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.
Claims10
A process 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 powder material and solidification of the layers at points corresponding to the cross-section of the object, the process comprising fluidizing the powder in a supply container prior to solidification of a layer by supplying a fluid medium to the supply container to effect fluidization, the process further comprising the step of controlling and/or regulating at least one of a variant selected from the group consisting of a temperature, a pressure and a volume flow of the fluid medium.
A process 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 powder material and solidification of the layers at points corresponding to the cross-section of the object, the process comprising fluidizing the powder in a supply container prior to solidification of a layer by supplying a fluid medium to the supply container to effect fluidization and controlling or regulating the temperature of the fluid medium.
A process 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 powder material and solidification of the layers at points corresponding to the cross-section of the object, the process comprising fluidizing the powder in a supply container prior to solidification of a layer by supplying a fluid medium to the supply container to effect fluidization and moistening the powder or chemically treating the powder via the supplying of fluid medium.
