Figure 5

Optical images of dry (top row) and wet (bottom row) GGMA4 (left), GGMA4/BSF-Eumel (middle) and GGMA4/HAp30 (right) 3D-printed scaffolds with 45% infill (scale bar: 2 mm): (a) top view and (b) lateral view. (c) SEM micrographs of GGMA4 (left), GGMA4/BSF-Eumel (middle) and GGMA4/HAp30 (right) 3D-printed scaffolds with 45% infill (Mag. 50× and scale bar: 3 mm (top row); Mag. 2000× and scale bar: 50 μm (bottom row)). (d) Swelling ratio (Q, expressed as a dimensionless ratio) and (e) relative weight (WR, expressed as a dimensionless ratio) of GGMA4, GGMA4/BSF-Eumel and GGMA4/HAp30 3D-printed scaffolds as function of time in DMEM-HG supplemented with antibiotics up to 28 days in physiological conditions (pH 7.4 at 37 °C).
