Abstract
A device for treating powder for a device for producing a three-dimensional object by means of a generative manufacturing process, in particular by means of laser sintering, is provided, having a supply container (1) for the powder with a base (2) and a side wall (3), characterised in that a chamber, which has a wall (4) which is permeable to a fluid medium towards the container interior, is provided in the container (1), and in that a device (9) for supplying a fluid medium into the chamber is provided.

1-20. (canceled)
A device for treating powder for an apparatus for producing a three-dimensional object by means of a generative manufacturing process, in which the object is built up by sequential application of layers of a pulverulent material and solidification of the layers at points corresponding to the cross-section of the object, the device comprising:
- a supply container for the powder comprising an interior, a base, a side wall and a cross-section of the interior parallel to the base;
- a chamber having a boundary with the container which is permeable to a fluid medium in at least one region towards the container interior;
- and a conduit for supplying the fluid medium into the chamber.
An apparatus for producing a three-dimensional object, the apparatus comprising:
- a support on which the object is built up;
- a coater for applying layers of a solidifiable powder material to the support or a previously solidified layer;
- a solidification device for solidifying the powder material at points in a particular layer corresponding to the object;
- and
- a powder treatment device for treating the powder with a fluid prior to solidification, the device comprising:
- a supply container for the powder comprising an interior, a base, a side wall and a cross-section of the interior parallel to the base;
- a chamber having a boundary with the container which is permeable to a fluid medium in at least one region towards the container interior;
- and a conduit for supplying the fluid medium into the chamber.
