Beschreibung
Zusammenfassung:	The invention provides a movable exhaust device of a large 3D printer, firstly, a 3D printer body is arranged and comprises a forming chamber, a forming surface for laser scanning is arranged in the forming chamber, an exhaust device body is erected on the forming surface, and the forming surface is equidistantly divided into a first scanning area and a second scanning area in the X-axis direction; the air exhaust device body comprises an X-axis mechanical module and an air exhaust assembly, the air exhaust assembly is driven by the X-axis mechanical module to move horizontally in the X-axis direction, the air exhaust assembly comprises an air exhaust area, and the air exhaust area moves to the position over the first scanning area or the position over the second scanning area along with the air exhaust assembly. Compared with the prior art, the movable air exhaust device is provided for a large 3D printer, the problem that the air exhaust efficiency above a large-area forming face is insufficient is solved,
