Impeller for a flow machine and method for producing an impeller

A method for producing an impeller of a flow machine, comprising a base body and at least one impeller blade, wherein the base body and the impeller blade are connected in a material-locking manner, the method comprising:

• a) processing a blank formed from solid material to generate a first partial section of the base body,
• b) applying at least one material layer to the first partial section of the base body for generating a second partial section of the base body, at least in sections, by using an additive manufacture method, and
• c) applying at least one material layer to at least the first partial section or the second partial section for generating at least one impeller blade on the base body, at least in sections, by using an additive manufacture method.
