Abstract
A method is presented that makes possible the labelling of powders that can be applied as building material in a layer-additive manufacturing method such as a selective laser sintering method. To this effect the powder is mixed with at least one salt of a metal of the rare earths, wherein the salt has the property that it shows a luminescence when being irradiated with photons having a wavelength outside of the visible spectrum or with particle radiation. Thereby, parts that have been manufactured by means of the layer-additive manufacturing method can be identified with regard to the manufacturer, the place of manufacture or the manufacture date.
