This study proposes a manufacturing method for reproducing some physical properties of the heart by comparing the elasticity, tear resistance, and hardness of a pig heart and three-dimensional printing materials, Agilus and Tango. A Digital Force Gauge was used to analyze elastic modulus and tear resistance, whereas a Shore A hardness meter was used to measure hardness. Agilus and Tango had 10 and 5 times higher elasticity, respectively, 2 and 4 times higher tear resistance, and a higher Shore A hardness than the pig heart. In summary, the pig heart had a more similar elasticity and Shore A hardness than the Tango sample, whereas more tear resistance was similar to the Agilus sample. Therefore, we proposed elasticity and tear resistance equations that can be used to build a heart model and a conversion table for heart fabrication at various thicknesses.
