Abstract
Official abstract text for this publication.
A method includes placing an additively manufactured article having one or more internal channels in a non-reactive liquid to remove remainder powder from within the one or more internal channels, wherein the non-reactive liquid is a gas at room temperature and/or pressure. Placing the additively manufactured article in the non-reactive liquid includes can include placing the additively manufactured article in liquid nitrogen.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: placing an additively manufactured article having one or more internal channels in a non-reactive liquid to remove remainder powder from within the one or more internal channels, wherein the non-reactive liquid is a gas at room temperature and/or pressure. 2. The method of claim 1 , placing the additively manufactured article in the non-reactive liquid includes placing the additively manufactured article in liquid nitrogen. 3. The method of claim 1 , further comprising additively manufacturing the additively manufactured article. 4. The method of claim 3 , wherein additively manufacturing the additively manufactured article includes powder bed fusion and/or electron beam melting. 5. The method of claim 1 , further comprising thermally contracting a blockage formed by the remainder powder relative to the one or more internal channels of the additively manufactured article to remove the blockage. 6. The method of claim 1 , further comprising allowing bubbles to contact the remainder powder within the one or more internal channels to liberate remainder powder. 7. The method of claim 6 , wherein allowing the bubbles to contact the remainder powder includes allowing the non-reactive liquid to boil to liberate the remainder powder. 8. The method of claim 6 , wherein allowing the bubbles to contact the remainder powder includes agitating the non-reactive liquid to create bubbles. 9. The method of claim 8 , wherein agitating the non-reactive liquid includes using a tuyere to apply vibration to the non-reactive liquid. 10. The method of claim 1 , further comprising applying a vibratory force to the non-reactive liquid while the additively manufactured article is within the non-reactive liquid to vibrate the remainder powder within the one or more internal channels of the additively manufactured article. 11. The method of claim 10 , wherein applying a vibratory force to the non-reactive liquid includes applying a vibratory force to a container holding the non-reactive liquid.
