Abstract: The device comprises an applicator surface assembly (20) having an element (22) having an application surface, a ceramic slurry supply assembly (30) having a ceramic slurry supply unit and a blade unit, and a starting surface assembly (40) having an element with a starting surface. The blade unit is moved in to the application surface parallel in direction from an initial position into an end position. The ceramic slurry supply unit is adapted in the direction of displacement of the blade unit before applying a predetermined quantity of ceramic slurry on to the application surface. The device comprises an applicator surface assembly (20) having an element (22) having an application surface, a ceramic slurry supply assembly (30) having a ceramic slurry supply unit and a blade unit, and a starting surface assembly (40) having an element with a starting surface. The blade unit is moved in to the application surface parallel in direction from an initial position into an end position. The ceramic slurry supply unit is adapted in the direction of displacement of the blade unit before applying a predetermined quantity of ceramic slurry on to the application surface to form a ceramic slurry layer. The predetermined quantity of ceramic slurry is determined during displacement of the blade unit from the initial position into the end position. The blade unit is further returned from the end position to the initial position. The starting surface element and the application surface element are displaceable relative to one another. The blade unit is arranged above the starting surface in the initial position. The ceramic slurry supply unit applies at a part of the predetermined quantity of ceramic slurry to the starting surface. The starting surface assembly is associated with a cleaning device for cleaning the starting surface. The starting surface element is made of an open-pore plastic material. The apparatus further comprises a further cleaning device for cleaning the blade unit, a discharge surface assembly having an element with a discharge surface, a side surface assembly having a side surface element with a side surface, a laser unit (70), a control unit for controlling the operation of the application surface assembly, starting surface assembly, discharge surface assembly, side surface assembly, ceramic slurry supply assembly and/or laser unit, and a drying unit. The blade unit is transferred into a cleaning position during returning of the blade unit. The starting surface element and the application surface element are disposed so that the starting surface and the application surface are arranged at the same height at start of manufacturing of a ceramic body. The discharge surface assembly is arranged on the starting surface element facing away from the application surface element. The blade unit, in the end position, is disposed above the discharge surface. The side surface assembly is laterally arranged to the application surface assembly. A surface normal of the discharge surface and the side surface is parallel to a surface normal of the application surface. The discharge surface element and/or the side surface element are disposed so that the discharge surface and / or the side surface are arranged at same height of the application surface and the starting surface at start of manufacturing of a ceramic body. The discharge surface element and the side surface element are displaceable relative to the application surface element. The discharge surface assembly is associated with a cleaning device for cleaning the discharge surface. The laser unit is adapted to mold predetermined sections of the coated ceramic slurry layer by the emitted laser beam. The control unit controls the application surface assembly such that the applicator surface element is lowered by the height of the applied ceramic slurry layer. An independent claim is included for a starting surface assembly.
