Figure 3.

Tensile Young’s modulus of fiber-aligned scaffolds produced at varying speeds tested parallel (presumed fiber direction, ∥) and perpendicular (⊥) to the direction of shaft rotation. For each condition, the Young’s modulus was derived from the linear region of the stress-strain curve. A total of six to eight samples were tested from two different scaffold production runs (*p<0.05 vs. parallel at the same speed, **p<0.05 vs. parallel fibers produced at different speeds).
