Problems solved by technology

[0012] However, if it is desired to rebuild the part using additive and / or selective powder bed-based methods (such as selective laser melting), the above fluctuations will produce unacceptable results, or make multiple parallel repairs by powder bed-based methods. Parts become very complex

Embodiment Construction

[0047] In the exemplary embodiments and drawings, elements that are the same or function in the same manner may be provided with the same names, respectively. The depicted elements and their mutual dimensions are in principle not drawn to scale, but rather individual elements may be drawn with exaggerated thickness or size for improved clarity and / or for ease of understanding.

[0048] figure 1 A perspective view of device 100 is shown. Preferably, the apparatus 100 is used in a facility for additive manufacturing based on a powder bed, preferably by selective laser melting (SLM). The device 100 has a base plate 1 . Accordingly, the base plate is a base plate for the additive manufacturing of metal components, in particular turbine elements.

[0049] The base plate 1 may be a build platform similar to that of a conventional additive manufacturing facility, eg a steel based and / or low deformation base plate.

[0050] The main surface of the bottom plate 1 is square or rectang...

Abstract

The invention relates to a method and to device for the powder bed-based additive building up of a plurality of identical components (10), comprising the fixing of each of the components (10) on a base plate (1) by means of a retaining apparatus (2), the adjusting of a vertical position of at least some of the fixed components (10) relative to the base plate (1), such that a structural peak (11) of each component (10) is spaced apart from the base plate (1) within a predetermined tolerance range (TB), providing a powder bed (3) of a building material on the base plate (1) up to a height of thetolerance range (TB) and the layered, additive building up of material on each of the structural peaks (11) of the components (10).

Description

technical field [0001] The invention relates to a method for the additive manufacturing of a plurality of identical parts, in particular for repairing parts, based on a powder bed, and a corresponding device. Background technique [0002] These components (preferably identical components) are particularly suitable for use in a turbine, preferably in the hot gas path of a gas turbine. Preferably, these components are turbine rotor blades or airfoils. Accordingly, the component preferably comprises or consists of a nickel-based or cobalt-based superalloy, respectively. The alloy may be precipitation hardenable or precipitation hardenable. Alternatively or additionally, the components may be worn components and / or partially manufactured or partially constructed components. [0003] As powder bed methods, generative or additive manufacturing methods include, for example, selective laser melting (SLM) or laser sintering (SLS) or electron beam melting (EBM). Likewise, additive...
