Stable and well characterized anthropomorphic MR-phantoms for quantitative MRI of T1 and T2 measurements are still lacking. We investigate the potential application of additive manufacturing of silicone to produce multi-compartment MR-phantoms with well characterized relaxation properties. Various two-component silicone types with different mixture ratios were investigated. Additionally, the influence of admixing colors to modulate relaxation times was studied. First bi-phasic test samples were designed, produced by different commercial 3D printing sources, and characterized.
