Scanning electron microscopy imaging of 3D-printed PEGDA and collagen scaffolds. Samples of PEDGA scaffolds (A–C) were freeze-dried, and samples of FRESH-printed collagen scaffolds (D–F) were prepared using ethanol and acetone dehydration followed by critical point drying. Scale bars: 100 μm (A and D), 2 μm (B, C, E, and F)
