Figure 2.

Highly sophisticated CPC scaffold structures via 3D plotting. Stereomicroscopic images of CPC scaffolds plotted with 15° (a), 45° (b), 60° (c) and 90° (d) configurations (change in orientation relative to the layer underneath). Design and printing of a CPC-hydrogel biphasic scaffold: model of biphasic scaffolds with CPC (white) and a growth factor-loaded hydrogel (red) (e); the printed scaffold (f); 3D reconstructions from micro-CT data of the biphasic scaffold (g, h). CPC is grayish white. Alginate-gellan hydrogel is blue. (Adapted from Ahlfeld et al.⁶⁴ with permission.)
