Zusammenfassung:	The present disclosure is directed to a method for manufacturing a rotor blade component, such as shear web, of a rotor blade of a wind turbine. The method includes forming, via 3-D printing, an intemal lattice structure of the rotor blade component. More specifically, the internal lattice structure includes a plurality of open cells. In addition, the method includes covering at least a portion of the internal lattice structure with an outer skin layer to form the rotor blade component. La présente invention concerne un procédé de fabrication d'un composant de pale de rotor, tel qu'une bande de cisaillement, d'une pale de rotor d'une éolienne. Le procédé comprend la formation, par impression 3D, d'une structure de treillis interne du composant de pale de rotor. Plus spécifiquement, la structure de réseau interne comprend une pluralité de cellules ouvertes. De plus, le procédé consiste à recouvrir au moins une partie de la structure de treillis interne avec une couche de peau externe pour former le composant de pale de rotor.
