[0011] In order to prevent the fixing member from rubbing against the two racks, as a preferred guide rail structure for a 3D printer mobile nozzle of the utility model, the teeth of the two racks face in opposite directions.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the utility model is used, the two motors are in operation, and the output ends of the two motors respectively drive the two gears to rotate, and the two gears cooperate with the two racks to drive the fixed part to move along the X and Y axes to print a preset pattern. Since the two racks are staggered up and down, it is possible to prevent the two racks from interfering with each other and affecting the movement of the fixed part along the X and Y axes.
