The screw 37 is fixedly connected to the back of the first transmission disk 34 and the second transmission disk 36. The back of the screw 37 is movably connected to the surface of the 3D printer body 1 through a bearing. The surface of the screw 37 is threadedly connected to the inner wall of the error detector 31.

[0028] refer to Figure 4 The output end of the motor 33 is fixedly connected to a heat dissipation component 4. The heat dissipation component 4 includes a gear 41, which is fixedly connected to the output end of the motor 33. A rotating rod 42 is meshed at the bottom of the gear 41. The left side of the rotating rod 42 is movably connected to the inner wall of the protective shell 32 through a bearing. A cooling fan 43 is fixedly connected to the right side of the rotating rod 42.

[0029] As a technical optimization of this utility model, the heat dissipation component 4 can be used to dissipate heat inside the protective shell 32, thereby improving the service life of the internal parts of the protective shell 32.

[0030] refer to Figure 4 The bottom of the motor 33 is fixedly connected to a fixing plate 5, and the bottom of the fixing plate 5 is fixedly connected to the bottom of the inner wall of the protective shell 32.

[0031] As a technical optimization of this utility model, the fixed plate 5 can provide auxiliary support for the motor 33, preventing the motor 33 from being unstable due to insufficient single-point support.

[0032] refer to Figure 2 A guide rod 6 is fixedly connected to the front of the 3D printer body 1. The guide rod 6 passes through the error detector 31 and is slidably connected to the error detector 31.

[0033] As a technical optimization of this utility model, the guide rod 6 can limit the error detector 31 and prevent the error detector 31 from rotating when it moves.

[0038] The working principle and usage process of this utility model are as follows: Before using the 3D printer body 1, the user needs to perform a precise error detection step on the work platform 2. After starting the motor 33, the output end of the motor 33 will drive the first transmission disk 34 to start rotating. This rotational power is efficiently transmitted to the second transmission disk 36 through the belt 35, causing the two to work together and further drive the screw 37 to rotate stably. The screw 37 and the error detector 31 are connected by a thread, which allows the error detector 31 to move back and forth precisely along the surface of the screw 37. This design not only makes it easy for the error detector 31 to adjust its position according to actual needs, but also ensures the flatness of the work platform 2. The system performs meticulous and comprehensive error detection. Once an error is detected, the system will immediately alert the operator, allowing them to quickly take corrective measures to ensure print quality. At the same time, during operation, the output end of motor 33 will drive gear 41 to rotate. The precise meshing between gear 41 and rotating rod 42 ensures the smooth rotation of rotating rod 42, which in turn drives cooling fan 43 to start rotating. The efficient operation of cooling fan 43, through the heat dissipation mesh equipped on the protective shell 32, effectively dissipates the generated heat, ensuring the stable operation of the entire system. This series of interconnected designs not only improves the ease of operation and printing accuracy of the 3D printer, but also greatly enhances its working efficiency and stability.

[0039] In summary, this 3D printer error detection mechanism, by adding the functionality of automatically detecting errors on the work platform, automates the error detection process, preventing the need for operators to check the flatness of the work platform before using the 3D printer. This solves the problem of requiring operators to check the flatness of the work platform before using the 3D printer.
