Abstract
A method for creating a blade () for a turbo-engine and such a blade are disclosed. Components () of the blade are produced by an additive production method such as selective laser melting or fusion, while a main body () is produced by casting, for example. The blade components () may consist of a different material than the basic body (). The components or body may carry functions such as serving as drainage slots (). Expense related to the use of additive production methods occurs only for the components () in which a complicated geometry, for example, must be implemented. The remaining components in the form of the main body (), comprising the blade (), the blade foot () and the blade head (), can be cost-effectively implemented as a cast part or a sheet metal part.
