Metamaterial design for aortic aneurysm simulation using 3D printing.

Introduction: The use of three-dimensional (3D) printed anatomic models is steadily increasing in research and as a tool for clinical decision-making. The mechanical properties of polymers and metamaterials were investigated to evaluate their application in mimicking the biomechanics of the aortic vessel wall.

Methodology: Uniaxial tensile tests were performed to determine the elastic modulus, mechanical stress, and strain of 3D printed samples.
