Figure 3. Analysis of 3D-printed PCL scaffolds with varying offsets. (A) The 1 mm spacing polycaprolactone (PCL) scaffold with 0, 1, and 2 offset(s). Scale
bar: 0.5 mm. (B) Theoretical effect of offset(s) on porosity. (C) Theoretical effect of offset(s) on pore size. (D) Compressive properties of “1 mm spacing, 1
offset” and “2 mm spacing, 1 offset” scaffolds composed of “straight” or “circumferential + radial” fibers.* denotes significant difference between region in
each layer (p < 0.05). # denotes significant difference between same region in different layers (p < 0.05).
