1. A system comprising a mold for a centrifugal impeller for a turbomachine, the system comprising:
at least one annular insert, wherein the at least one annular insert comprises a plurality of aerodynamic vane inserts configured to reproduce a plurality of aerodynamic vanes of a finished centrifugal impeller, wherein each of the plurality of aerodynamic vanes comprises lateral faces and at least one of an inferior face and a superior face; and
wherein a shaped component encloses external surfaces of each of the aerodynamic vane inserts,
wherein at least one of the plurality of shaped components become integral with at least three faces of each of the plurality of aerodynamic vanes.
