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.

A mould-forming and sacrificial materials are printed into a plurality of layers. The sacrificial material is removed to leave a void defined by a mould structure formed by the mould-forming material. The void is filled with a part-forming material to form the part defined by the shape of the mould structure. The mould structure is removed from the part to free the part from the mould structure. According to a further method, the part-forming material serves the purpose of supporting the mould-forming material and then forming the part. In this case, the part-forming material can be printed together with a mould-forming material as described above and are then heated to a temperature of approximately 700° C. to activate a binder and then heated to a temperature that melts the part-forming material.
