The forming platform enables the printing material to be light-cured on the upper surface of the forming platform so as to form a model by means of layer-by-layer molding. Since the release film is arranged above the forming platform, the release film does not need to bear the weight of the printing material and the printing model, and is not prone to deformation. When the forming platform moves away from the release film, the forming platform only applies a small tug force on the release film. When the release film needs to be replaced, the release film can be replaced by using the release film replacement device.
