[0040] Refer to Figure 8 , the lifting and sliding assembly 7 includes a lifting and sliding track 71, a lifting seat 72, a lifting cylinder 73, and a lifting rod 74.

[0042] The specific implementation principle of the embodiment of the present application is as follows: when the 3D printer needs to be used for printing, the material bin 41 is removed from the bottom end of the dual-axis motor 42, printing material is added into the material bin 41, the rotating shaft of the dual-axis motor 42 rotates to drive the screw rod 43 to rotate, and the screw rod 43 conveys the printing material in the material bin 41 to the print head 4 and discharges it, so that the discharged printing material gradually forms on the printing platform 3. The rotating shaft of the driving motor rotates to drive the lateral sliding track 82 and the printing platform 3 to make a horizontal lateral sliding movement through the second conveyor belt 84, so that the print head 4 prints different lateral positions of the product. When the print head 4 is printing, the dual-axis motor 42 drives the lead screw 55 to rotate, thereby driving the indicating block 54 and the sliding seat 53 to make a lifting sliding movement along the indicating guide rail 52 through the lead screw 55. The amount of remaining printing material in the material bin 41 can be understood through the position of the indicating block 54, so that printing material can be added into the material bin 41 in time.

[0043] As the product on the printing platform 3 gradually increases in height, the telescopic rod of the lifting cylinder 73 extends to drive the longitudinal sliding assembly 6 and the print head 4 to rise along the lifting sliding track 71, so as to adapt to the increase in height of the product on the printing platform 3. When the horizontal longitudinal position of the print head 4 needs to be adjusted, the rotating shaft of the rotating motor 641 rotates to drive the first pulley 642 to rotate, and drives the print head 4 and the indicating assembly 5 to make a horizontal longitudinal sliding movement during the transmission of the first conveyor belt 644, so as to adjust the horizontal longitudinal position of the printed position of the product. The position is adjusted through the lateral sliding assembly 8, the lifting sliding assembly 7 and the longitudinal sliding assembly 6, so that appropriate distances are maintained between different positions of the print head 4 and the printing platform 3.
