Additive manufacturing methods are cost and time efficient methods, in particular, for the fabrication of subject-specific MRI hardware components. A novel powder-binder jetting method was developed to deposit variable concentrations of magnetic ink at precise pre-calculated positions to sculpt B0 towards a target distribution via the passive response of the 3D printed shims. Discrete spherical harmonic terms were printed as a proof-of-concept towards the manufacturing of subject-specific passive shims. Stereolithography (SLA) and Laser Powder Bed Fusion (L-PBF) manufacturing methods were developed for the fabrication of subject-specific RF coils. Significant gains in image quality, scan time and subject comfort were observed.
