particles, which were absent from the surfaces of fibers alginate ratio in the G/A microparticles, demonstrating
printed in the support bath with G/A microparticles that the addition of alginate led to better resolution
(Figure 4a). The fiber widths decreased with increasing (Figure 4b).

Figure 4. Influence of printing parameters on fiber formation. (a) Morphology and (b) widths of printed fibers obtained in the support baths containing
gelatin/alginate (G/A) microparticles with different alginate concentrations. (c) Compression modulus of cubic structures printed in support baths
containing G/A microparticles with different alginate concentrations. (d) Effect of the support bath concentration on the fiber width and morphology. (e)
Effect of nozzle size on the fiber width and morphology. (f) Effects of the extrusion pressure and nozzle moving speed on the fiber morphology (f1) and
fiber width (f2). Scale bars: 0.25 mm (a); 2 mm (f1).
