A method for manufacturing a component of a rotary machine is proposed, the component extending in an axial direction (A) as well as in a radial direction per pendicular thereto, and having at least one inner channel (7), which extends from a first end (72) in a center (6) of the component to a second end (71) at a radial limiting surface (42) of the component and which is at least partially closed, where in a blank (10) is provided, comprising the center (6) of the component and which 10 is limited by an outer surface (11) in the radial direction (R), wherein the maximum dimension (Dl) of theouter surface (11) in the radial direction (R) is smaller than the dimension (D2) of the limiting surface (42) in the radial direction, wherein fur ther a first subtractive process step is performedwherein a part of the channel (7) is manufactured by a machining process, with said part extending from the first 15 end (72) of the channel to the outer surface (11) of the blank (10) and wherein afterwards the channel (7) is finished by means of a build-up process on the blank (10). Furthermore, a corresponding method for repairing is proposed as well as a component manufactured or repaired to such a method.
