The 3D organ phantom is used in the medical industry as a medical simulator that replaces cadavers or animal organs. To produce a realistic 3D organ phantom, it is necessary to include the strain-stuffiness of tissue and a wide range of Young's modulus (Pa-MPa). Therefore, previous research is studied hydrogels with moisture content and adjustable mechanical properties similar to tissue. However, the hydrogel of a double network structure consists of a brittle crosslinked and hydrophilic polymer network, exhibiting strain-softening behavior and failing to limit the wide range of mechanical properties of various tissues. In this study, we aim to produce a 3D organ phantom applied to 3D printing using a strain-stiffness granular hydrogel. Also, we analyze the mechanisms of strain-stiffness and implement granular hydrogel with a wide range of mechanical properties. Furthermore, we intend to optimize a 3D organ phantom with a complex structure by adjusting rheological characteristics.
