Abstract
Removing unfused powder from internal passages of an additive-manufacture part includes attaching piezoelectric transducers to a plurality of locations on an exterior of the part. The part is vibrated by driving the piezoelectric transducers at varying amplitudes and frequencies. An amount of the unfused powder that exits the part is monitored.
