From: 3D printed mesh reinforcements enhance the mechanical properties of electrospun scaffolds
Mechanical testing confirms greater tensile strength of reinforced scaffolds as compared with unmodified electrospun scaffolds. Load to fail testing was performed on unmodified electrospun scaffolds (control) or scaffolds with either the 6 mm or 8 mm 3D-printed mesh reinforcement (n = 7 scaffolds per group). Scaffolds were evaluated for: a tensile strength, b elastic modulus, and c tensile strain. In comparison with unmodified scaffolds, the reinforced scaffolds exhibited enhanced overall strength and rigidity. d Representative plot of stress vs. strain. * denotes p < 0.05 relative to control. # denotes p < 0.05 relative to the 8 mm reinforced scaffold
