction, while also providing stable support and guidance for the vertical movement of the print head 10. This makes the movement of the print head 10 in three-dimensional space more coordinated and precise, which is conducive to improving the stability and reliability of the entire 3D printing process and reducing the generation of printing defects. The control panel 3 can flexibly adjust the start and stop of motor 11 and motor 2 1302 according to different printing tasks and material characteristics, which is convenient for operators. The setting of two sets of identical components increases the printing capacity and flexibility of the equipment, and can realize multiple printing modes, such as single-head printing, dual-head synchronous printing, or dual-head asynchronous printing. It can select the appropriate printing mode according to different printing needs and metal material characteristics, improving the working efficiency of the equipment and its adaptability to different printing tasks. It has obvious advantages in large-scale metal 3D printing production.
