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.

Abstract: A method of preparing a distal femur for implantation of a femoral implant is described. The distal femur is resected to accommodate placement of a trial implant thereon. The trial implant is then placed against the resected distal femur to locate an optimal position for the femoral implant. The trial implant comprises one or more apertures through which holes are drilled in the distal femur and into which trial pegs are inserted into the distal femur to secure the trial implant to the distal femur. The surgeon then evaluates whether the holes in the femur are located appropriately to securely implant the femoral implant onto the femur. The trial implant is ultimately removed in favor of a final implant.
