Geometric characterization of NGG-PCL 3D-printed membranes. a Height and length path of the first and second layers during 3D printing. b PCL membranes: lateral view showing two layers (T) and diameter (d) of the filaments with 396 ± 74 μm. c PCL membrane dorsal view showing the pores with 312 ± 58 μm of length and 300 ± 51 μm of height. d 3D-printed PCL membrane macroscopic view. e Internal face of PCL membrane (scale bar: 2.0 mm). f Scanning microscopy electronic images of 3D-printed PCL membranes with different pores, filament lengths, and deposition of two layers (scale bar: 500 μm). g NGC cross sectional view after assembly (scale bar: 2.0 mm). h NGC external surface view (scale bar 2.0 mm). i Measures of geometric parameters from PCL membranes (n = 5). Values are represented as mean ± SEM
