Abstract

The invention relates to a device ( 10 ) for generative production of at least one component area of a component ( 12 ), in particular of a component ( 12 ) of a flow machine. Therein, the device ( 10 ) can include at least one lowerable component platform ( 16 ) with at least one construction and joining zone ( 20 ) for receiving at least one powder layer of a component material, at least one heating device ( 24, 28 ) movable relative to the component platform ( 16 ) and at least one radiation source for generating at least one high-energy beam ( 22 ), by means of which the powder layer can be locally melted and/or sintered to a component layer in the area of the construction and joining zone ( 20 ), as well as at least one suction and/or gas supply device ( 36 ) disposed on the heating device ( 24, 28 ). However, the device ( 10 ) can also include at least one coater ( 14 ).

First claim

The invention claimed is:

1. A device for generative production of at least one component area of a component of a flow machine, comprising:
at least one lowerable component platform with at least one construction and joining zone for receiving at least one powder layer of a component material;
at least one heating device movable relative to the component platform; and
at least one radiation source for generating at least one high-energy beam, by means of which the powder layer can be locally melted and/or sintered to a component layer in the area of the construction and joining zone; and
at least one suction and/or gas supply device which is mechanically connected to, and movable with, the heating device such that a working and operating area of the high-energy beam in the area of the construction and joining zone is in an operating area of the suction and/or gas supply device.

2. The device according to claim 1 , wherein the device has at least one coater for applying the at least one powder layer of the component material to the construction and joining zone of the component platform, wherein the coater is movable relative to the component platform.

3. The device according to claim 2 , wherein the heating device is movably or non-movably mechanically connected to the coater.

4. The device according to claim 1 , wherein the device has at least one coater for applying the at least one powder layer of the component material to the construction and joining zone of the component platform, wherein the coater is movable relative to the component platform and wherein the heating device is movably or non-movably mechanically connected to the coater and wherein the coater includes at least one moving unit on which at least one heating device is disposed.

5. The device according to claim 1 , wherein the heating device includes an induction coil.

6. The device according to claim 1 , wherein the high-energy beam includes a laser or electron beam.

7. A device for generative production of at least one component area of a component of a flow machine, comprising:
at least one coater for applying at least one powder layer of a component material to at least one construction and joining zone of at least one lowerable component platform, wherein the coater is movable relative to the component platform; and
at least one radiation source for generating at least one high-energy beam, whereby the powder layer can be locally melted and/or sintered to a component layer in the area of the construction and joining zone; and
at least one suction and/or gas supply device is mechanically connected to, and movable with, the coater such that a working and operating area of the high-energy beam in the area of the construction and joining zone is in an operating area of the suction and/or gas supply device.

8. The device according to claim 7 , wherein at least one heating device is movably or non-movably mechanically connected to the coater.

9. The device according to claim 7 , wherein the suction and/or gas supply device is disposed on the coater such that a working and operating area of the high-energy beam in the area of the construction and joining zone is in an operating area of the suction and/or gas supply device and wherein at least one heating device is movably or non-movably mechanically connected to the coater.

10. The device according to claim 9 , wherein the coater includes at least one moving unit, on which at least one heating device is mechanically connected.

11. The device according to claim 7 , wherein the heating device includes an induction coil.

12. The device according to claim 7 , wherein the high-energy beam includes a laser or electron beam.

13. A method for generative production of at least one component area of a component of a flow machine, comprising the following steps:
a) applying at least one powder layer of a component material to at least one construction and joining zone of at least one lowerable component platform;
b) locally melting and/or sintering the component material in layers by supplying energy by at least one high-energy beam in the area of the construction and joining zone for forming a component layer;
c) lowering the component platform in layers by a predefined layer thickness; and
d) repeating the steps a) to c) until completion of the component area,
wherein before and/or during and/or after exposure by the high-energy beam, deposits, splashes and/or process exhaust gases of the generative production process are removed from the construction and joining zone by at least one suction and/or gas supply device mechanically connected to, and movable with, a heating device such that a working and operating area of the high-energy beam in the area of the construction and joining zone is in an operating area of the suction and/or gas supply device, the heating device being movable relative to the component platform and/or on at least one coater movable relative to the component platform for applying the component material.
