As the popularity of 3D printing to create objects for practical use increases, it is becoming increasingly important that the printed objects are made stronger. Currently, filament-based 3D printed objects have weakness in the Z/vertical direction due to minimal adhesion between subsequent layers of deposited material. Printed composites have improved strength in the X-Y plane due to the alignment of fibers. In this presentation, the impacts of nanowire fiber alignment in the Z direction during extrusion printing is investigated. Magnetic nanowires of different lengths are compared to obtain optimal fiber length for interlocking strong bonds between printed layers. An experimental test-bed is implemented to visualize particle orientation and agglomeration as the particles pass through a magnetic field. Particle Image Velocimetry also shows the behavior of the particles in resins of different viscosities.
