Abstract: A method of removing powder material from a cavity of a part, including supporting the part such than an opening defined in an outer surface of the part and communicating with the cavity is exposed and configured to allow the powder material contained within the cavity to exit therethrough; fluidizing the powder material contained in the cavity; and flowing at least a portion of the fluidized powder material contained in the cavity out of the cavity and out of the part through the opening. The part may be made from additive manufacturing. The powder material may be fluidized through vibration of the part.
