    摘要: that precede a reference layer (4) in the succession; defining a mask area (9) corresponding to the logical conjunction of the geometric representations of the reference layer (4) and of the selected layers (2) reproduced on the plane of the reference layer (4); exposing the liquid material to the predefined radiation (6) in the mask area (9). According to the method, before defining the mask area (9) the geometric representations of the selected layers (2) are modified in order to extend them with corresponding additional portions (2a) that project with respect to the geometric representations of the corresponding layers (2) as configured before the modification, wherein the additional portions (2a) are defined to compensate for the reduced solidifying effect of the predefined radiation (6) on the liquid material due to its penetration in the liquid material down to the depths corresponding to the layers (2), so that the outline of the portion of the three-dimensional object (10) obtained following the solidification of the group of layers approximates more precisely the outline (11) of the three-dimensional object (10).
