Beschreibung
Zusammenfassung:	The invention relates to a method for manufacturing a compressor impeller or rotor comprising a hub (21) that carries blades (26), involving a step of manufacturing a hub (21) which comprises all or some of the blades (22), and a step of additive manufacture by adding localised material using a method such as the LMD process to form or finish each blade (26). L'invention concerne un procédé de fabrication d'un rouet ou d'une roue de compresseur comprenant un moyeu (21) portant des pales (26), comportant une étape de fabrication d'un moyeu (21) comportant tout ou partie des pales (22), et une étape de fabrication additive par ajout de matière localisée avec un procédé tel que le procédé LMD pour former ou terminer chaque pales (26).
