3D printing of shear-thinning bioink. (a) Schematic showing interaction of PEGDTT and nanosilicates before and after crosslinking. Inset show printability of PEGDTT/nSi bioink. (b) Schematic of printing process through barrel, needle, and on printing bed. Peak hold experiments to mimic flow during 3D extrusion based printing. Rheological sweeps (frequency and oscillatory stress sweeps) of (c) precursor solutions and (d) crosslinked hydrogels. Note: maroon squares=PEGDTT (10% wt/vol)/nSi (4% wt/vol), red circles=PEG (10% wt/vol)/nSi (4% wt/vol), blue triangles=PEGDTT (10% wt/vol), full colored shapes indicate storage modulus (G’), open shapes indicate loss modulus (G”).
