This is an inductive coil that is 3D printed. The first one is ordinary PLA in aqua translucent from Atomic Filament. I have some Functionalize Graphene as well as some Proto-pasta conductive PLA for printing more of them. I did not want to waste the more expensive filaments on a test run for printability and separation potential.
I am happy to report that the coil printed and separated flawlessly. Don't ya just love a quality 3D printer?
Next I will design a core for the magnetic iron hollow cylinder shape. It will have a negative of the coil such that it keeps the turns separate.
