Patent ID: 6882895

Claim:
A method for manufacturing a product having locally specific properties, the geometric form of which is described by a collection of polygonal basic figures, in particular in STL (structural triangulation language), the method comprises the following steps: selecting from the collection of polygonal basic figures a subset of basic figures describing a coherent part of a surface of the product, the basic figures in the subset being selected automatically by selecting basic figures that are always adjacent to at least one previously selected basic figure from the surface part, so that the part of the surface defined by the selected basic figures is coherent, after the selecting step, assigning to the subset at least one specific property, which during the manufacture of the product is to be given to the part thereof that comprises said coherent part of the surface, optionally repeating the above process steps for other coherent part of the surface to be selected, and manufacturing the product on the basis of the then obtained model information by means of a technique adding material in layers or in a die molding process, which includes giving the associated specific property during the building up in layers of at least the part of the product that comprises the coherent part of the surface or during the injection molding.
