摘要： A method of manufacturing an object (3) in a build area (22) by means of a successive layer-by-layer solidification of a building material in powder form (18) comprises the steps: a) applying a layer of the building material in powder form (18) having a predetermined thickness d2 onto a layer of the building material already previously applied which has been solidified in a region corresponding to a cross section of the object (3), wherein, for applying the building material (18), a recoater (5, 15) is moved in a direction (B) across the layer already previously applied, and b) selectively solidifying the building material (18) applied in step a) in a region corresponding to a cross section of the object (3), wherein, prior to the application of a layer, for a solidified region having a thickness d1 in the layer applied before, the maximum (MAX) of the product of the extension of this solidified region in movement direction (B) of the recoater (5) and the thickness d1 is determined and during the application of the layer in step a), at least an additional powder amount (P2) proportional to the value of the maximum (MAX) is additionally provided.
