Abstract
Disclosed is a system for depowdering a workpiece formed from a reactive powder by an additive manufacturing process. The system includes a powder removal enclosure, an inert gas source, a sealed ultrasonic transducer, an oxygen sensor, and a controller coupled to the sealed ultrasonic transducer and the oxygen sensor. The controller is configured to perform a plurality of operations including monitoring the oxygen sensor to observe an oxygen level within the powder removal enclosure as an inert gas from the inert gas source displaces a gas environment within the powder removal enclosure, and applying electrical power to the sealed ultrasonic transducer within the powder removal enclosure to ultrasonically remove a residual amount of the reactive powder from the workpiece based on determining that the oxygen level within the powder removal enclosure is below a minimum oxygen level threshold.
