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.

Claims (10)

1. 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.

2. The method as recited in claim 1 , wherein the vibrating step causes the multiple of agitators to mechanically break semi-sintered conglomerated powder bonds in conglomerated powder surrounding each of the multiple of agitators, thereby working the conglomerated powder out of the internal passage with the multiple of agitators.

3. The method as recited in claim 1 , further comprising additively manufacturing the component with the internal passage and the multiple of agitators in the internal passage.

4. The method as recited in claim 1 , further comprising fixing the component, and then vibrating the component at a natural frequency which excites the agitators such that the agitators vibrate with a force that breaks conglomerated powder bonds surrounding each of the multiple of agitators.

5. 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.

6. The method as recited in claim 5 , wherein each of the multiple of agitators clean the internal passage of conglomerated powder subsequent to completion of the additively manufacturing of the additively manufactured component.
