Figure 9.

Multi-angle depiction of 3D-printed (A0–A5) inks by means of micro-CT analysis: (i) close-up on basic square lattice of the 3D model; (ii) Frontal view of four-square units of the print; (iii) Side view of the object surfaces; (iv) Lateral cross-section illustrating inner architecture of the freeze-dried material. In the i. and iv. images, the scale unit is 500 µm. The blue and red lines mark the inner and outer extremities of the printing unit while the violet-dotted perimeters highlight the porosity of the printed objects, from the cross-sectional view.
