Figure 4. Extrusion bioprinting of GelMA-Tyr bioinks.

Figure 4

A) Rheological profile of GelMA and GelMA-Tyr in response to shear rate. B) Cell viability of ACPCs bioprinted within GelMA and GelMA-Tyr constructs. Macroscopic images of extrusion bioprinted C) GelMA and D) GelMA-Tyr constructs, together with a representative image of the filament collapse assay, showing the ability of the printed struts to bridge gaps of 4 mm without noticeable deformation, and up to 16 mm while experiencing sagging. Scale bar = 1 mm.
