Abstract

The invention relates to a method for additively manufacturing at least one component region of a component, in particular of a turbine or compressor component, said method comprising at least the following steps: applying a layer of powder ( 10 a - c ) to a component platform in the region of a building and joining area; locally melting and/or sintering the powder layer ( 10 a - c ), wherein, in the region of the building and joining area, at least one high-energy beam is moved in relation to the component platform, selectively impinging the powder layer ( 10 a - c ), at least part of which at least one high-energy beam and the component platform are moved in relation to one another, in the form of a parallel arrangement ( 16 ) arranged along a linear feed direction ( 12 ); lowering the component platform by a predetermined layer thickness in a lowering direction; and repeating the above-mentioned steps unfil the component region is completed.

First claim

1 - 13 . (canceled)

14 . A method for additively manufacturing at least one component region of a component of a turbine or a compressor, comprising the steps of:
a) applying a powder layer ( 10 a - c ) to a component platform in the region of a building and joining area; b) locally melting and/or sintering the powder layer ( 10 a - c ) in that at least one high-energy beam is moved in relation to the component platform in the region of the building and joining area and selectively impinges the powder layer ( 10 a - c ), wherein the at least one high-energy beam and the component platform are moved in relation to each other at least in certain areas in the form of a parallel arrangement ( 16 ) disposed along a linear feed direction ( 12 ); c) lowering the component platform by a predetermined layer thickness in a lowering direction; and d) repeating the steps a) to c) until completion of the component region, wherein the at least one high-energy beam and the component platform are moved in relation to each other in at least two different powder layers ( 10 a - c ) such that the respective parallel arrangements ( 16 ) of the respective powder layers ( 10 a - c ) are arranged at different angles to the respective feed direction ( 12 ) in powder layer regions located above each other in lowering direction.

15 . The method according to claim 14 , wherein the at least one high-energy beam and the component platform are moved in relation to each other in at least two consecutive powder layers ( 10 a - c ) and/or in all of the powder layers ( 10 a - c ) such that the respective parallel arrangements ( 16 ) of the respective powder layers are arranged at different angles to the respective linear feed direction ( 12 ) in powder layer regions located above each other in lowering direction and adjoining to each other.

16 . The method according to claim 14 , wherein the at least one high-energy beam and the component platform are moved in relation to each other at least in certain areas in strictly alternating linear movements along at least one linear feed direction ( 12 ) to form a parallel arrangement ( 16 ).

17 . The method according to claim 14 , wherein the at least one high-energy beam and the component platform are moved in relation to each other in at least two different powder layers ( 10 a - c ) such that the respective linear feed directions ( 12 ) are identically oriented in powder layer regions located above each other in lowering direction.

18 . The method according to claim 14 , wherein the component is inductively heated by at least one induction coil at least in certain areas and/or at least in times.

19 . The method according to claim 18 , wherein the angle of at least one parallel arrangement ( 16 ) to the associated linear feed direction ( 12 ) is selected depending on a heating characteristic of the at least one induction coil.

20 . The method according to claim 14 , wherein the at least one high-energy beam and the component platform are moved in relation to each other in at least one powder layer ( 10 a - c ) such that at least two straight lines ( 14 ) of the concerned parallel arrangement ( 10 a - c ) have identical and/or different lengths.

21 . A device for additively manufacturing at least one component region of a component of a turbine or a compressor, comprising:
at least one powder supply for applying at least one powder layer ( 10 a - c ) to a building and joining area of a component platform capable of being lowered; at least one radiation source for generating at least one high-energy beam, by which the powder layer ( 10 a - c ) can be locally melted and/or sintered in the region of the building and joining area; and a movement device, by which the at least one high-energy beam and the component platform can be moved in relation to each other at least in certain areas in the form of a parallel arrangement ( 16 ) disposed along a linear feed direction ( 12 ); wherein the movement device is formed to move the at least one high-energy beam and the component platform in relation to each other in at least two different powder layers ( 10 a - c ) such that the respective parallel arrangements ( 16 ) of the concerned powder layers ( 10 a - c ) are arranged at different angles to the respective linear feed direction ( 12 ) in powder layer regions, which are located above each other in lowering direction of the component platform.

22 . The device according to claim 21 , wherein at least one induction coil is provided, by which the component can be inductively heated at least in certain areas and/or at least in times.

23 . The device according to claim 22 , wherein the at least one induction coil is disposed rotation-proof with respect to the component platform.

24 . The device according to claim 22 , wherein the movement device is formed to adjust the angle of at least one parallel arrangement ( 16 ) to the associated linear feed direction ( 12 ) depending on a heating characteristic of the at least one induction coil.

25 . The device according to claim 23 , wherein the movement device is formed to adjust the angle of at least one parallel arrangement ( 16 ) to the associated linear feed direction ( 12 ) depending on a heating characteristic of the at least one induction coil.

26 . The device according to claim 21 , wherein a control and/or regulating device is provided, which is formed to operate the movement device and/or the radiation source depending on layer information of the component region to be manufactured and/or depending on material information of the powder layer.

27 . The method according to claim 14 , wherein the component is configured and arranged for use in a turbine or compressor.

28 . The device according to claim 21 , wherein the component is configured and arranged for use in a turbine or compressor.
