[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention realizes the printing of the building model by combining the three-dimensional moving part and the 3D printing head, and prints the building model on the material support plate at the top. When the building model is printed, it cannot be removed from the material support plate immediately because the building model is not completely solidified.

At this time, the end of the positioning column away from the limit end plate will be detached from the inside of the positioning hole at the top. After that, the material replacement component can be driven to rotate by the positioning component to rotate the printed model at the top to the bottom. Since the track plug-in column 1 is plugged into the inside of the irregular annular track 1, and the track plug-in column 2 is plugged into the inside of the irregular annular track 2, during the overall rotation of the material replacement component, the square support plate will always remain horizontal to avoid the tilt of the model. The model at the bottom will be cooled by the cooling fan, so that it will be quickly solidified and easy to unload.

[0016] 2. While the model on the material tray at the bottom is dissipating heat, the model on the material tray at the top can continue to be printed, which greatly improves the printing efficiency. In addition, by starting the execution motor, the vertical axis and the material tray can be driven to rotate, so that the model on the material tray rotates. At this time, the cooling fan performs all-round heat dissipation on the rotating model on the material tray, which greatly improves the solidification efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
