Abstract
The present invention relates to a recoating device that performs the function of evenly applying powder in a powder bed-type 3D printer and a 3D printer including the same. The recoating device of the present invention is formed to include a leveling blade that generates a flow of powder in a direction perpendicular to a moving direction of the recoating device, thereby evenly leveling powder even if the discharge amount of powder is uneven depending on a position at the front of the recoating device.
