Abstract
A recoating unit for equipping and/or retrofitting a device for producing a three-dimensional object by means of selectively solidifying, layer by layer, of a building material in powder form. The recoating unit is configured, depending on its movement in the first direction or in its opposite direction, to receive building material in that chamber that is the trailing chamber in the respective direction of movement and to spread the building material received in the respective trailing chamber to a uniform layer by means of the respective trailing recoating element.
