(A) Comparison between conventional extrusion-based bioprinting and novel CEW process with respective differences in cell distribution and process resolution. (B) Schematic of the developed gelatin and silk fibroin bioink compositions with their respective light photo-cross-linking mechanism. Scheme illustrates the visible light-initiated orthogonal cross-linking of (i) gelnor with a PEG thiol cross-linker and (ii) silk fibroin, in the presence of ruthenium and SPS. Gelnor and silk bioinks are compatible with both extrusion-based printing and CEW.
