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： Systems and methods according to the invention are used for removal of unwanted material from an additively manufactured object by application of sonic energy are disclosed. Application of sound at specific frequencies, specific amplitudes and specific waveforms to specific materials causes physical displacement of such materials. When applied to objects formed by additive manufacturing and unwanted material formed with such objects, the displacement causes the unwanted material to break away from the object. Advantageously, the unwanted material removed from the additively manufactured object can be recycled.

摘要： An apparatus and method for removing support material from a part formed by three-dimensional (3D) printing. The support removal machine contains a tank for submersion of a 3D printed part into a liquid mass. The liquid mass circulates in the tank in a controlled manner such that submerged parts remain centrally suspended in the tank, regardless of the material, density and geometry comprising the part. The part circulates and rotates in conjunction with the rotational flow of the liquid mass for uniform exposure to means of support removal. During rotation, the part may be subjected to multiple means of agitation that include heat, chemical and ultrasonic, in order to optimize energy use and maximize efficiency of the removal of support material.

摘要： An apparatus and method are disclosed for removing support material or resin from additively manufactured parts. The apparatus includes a processing pump at least a portion of which is located in or adjacent to a processing tank filled with a liquid formulation suitable for removal of support material or resin from additively manufactured parts. The processing pump is adapted to create a vortex within the liquid formulation in the processing tank.

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： 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.
