Abstract:
1. A method for making products, by freeform sintering and/or melting, in which the products are fabricated layer by layer from a material that is applied layer by layer by means of a computer-controlled high-energy beam, wherein the beam irradiates predetermined positions of a material a plurality of m times in each case, where m is a whole integer greater than 1, wherein each of said positions is initially heated during the first irradiation to a temperature below the melting point (T melt ) of the material and during the m-th irradiation to a temperature above said melting point (T melt ) and is completely melted over the entire thickness of the layer in such a way that the material fuses at said position to a layer thereunder.
