Abstract: Discloses are a method and apparatus for the additive manufacture of components by applying layers of powder material on a substrate or a previously produced part of a component and at least partial fusing of the powder material in the powder layer in line with the component cross-section contour along the powder layer and to an underlying solid material of the component or substrate for the purpose of building up several solid layers one on top of the other. Following fusion of the powder material the solid layer just generated is cleaned of powder material and, prior to deposition of the next solid layer, the edge of the solid layer is post-processed by softening the fusion-bonded material.

Abstract: The invention relates to a method for the additive manufacture of at least one region of a component. Here, at least the following steps are carried out: a) layer-wise application of at least one powder-form component material onto a component platform in the region of a build-up and joining zone; b) layer-wise and local solidifying of the component material by selective exposure of the component material by at least one high-energy beam in the region of the build-up and joining zone, with the formation of a component layer; c) layer- wise lowering of the component platform by a pre-defined layer thickness; and d) repeating steps a) to c) until the component region or the component has been completely fabricated.

Abstract: A method for additively manufacturing at least a portion of a component, in particular a component of a turbomachine. The method includes the following steps: a) depositing at least one powder layer of a component material in powder form layer by layer onto a component platform in the region of a buildup and joining zone; b) locally solidifying the powder layer by selectively irradiating the same using at least one high-energy beam in the region of the buildup and joining zone, forming a component layer; c) lowering the component platform by a predefined layer thickness; and d) repeating steps a) through c) until completion of the component portion or of the component.

Abstract: The invention relates to a method for the additive manufacture of at least one region (16) of a component. Here, at least the following steps are carried out: a) layer-wise application of at least one powder-form component material onto a component platform in the region of a build-up and joining zone (14); b) layer-wise and local solidifying of the component material by selective exposure of the component material by at least one high-energy beam (12) in the region of the build-up and joining zone (14), with the formation of a component layer (15); c) layer-wise lowering of the component platform by a pre-defined layer thickness; and d) repeating steps a) to c) until the component region (16) or the component has been completely fabricated.

Abstract: The invention provides a method for determining a scanning speed of a high-energy beam of a manufacturing device for the additive production of a component, in particular a component of a turbomachine, comprising the steps of guiding of the high-energy beam, which is generated by a radiation source of the manufacturing device, over a surface; detection of the path, irradiated during a predetermined period of time with the high-energy beam, on the surface, by recording respective brightness values on the surface by a detection device during the predetermined period of time; calculation of the scanning speed as a function of the predetermined period of time and of the detected irradiated path by an analysis device. The invention further relates to a method for operating a manufacturing device and to a manufacturing device for the additive production of a component of a turbomachine.
