Zusammenfassung:	The invention provides a cylinder body sealing device for additive manufacturing. The cylinder body sealing device comprises a movable part which is arranged in a gap between a working chamber and a cylinder body; the bottom of the movable part is movably connected with the top end of the cylinder body, the movable part moves along a plumb line relative to the cylinder body, the movable part moves towards the working cavity, the top face of the movable part abuts against and is attached to the bottom face of the working cavity to form a sealing structure, and the working cavity communicates with the cylinder body. Or the movable part moves away from the working chamber and enables the working chamber and the cylinder body to be disconnected; the relative height of the cylinder body and the working cavity is kept unchanged, the cylinder body and the working cavity are communicated in a sealed mode through vertical lifting of the movable part, and the problem that when the cylinder body with great quality is ja
