Abstract
A component includes an additively manufactured component with an internal passage; and an additively manufactured elongated member within the internal passage. A method of additively manufacturing a component including additively manufacturing a component with an internal passage; and additively manufacturing an elongated member within the internal passage concurrent with additively manufacturing the component.
Claims6
A method of additively manufacturing a component, comprising:
- vibrating a component at a particular known natural frequency of a multiple of agitators within a non-line of sight internal passage of an additively manufactured component to clean the internal passage of conglomerated powder with the multiple of agitators subsequent to completion of the additively manufacturing of the additively manufactured component, wherein the multiple of agitators comprise additively consolidated powder.
A method of additively manufacturing a component, comprising:
- additively manufacturing a component with a non-line of sight internal passage;
- additively manufacturing a multiple of agitators within the internal passage concurrent with additively manufacturing the component, wherein the agitators comprise additively consolidated powder;
- and
- fixing the component, and then vibrating the component at a natural frequency to excite the agitators such that the agitators vibrate with a force that breaks semi-sintered conglomerated powder bonds in conglomerated powder surrounding each of the multiple of agitators.
