POWDER MONITORING

A method including filling an internal passage (201) of an additively manufactured (AM) article (200) with a state change fluid (205), causing the state change fluid to change from a first state having a first viscosity to a second state that is either solid or has a second viscosity that is higher...

Beschreibung
Zusammenfassung:	A method including filling an internal passage (201) of an additively manufactured (AM) article (200) with a state change fluid (205), causing the state change fluid to change from a first state having a first viscosity to a second state that is either solid or has a second viscosity that is higher than the first viscosity within the internal passage, causing the state change fluid to change back from the second state to the first state, removing residual powder from the additively manufactured article by flushing the state change fluid from the internal passage, measuring electrical impedance of a piezoelectric wafer connected to the additively manufactured article, and determining that more than a threshold amount of residual powder remains within the AM article based on the measured electrical impendence of the additively manufactured article being outside of a selected range from an expected impendence value.
