The utility model relates to laser forming equipment for large-breadth additive manufacturing of a single galvanometer. The utility model belongs to the technical field of additive manufacturing, andrelates to an additive manufacturing device which comprises a point light source or a linear light source, a galvanometer, a lens, a forming bin, a forming base plate, a transmission mechanism and a fixing platform, the galvanometer or the forming bin can rotate around the center axis of the forming bin, and a scanning area of laser on a forming surface rotates relative to the forming surface; specifically, a rotating device capable of enabling the galvanometer to rotate around the central axis of the forming bin is installed at the bottom of the galvanometer, or a rotating assembly capable ofenabling the forming bin to rotate around the central axis of the forming bin is installed at the bottom of the forming bin. The single laser galvanometer is adopted, so that the forming area of thelaser forming equipment is
