Additive manufactured conglomerated powder removal from internal passages

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.

What is claimed is: 
     
         1 . A component, comprising:
 an additively manufactured component with an internal passage; and   an additively manufactured an elongated member within the internal passage.   
     
     
         2 . The component as recited in  claim 1 , wherein the additively manufactured component include a first flange, a second flange, and a conduit with the internal passage therebetween. 
     
     
         3 . The component as recited in  claim 2 , wherein the conduit includes multiple bends. 
     
     
         4 . The component as recited in  claim 2 , wherein the internal passage is non line of sight. 
     
     
         5 . The component as recited in  claim 1 , wherein the additively manufactured elongated member extends along a centerline of the internal passage. 
     
     
         6 . The component as recited in  claim 1 , wherein the additively manufactured elongated member extends along a centerline of the internal passage. 
     
     
         7 . The component as recited in  claim 1 , wherein the internal passage defines an aspect ratio with a diameter to length of less that  1 : 4 . 
     
     
         8 . The component as recited in  claim 1 , wherein a ratio between the internal passage internal diameter and the elongated member outer diameter is between 4.3:1 to 12.5:1. 
     
     
         9 . The component as recited in  claim 1 , wherein the elongated member is between about 0.08 and 0.12 inches (˜2-3 mm) in diameter. 
     
     
         10 . The component as recited in  claim 9 , wherein the internal passage is between about 0.5 and 1.0 inches (˜13-25 mm) in diameter. 
     
     
         11 . A method of additively manufacturing a component, comprising:
 additively manufacturing a component with an internal passage; and   additively manufacturing an elongated member within the internal passage concurrent with additively manufacturing the component.   
     
     
         12 . The method as recited in  claim 11 , further comprising cleaning the internal passage of conglomerated powder with the elongated member subsequent to completion of the additively manufacturing. 
     
     
         13 . The method as recited in  claim 12 , further comprising removing the elongated member from within the internal passage subsequent to cleaning the internal passage. 
     
     
         14 . The method as recited in  claim 13 , further comprising destructively removing the elongated member from within the internal passage subsequent to cleaning the internal passage. 
     
     
         15 . The method as recited in  claim 13 , further comprising pulling the elongated member out of the internal passage subsequent to cleaning the internal passage. 
     
     
         16 . The method as recited in  claim 11 , further comprising removing conglomerated powder from the external surfaces of the completed additively manufactured component. 
     
     
         17 . The method as recited in  claim 16 , further comprising agitating the elongated member within the internal passage to remove clean the internal passage of conglomerated powder of the completed additively manufactured component.
