Images and characterization of 3D cell-laden hydrogel scaffolds of po250 and po350 fabricated by OCT IFBP method. (A1A6) po250 and (B1B6) po350; (A1,B1) images; (A2,B2) micrographs showing the surface; (A3,B3) OCT cross-sectional images with a depth of up to 3.0 mm; (A4,B4) OCT en-face image; (A5,B5) 3D rendering of OCT images; (A6,B6) reconstruction of pore networks; (A7,B7) reconstruction of material distribution displaying a more uniform pore and strut distribution than the first run; (C1) average PS; (C2) StS; (C3) VP; (C4) Sa; (C5) and VP obtained from OCT images compared to the corresponding predicted values. Error bars represent the intra-batch variation. Δ Represents the discrepancy between the average as-printed and predictive value.
