A method of depowdering objects (e.g., heat exchangers) having small and/or complex internal geometries and manufactured using an additive manufacturing technique performed with a powder material. The method includes applying a pressurized fluid to the objects via a pressurized fluid applicator operatively coupled to the object, thereby removing a portion of unbound powder material on or in the object. The method further includes applying vortex vibration to the object via a vortex vibration source operatively coupled to the object, thereby loosening a portion of the unbound powder material remaining on or in the object, and applying the pressurized fluid to the object via the pressurized fluid application, thereby removing a portion of the loosened, unbound powder material from the object. The latter two applying steps are repeated until a specified amount of the unbound powder material has been removed from the object.
