In this study, anisotropic magneto-responsive 3D printer inks have been developed by mixing UV-sensitive photoresist SU8 and Fe Flakes (∼10 um lateral size and ∼ 100 nm thickness). Fe flakes have been synthesized via surfactant-assisted ball milling of Fe powders. Structures with solid loadings up to 70% have been successfully 3D printed. Magnetic cores for toroidal inductors were developed by using the synthesized magneto responsive ink. The magnetic, mechanic, and electrical properties of the printed structures have been evaluated. Toroidal inductors with a quality factor up to 70 at 1 MHz were successfully developed using the 3D printed magnetic cores with 70% solid content.
