Mechanical Properties of 3D Printed Resorbable Material for Manufacturing of Vascular Replacements

Popis výsledku v původním jazyce

Modern additive manufacturing methods offer the ability to achieve high geometric complexity, allowing for the production of tubular implants with intricate anatomical details that were previously unattainable. Specifically, the manufacturing process enables the accurate fabrication of structures such as the aortic arch and its branches, which display significant inter-individual geometric variability. In this study, we investigate the mechanical properties of a 3D-printed material composed of polylactic acid (PLA) and polyhydroxybutyrate (PHB), which holds potential for additive manufacturing of such implants. The results of uniaxial tensile tests conducted on PLA-PHB are compared with the mechanical behavior of GORE tubes, currently utilized as vascular grafts in clinical practice. Our findings reveal that, within the range of linear elasticity, the mechanical response of PLA-PHB strips closely resembles that of circumferentially cut GORE-TEX vascular graft strips. Conversely, longitudinally oriented GORE-TEX strips exhibit greater compliance compared to the 3D-printed PLA-PHB material.
