摘要： Described are finishing mediums for removing support material and/or for surface finishing of objects made via additive manufacturing techniques. The finishing medium is an aqueous solution containing 1-20% by weight a polyol, 1-20% by weight an anti-corrosion agent, 0.001-10% by weight a hydrotrope. The finishing medium may optionally suspend media particles, thereby forming a finishing suspension. Also described are methods of using the finishing media and finishing suspensions described herein.

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： An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part is disclosed. The apparatus may include a chamber, a support surface within the chamber, one or more nozzles within the chamber, a tank positioned below the nozzles, and a vision system. The vision system includes one or more cameras and other imagery obtaining sensors located in the chamber. The cameras and sensors obtain imagery of the additively manufactured part as it is being sprayed to finish the part. The imagery is displayed on a display panel located outside the apparatus or stored for later playback.

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.

摘要： Methods and systems according to the invention may be used to modify a manufacturing plan for an object manufactured by an additive manufacturing process. A digital representation of a desired object and a manufacturing plan may be compared to manufacturing information generated via an evaluation of such an object. Based on that comparison, the manufacturing plan may be modified so that that object or a subsequent object is highly similar to the desired object.

摘要： An improved exhaust system and method for an apparatus that removes support material from additively manufactured parts is disclosed. The apparatus includes an enclosed chamber in which the additively manufactured parts are placed. A heated detergent fluid is sprayed at the additively manufactured parts. The improved exhaust system exhausts heated air from the chamber. The improved exhaust system includes an exhaust channel having an inlet end open to the chamber through which heated air from the chamber is caused to flow. Relatively cooler air is caused to flow across the outside of the exhaust channel. When the heated air from the chamber encounters the exhaust channel across which the relatively cooler air is caused to flow, evaporated fluids in the heated air condense and fall back into the chamber. The improved exhaust system can be retrofitted onto older models of the support removal apparatus that do not have the improved exhaust system.

摘要： An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part (the “AM part”) is disclosed. The apparatus may include a chamber, a support surface within the chamber, and one or more nozzles within the chamber. The nozzles may be the same size or different sizes. The support surface may be configured to support the AM part. The support surface may have one or more openings sized and configured to allow the fluid to pass through the opening(s). The nozzles may be configured to spray a fluid at the AM part, and the spray may be an atomized or semi-atomized spray of the fluid. For removing support material from parts with internal spaces, such as cavities or passages, the apparatus can include a nozzle at the end of an adjustable flexible hose member that can be adjusted to spray into an internal space of the part. Alternatively, for removing unwanted support material from multiple parts with internal spaces, the apparatus may include a submersion tank.
