Mechanical assessment of patterned scaffolds with three different layer numbers. (a) Typical stress-strain curves for different layer scaffolds, (b) Failure load, (c) Elastic modulus, (d) Toughness (e) Failure stress and (f) Stiffness of 6 layer scaffold is more than 3 fold greater than the 2 layer scaffolds. The horizontal line indicates significant difference (p <0.05).
