Abstract
The invention relates to a method for manufacturing a product in layers, said method comprising the following steps: (a) applying a layer of a curable material, (b) selectively curing predetermined zones of the applied layer on the basis of geometrical data of the product, (c) repeating steps (a) and (b) until the geometry of the product has been created in the form of cured material and (d) removing the uncured material. According to the invention, a finish allowance, for example one with a wedge-shaped cross-section, is applied in steps (a) and (b), in one, two or more product sections in which an angle (α) between an axis perpendicular to the layers and at least one surface section of a contour of the product exceeds a predetermined value, to said surface section in such a way that the angle (β) between the axis perpendicular to the layers and the external surface in said product section does not exceed said predetermined value.
