摘要： In a process for producing three-dimensional objects by applying and solidifying layers of a powdery material (7), material shrinkage during solidification causes the following layers to become thicker and thicker, so that only an insufficient solidification of said layers and of the previous layers is still possible. In order to solve this problem, once one layer (19) is solidified, at least one additional layer (21) is applied on the solidified spots of layer (19) and solidified at the same spots as layer (19). The thickness of the additional layer (21) substantially corresponds to the shrinkage of layer (19). The position of the support (3) upon which the layers are applied remains unchanged.
