The invention concerns a sieve device 10 for use in a device 1 for generative manufacture of components 2 by means of successive solidification of individual layers 3 of powdered solidifiable construction material 4 by exposure to radiation, in particular laser radiation 5, through sector by sector melting or fusing and binding of the construction material 4, comprising a coating device 6 for application of the layers 3 on a carrier 7, a dosing device 8 for preparing the powdered construction material 4 for the coating device 6, an overflow container 9 for receipt of construction material 4 not needed in the coating process that can be fed to the sieve device 10 for sieving the powder material into the overflow container 9 during the construction process, wherein a sieve 12 of the sieve device 10 is configured at least in sections to be inclined in a way that the construction material 4 after appearance on the sieve to be sieved is first brought across the surface of the sieve with an initial velocity and then the transport velocity of the construction material 4 slows or is reduced to a lower velocity over the surface of the sieve.
A sieve device (10) for application in a device (1) for generative manufacture of components (2) by sequential solidification of individual layers (3) from powdered solidifiable construction material (4) by exposure to radiation, in particular laser radiation (5) by means of sector by sector melting or fusing and binding the construction material (4) comprising a coating device (6) for application of the layers (3) on a carrier (7), a dosing device (8) for preparation of the powdered construction material (4) for the coating device (6), an overflow container (9) for intake of construction material (4) not needed for the coating process that can be fed to the sieve device (10) for sieving the powder material diverted into the overflow container (9) during the construction process, characterized in that a sieve (12) of the sieve device (10) is at least in sections configured to be inclined so that the construction material (4) to be sieved after impinging on the sieve (12) is at first brought with an initial velocity over the surface of the sieve (12) and then the transport velocity of the construction material (4) is reduced or brought to a lower speed across the surface of the sieve.
