Focusing on the tensile elastic modulus of the scaffold, as depicted in Figure , it can be noticed that the 3D printed structure exhibited a crucial impact on the scaffold's ultimate strength, yielding values of 15 to 18 MPa at a 30% elongation threshold. Furthermore, our investigation revealed the influence of polymer composition on scaffold performance. It can be seen from Figure that the addition of 5% PEG soft segments to the copolymers reduced the ultimate strength of the scaffold from 18 to 14 MPa. However, this addition led to an increase in elongation from 225% to 250%, resulting in a slightly more flexible scaffold. Figure also provides a visual representation of the modulus and elongation comparison between tubular hierarchical structures made of PBS-DLS 70-30 with and without PEG. The data underscores that the inclusion of 5% PEG into the PBS-DLS copolymers had a discernible effect on the modulus of the scaffold, slightly increasing from 55 MPa to 60 MPa. In comparison to similar studies, bilayer biodegradable elastomeric PCL scaffolds exhibited an elastic modulus of 1.4 ± 0.4 MPa and an ultimate tensile stress of 8.3 ± 1.7 MPa . Comparing our results to the mechanical properties of the human internal mammary artery with an elastic modulus ranging from 8 to 16 MPa, ultimate stress from 4 to 6 MPa, and strain at failure between 60% and 140% -showcases the success of fabrication efforts. Similarly, a small-diameter polyurethane-based vascular graft reinforced with a knitted fabric showed higher strength than human arteries, offering a balance of high strength and elasticity through its multilayer structure, which mirrors natural artery architecture .
