Turbine blade generative prepared and apparatus and process for their preparation

The present invention relates to a process for the production of gas turbine components, particularly air turbine components, preferably low-pressure turbine blades of a powder which is capable, selectively sintered by localized introduction of radiation energy, wherein the sintering in a closed, the first housing (2) is carried out so that a is defined atmosphere adjustable, wherein in the same first housing (2) or a second gas-tight housing connected to the first housing is produced, the powder or at least a portion of the powder. The invention further relates to a corresponding apparatus and a gas turbine blade made therewith.
