(a) Schematic of printing needle to show the sections used for analysis; (b) homogeneity as calculated by the ratio of viscosities η, nStart, nEnd = 3, mean ± standard error; (c) shape fidelity determined by the ratio of strand widths d of plotted scaffolds, nStart, nEnd = 60, mean ± standard deviation; (d) plotted four-layered scaffolds fabricated with the plasma-alg-mc bioink model from start and end of cartridge. Scale bars: 2 mm.
