    摘要: A surface equalization apparatus designed to be compatible with a wide variety of part technologies, composite materials and part geometries. The apparatus works with software, chemistry, abrasives and media and includes an oblong, elongated input tank for holding media and a part. The input tank is connected to a motor mount, which is connected to an eccentric motor. When the motor is activated, the input tank begins to move in a vibrational, sinusoidal manner. The motion of the tank on attached springs generates a rotational flow of media in the tank. This creates a low amplitude/high frequency movement of the part through the tank. Surface structures divert media to prevent the part from contacting the side of the tank. Spray nozzles are positioned above the input tank. Acoustic damping foam is positioned around the central components. A cooling fan allows airflow through the apparatus.

    摘要: A process for removing support material from a part made by an additive manufacturing process is disclosed. The part may be arranged in a media filled tank. Ultrasonic waves are directed for the part and/or support material. Ultrasonic waves from an ultrasonic transducer are applied to a part or support material and cause the part to vibrate. The frequency of the ultrasonic energy may be tuned to cause the part and/or the support material to vibrate at its resonant frequency. The support material may have different properties, such as density, geometry, material, or porosity. Such differences may allow the support material to resonate in response to the applied ultrasonic energy waves at a different ultrasonic frequency than, the part itself.
