Abstract

An electromagnet alignment system for in-situ alignment of a magnetic particulate material is provided. The magnetic particulate material is dispensed through an orifice of a dispensing nozzle used for 3D printing. The system has an electromagnet assembly having a coil. The coil is configured to generate a pulsed magnetic field having a target magnetic flux intensity upon energization of the coil when the magnetic particulate material is being heated and moved through the dispensing nozzle. As a result, the magnetic particulate material is at least partially aligned with respect to a direction by the pulsed magnetic field. The system further includes a power source for implementing the energization of the coil.
