Mechanical and structural properties of the scaffolds. (A) Three-dimension (3D) design model (a1) with target filament size and layer thickness, and the finite element analysis (FEA) result (a2) with 3D view (up) and the cross-sectional view (down). (B) three-dimensional extrusion-based bioprinter-associated optical coherence tomography (3D P-OCT) model before feedback (b1) with target filament size and layer thickness, and FEA result (b2) with 3D view (up) and the cross-sectional view (down). (C) 3D P-OCT model after feedback (c1) with target filament size and layer thickness, and FEA result (c2) with 3D view (up) and the cross-sectional view (down). (D) Volume porosity (VP) and porosity connectivity (PC) of the scaffold before (left) and after (right) feedback. (E) Compressive curves corresponding to three models in (A-C).
