  • Patent number: 10906249
    Abstract: An additive manufacturing system, and corresponding method, prints a sacrificial component using a 3D printing system that includes a spreading mechanism for spreading unbound powder to form layers of a powder bed and a printing mechanism for jetting binder fluid into the unbound powder to form the sacrificial component. The system forms the sacrificial component with a feature that provides a resistive force to a shear force imposed by the spreading mechanism during the spreading. The system prints a part with the 3D printing system in a coupled arrangement with the sacrificial component. The coupled arrangement in combination with the resistive force is sufficient to immobilize each printed layer of the part to resist the shear force imposed by the spreading mechanism during spreading of the unbound powder above each printed layer of the part. After printing, and before or after post-processing, the part and sacrificial component are separated.

  • Patent number: 10800079
    Abstract: A process for producing a sensor for a biomedical electrode (e.g. an ECG electrode) involves injection molding an electrically conductive resin through a film of a backing material to form the sensor directly in the backing material and coating the contact face of the sensor with a non-polarizable conductive material (e.g. silver-containing material). Additional steps of applying an electrolyte over the non-polarizable conductive material coated on the contact face and applying a liner over the electrolyte results in the biomedical electrode. Biomedical electrode produced thereby have the sensor secured in a film of the backing material with a contact face of the sensor disposed on a first side of the film and a post of the sensor protruding from a second side of the film opposite the first side. The process permits production of one-piece sensors for bioelectrodes in a continuous fashion without the need for studs to retain sensors in a film of the backing material.
