Embodiment Construction

[0016] See first illustration 8 of the accompanying drawings.

[0017] exist Figure 8 A device 1 for producing a component 2 by successively solidifying individual layers 3 of a powdery curable construction material 4 is schematically shown in , wherein the construction material 4 is melted or melted by laser radiation 5 and is cooled are then connected into solid components. Such a device 1 comprises a coating device 6 for applying a powder layer 3 onto a preferably height-adjustable carrier 7, a metering device 8 for supplying the coating device with building material 4, a An overflow container 9 for unneeded construction material 4 and a sieve device 10, which is designed according to FIG. feature. In the prior art, the sieving device 10 comprises a powder inlet 11, whereby excess building material 4 from the overflow container 9 is fed into the sieving process. The sieving material consisting of particles of different sizes falls onto the sieve 12 of the sifting devic...

Abstract

The invention relates to a device (1) for the generative production of components (2) by successively curing individual layers (3) of a powdery construction material (4) curable by the action of radiation A screening device (10) for use in , comprising a coating device (6) for applying a layer (3) to a carrier (7), a metering device for supplying powdered building material (4) (8) An overflow container (9) for containing building material (4) not needed during the cladding process, which can be fed to the overflow container for sifting during the building process ( 9) A screening device (10) for powdered materials, wherein the sieve (12) of the screening device (10) is designed obliquely at least in sections such that the construction material (4) to be screened is impacted After onto the sieve ( 12 ), it is first guided at an initial speed over the surface of the sieve ( 12 ) and then the conveying speed of the building material ( 4 ) over the sieve surface is reduced or reduced to a lower speed value.

Description

technical field [0001] The invention relates to a sieve device for use in a device for the generative production of components by successively solidifying layers of powdery construction material. In such generative construction devices, a powdery construction material is applied layer by layer to the base, the layers are melted or fused in partial regions by means of radiation—in particular laser radiation—and thus joined to form a solid body . A known generative construction device comprises a cladding device for applying a powder layer onto a carrier body, a metering device for supplying the cladding device with construction material, an overflow container for containing the construction material, which is It is not required during the cladding process and can be fed to a screening device for screening construction material that is discharged into an overflow container during the construction process. Background technique [0002] Known sieve devices used in generative c...
