The invention discloses a device and method for manufacturing a plate with a directional structure. The device for manufacturing the plate with the directional structure comprises a material storing system with the bottom end provided with a material outlet, a three-dimensional moving platform located below the material storage system and a cooling platform arranged on the three-dimensional movingplatform and used for conducting laying casting on materials stored in the material storing system, wherein one side or two sides of the material storing system is or are provided with a secondary cooling device or secondary cooling devices. When the device is used for manufacturing the plate, after the material storing system processes the materials, the materials flow out through the material outlet, the three-dimensional moving platform is adjusted to move, the materials in the material storing system is spread in layers on the cooling platform, the materials are further cooled and rolledthrough the secondary cooling device, and then the plate can be obtained. According to the device for manufacturing the plate with the directional structure, through combination and cooperation of the material storing system, the three-dimensional moving platform and the secondary cooling device, the plate of the directionally solidified structure can be produced, ingredient distribution of the plate is uniform, and the mechanical property of the plate is stable; and meanwhile, the method for producing the plate by the adoption of the device is simple, high in operability, high in productionefficiency and capable of achieving continuous production and saves resources
