Zusammenfassung:	A method for manufacturing a blade in composite material with added metal leading edge for gas turbine aeroengine, the method including producing a batch of plurality of blade bodies in composite material; creating a digital model of a blade body from a blade in the batch of plurality of blade bodies; creating a digital model of a theoretical final blade including a leading edge; generating a digital model of a leading edge from the digital model of a blade body and final blade model; manufacturing at least one leading edge via additive manufacturing from the generated leading edge digital model; bonding each manufactured leading edge onto a blade body from the batch of plurality of blade bodies.
