Custom FDM nozzle for 3D printing in a magnetic field
Additive manufacturing has shown great promise for enhanced prototyping of magnets. We will use Fused Deposition Modeling (FDM) to print magnets with predefined magnetic orientations, by incorporating an octopol magnet into a custom 3D printer.
Keywords: Additive Manufacturing, 3D Printing, Magnets, Fused Deposition Modeling
Currently all magnets are made by pressing or injection molding which does not only limit the design but is also extremely expensive for a small number of units, such as required for prototyping. As such we will improve additive manufacturing of magnets to include predefined magnetic orientations.

Design a custom FDM nozzle to fit inside the octopol magnet without interfering with the magnetic field. You will need to consider the available space and choose and arrange materials in such a way that they do not interfere
Design a filament feeder and hot bed do complement your design. Finally, we will use a magnetic filament to print.
