  • Utilization of magnetic particles to improve z-axis strength of 3D printed objects
    Patent number: 11951683
    Abstract: A method for improving z-axis strength of a 3D printed object is disclosed. For example, the method includes printing a three-dimensional (3D) object with a polymer and magnetic particles, heating the 3D object to a temperature at approximately a melting temperature of the polymer, and applying a magnetic field to the 3D object to locally move the magnetic particles in the polymer to generate heat and fuse the polymer around the magnetic particles to improve a z-axis strength of the 3D object.
    Type: Grant
    Filed: July 11, 2022
    Date of Patent: April 9, 2024
    Assignee: Xerox Corporation
    Inventors: Chunliang Lu, Christopher Wolfe, John Ianni, Mark Mercandetti, John Pawlak, Chieh-Min Cheng
