Device and method for additively producing at least one component region of a component

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.

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.
