A coating unit (9) for an arrangement for producing moldings (2) made of building material (3) by using radiation energy, especially for laser or stereo lithography installations, comprises a horizontally movable blade unit (10) with at least one coating blade (13), for transporting the material from a storage vessel (11). A coating unit (9) for an arrangement for producing moldings (2) made of building material (3) by using radiation energy, especially for laser or stereo lithography installations, comprises a horizontally movable blade unit (10) with at least one coating blade (13), for transporting the material from a storage vessel (11). The building material is applied uniformly to the building surface using the lower blade edge. The blade unit has at least one shearing blade which can be moved over the surface. Each blade has a number of shear blades associated with it and the height of the shear blades can be adjusted relative to the coating blade height. |
