Claim 19:
20. A method, comprising:
printing a three-dimensional (3D) object with a print material comprising a polymer and magnetic particles, wherein the magnetic particles have an average particle diameter of 50 nanometers to 3 microns and comprise 3 to 10 weight percent of the print material;
heating the 3D object to a temperature at approximately a melting temperature of the polymer; and
applying an oscillating magnetic field to the 3D object to align the magnetic particles in the polymer and to rotate the magnetic particles back and forth in accordance with a pattern of oscillation to generate heat that melts regions between layers of the 3D object to fuse the polymer around the magnetic particles and to promote entanglement of polymer chains between the layers.
