Mechanical properties of both uniform and gradient scaffolds. a) Scaffold compressive yield strength and b) compressive modulus as a function of volume fraction, where ε = porosity and both axes are on a logarithmic scale (base 10). Predicted values for dotted line (Theory) a) slope = 1.5 and b) = 2, follow a power law relationship of an isotropic cubic cell. Experimental values follow a best fit power law relationship as stated in Table 4.
