Abstract

A method for manufacturing a turbomachine component is disclosed, including the steps of producing, by additive manufacturing, a plurality of separate segments of the turbomachine component, having a skin surrounding an empty volume corresponding to a massive part of the turbomachine component; assembling the separate segments of the turbomachine component together forming a semi-finished component, with an empty cavity therein; filling cavity of the semi-finished component with a bulk flowable material; and densifying and solidifying the bulk flowable material in the cavity.
