a Simplified mechanical model of springs to calculate stiffness of scaffolds. Untreated specimens will report only material’s stiffness k1. After treatment, scaffolds will increase their resistance as they also host for bone cellular matrix stiffness k2. This model of springs will allow us to calculate an equivalent-stiffness parameter ke. b Testing anisotropy of 3D-printed scaffolds. Different axes of compression are tested as 3D printing technology introduces anisotropy characteristics to scaffolds since they are being manufactured layer by layer
