Structural characterization of dual porosity scaffolds. a) Scanning electron microscopy (SEM) images of scaffolds prepared from P(l)LCL and P(l,d)LCL copolymers as dual porosity scaffolds starting from gels of 5% and 7% polymer concentration and scaffolds fabricated via fused deposition modeling, coded as 100%. Images are shown (left to right) as the overall appearance of the scaffold from the top, a magnification of the scaffold's surface, the overall scaffold cross section and a magnification of the cross section. b) Images of P(l)LCL and P(l,d)LCL dual porosity scaffolds at 5% and 7% gel concentrations obtained with µCT and frequency plots of the pore diameters as measured by SEM. c) Compressive Young's moduli of dual porosity scaffolds at 5% and 7% polymer concentration and of 100% scaffolds. Statistical significance was calculated from one‐way ANOVA with Tukey's multiple comparison test, n = 3, F(DFn, DFd), F(5, 12) = 35,39. P‐adjusted (****) p < 0.0001, (***) p < 0.001, (**) p < 0.01, and (*) p < 0.1.
