  • Patent number: 10582619
    Abstract: An apparatus, system, and method for automatically dispensing and embedding components into three-dimensional parts. In an example embodiment, a direct wire embedding head can be fixed on an automation motion system. The direct wire embedding head begins and terminates an embedded wire pattern on a layer or on a surface of a three-dimensional part in order to automatically create the embedded wire pattern. A sensor is located on an embedding surface wherein the embedded wire pattern is embedded. The sensor can measure the distance between the direct wire embedding head and the embedding surface. A predefined distance can be maintained to ensure successful embedding results for the embedded wire pattern by automatically adjusting a position of the direct wire embedding head in response to feedback from the sensor.

    Abstract: An embedded material and an embedding apparatus and method. A compatible solute can be dissolved in a solvent. The object to be embedded can be coated with the solvent/plastic solution using, for example, addition and/or condensation polymerization. The solvent can be removed. The coated object can be inserted, snap fit, or submerged into a partially 3D printed substrate with or without the aid of ultrasonic embedding, thermal energy, joule heating, and/or the use of adhesives, and the 3D printing process resumes in order to fully embed the coated object within the 3D printed substrate. The coated object can be inserted, snap fit, or submerged into a partially 3D printed substrate with or without the addition of ultrasonic embedding, thermal energy, joule heating, and/or adhesives, and the 3D printing process resumes in order to fully embed the coated object within the 3D printed substrate.
