The invention relates to a method for making metallic and/or non-metallic
products 2, in particular dental products, by freeform sintering and/or
melting, in which the products 2 are fabricated layer by layer from a
material 5 that is applied layer by layer by means of a
computer-controlled high-energy beam 7, in particular a laser or electron
beam. In order to reduce production times, beam 7 irradiates
predetermined positions P1 to P6 of a layer of a material 5 a plurality
of time, namely m times, where m is a whole integer greater than 1. Each
of said positions P1 to P6 is initially heated during the first
irradiation to a temperature below the melting point T.sub.melt of the
material 5, and during the mth irradiation to a temperature above said
melting point and is completely melted over the entire thickness of the
layer in such a way that the material (5) fuses at said position to the
layer thereunder. The invention also relates to an apparatus for
performing said method.
