Disclosed is a 3D printer for construction projects. The 3D printer comprises a Y-axis sliding rail (12), an X-axis sliding rail (13) and a Z-axis sliding rail (14). The X-axis sliding rail (13) is slidably connected to the Y-axis sliding rail (12). The Y-axis sliding rail (12) is slidably connected to the Z-axis sliding rail (14) through a pulley b (15). The pulley b (15) is provided with a locking device (16) used for locking and locating the Y-axis sliding rail (12) and the Z-axis sliding rail (14). A telescopic printing mechanism is slidably connected to the X-axis sliding rail (13) through a pulley a (7). A carriage (6) of the printer completes instructions in place of the Z-axis, changing the movement system for the Z-axis. With accurate height control, the carriage avoids problems such as unbalance in operation caused by a track offset and Y-axis compression when the printer is working.

The telescopic printing mechanism comprises a print head. The print head is provided with a feeding motor, and the feeding motor is connected with a screw shaft, and the screw shaft extends into the printing head.

The top of the print head is connected with a carriage, the screw frame is provided with a screw seat and a screw, the screw is externally threaded, the nut is matched with the external thread of the screw, the silk mother is fixed on the silk frame, and the silk frame and the branch are supported. The frame is fixedly connected, the screw is connected to the lifting motor through a coupling, and the bracket is fixed on the trolley a, and the carriage is slidably connected with the bracket.

The silk mother is a metal mother.

The silk mother is a copper silk mother.

The screw is a metal screw.

The locking device is located on the trolley b, and the Y-axis slide rail and the Z-axis slide rail are locked and locked by the trolley b.

The telescopic printing mechanism is located on the trolley a, and is slidably coupled to the X-axis slide rail by the trolley a.

The invention has the beneficial effects of changing the movement system of the Z-axis and realizing the movement process of the Z-axis by the up-and-down movement of the intermediate print head itself. In the printing process, the X-axis and the Y-axis are first raised to an appropriate height and locked, and then The print head moves to the lowermost end, and the printing height of the print head is controlled by the lifting motor provided by the printing mechanism. The Z-axis and the Y-axis are locked by the locking device, and the carriage replaces the Z-axis to complete various commands, and the Z-axis moving system is changed. The height is controlled accurately, which avoids the track deviation caused by the printer during operation and the unbalanced work caused by the Y-axis compression.
