A drive motor 103 is fixedly installed at the front end of the unit. A gear component 104 is fixedly installed on the top shaft of the drive motor 103. A gear platform 105 is rotatably connected to the top middle position of the advancing frame 102. The front end of the gear platform 105 meshes with the rear end of the gear component 104 for transmission. The top two sides of the base 1 are fixedly connected to the bottom two sides of the adjusting frame 2. A lifting motor 201 is fixedly installed at the lower left side of the adjusting frame 2. The shaft of the lifting motor 201 is fixedly connected to the bottom of the lifting screw 202.

[0027] The adjusting frame 2 has a sliding connection to the middle of its interior, and a threaded hole on its left side. The lifting screw 202 passes through the threaded hole of the lifting frame 203. A horizontal belt motor 204 is fixedly installed at the rear left side of the lifting frame 203.

[0028] When using:

[0029] The 3D printed product to be repaired is placed on top of the gear table 105. According to the damaged position of the product, the advance motor 101 is started. Its shaft drives the advance frame 102 to slide back and forth along the base 1 through the thread drive, and the product is moved to the front end position below the repair print head 208.

[0030] Start the lifting motor 201. The shaft of the lifting motor 201 drives the lifting screw 202 to rotate. Through the threaded engagement, the lifting frame 203 slides up and down along the adjusting frame 2, so that the repair print head 208 maintains the optimal repair distance of 5-10mm with the product surface.

[0031] Start the horizontal belt motor 204, which drives the angle motor group 205 to move horizontally along the lifting frame 203 via belt drive, so as to achieve precise positioning of the repair print head 208 in the X-axis direction.
