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.

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.

SELF-MODIFYING AGITATION PROCESS AND APPARATUS FOR SUPPORT REMOVAL IN ADDITIVE MANUFACTURING AND 3D PRINTED MATERIAL
A process for support material removal for 3D printed parts wherein the part is placed in a media filled tank and support removal is optimized in a multi-parameter system through an artificial intelligence process which may include, but is not limited to, the use of historical data, parametric testing data, normal support removal data, and outputs from other support removal AI models to generate optimally efficient use of each parameter in terms of pulse repetition interval (PRI) and cycle time as defined by pulse width (PW). The input parameters may include heat, circulation, ultrasound and chemical reaction, which are used in sequence and/or in parallel, to optimize efficiency of support removal. Sequentially and/or in parallel, heat, pump circulation and ultrasound may vary in application or intensity. Selection of means of agitation depends on monitored feedback from the support removal tank and application of a statistically dynamic rule based system (SDRBS).
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.
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.
