Impact of FFT and testing angle on the peak stress (A), peak strain (B) and modulus of elasticity (C). From the peak stress data we conclude: (i) onset of anisotropy begins at FFT values greater than 0.05 units, (ii) scaffolds tested in the transverse orientation are isotropic with scaffolds tested in the perpendicular orientation and (iii) peak stress of longitudinal samples changes incrementally in 1–2 FFT alignment units. Asterisks in A and B indicate the onset of anisotropic properties within the longitudinal samples and the divergence of these samples from the perpendicular and longitudinal test groups. See Fig. 6 for a complete breakdown of the statistical analysis. All data are ±SE.
