Abstract
A recoating unit () serves for equipping or retrofitting a device () for additive manufacturing of a three-dimensional object () by selectively solidifying a building material (), preferably a powder, layer by layer. The device () comprises a recoater () movable across a build area () for applying a layer () of the building material () within the build area () and a solidification device () for selectively solidifying the applied layer () at positions corresponding to a cross-section of the object () to be manufactured. The device () is formed and/or controlled to repeat the steps of applying and selectively solidifying until the object () is completed. The recoating unit () comprises at least two recoating rollers () spaced apart from each other in a first direction (B) and extending into a second direction transversely, preferably perpendicularly, to the first direction. At least one of the recoating rollers (), preferably both of the recoating rollers () are formed adjustable in a third direction perpendicular to the first direction and the second direction in the recoating unit ().
