A device for applying a thin layer of a powder on a support means () includes a device () for storing the powder, a screed () that includes a shoe () with a working surface, as well as a device () for guiding in translation in a direction of movement F. The shoe () is rotatable and includes a device () for inclining the to take at least two positions, the first in which the working surface is parallel to the support () for the layers to take up a predetermined volume of powder and a second in which this working surface is inclined at an angle &#x3b1; relative to the support.

Device for applying thin layers of a powder or pulverulent material and corresponding method

A succession of superposed digitized sections of an object are produced from a three-dimensional representation of the object. A powder or a mixture of powders is spread in the form of a fine layer and heated to a temperature close to solid phase sintering temperature of the powder or the mixture of powders. The layer is brought to the sintering temperature by scanning with a laser beam the layer such that a selected part of the powder, corresponding to one of the digitized sections of the object to be produced, is sintered in solid phase by the additional energy supplied by the laser. Additional layers of the powder or the mixture of powders are spread, heated and scanned with the laser beam until all the digitized superposed sections of the object to be produced are obtained.
