3D printing equipment

The invention discloses 3D printing equipment. The 3D printing equipment comprises a storage device, a peristaltic pump, an extrusion head, an ultraviolet light curing device, a printing tray, an X-axis motion mechanism, a Y-axis motion mechanism, a Z-axis motion mechanism and a controller. A liquid photosensitive material is contained in the storage device. One end of the peristaltic pump is connected with the storage device through a pipeline, the other end of the peristaltic pump is connected with the extrusion head through a pipeline, the ultraviolet light curing device is connected with the extrusion head, the printing tray is located below the extrusion head, and the controller controls the peristaltic pump, the ultraviolet light curing device, the X-axis motion mechanism, the Y-axis motion mechanism and the Z-axis motion mechanism. Through the cooperation of the peristaltic pump and the extrusion head, liquid printing materials are conveyed and printed, and printing accuracy is high. The ultraviolet light curing device and the extrusion head are fixed together and kept synchronous in the operating process, and rapid curing is achieved while printing is conducted.
