PEGDA and GelMA biomaterial inks
Shear-rate-dependent viscosity before crosslinking Viscosity decreased with increasing shear rate for all formulations
Thixotropic recovery before crosslinking, 1 Hz to 500 Hz to 1 Hz Viscosity dropped instantaneously at high shear and recovered to ~100 % of its initial value after high shear was removed
Oscillatory rheology before crosslinking Storage modulus G′ exceeded loss modulus G″ for all formulations
Storage and compression moduli after crosslinking, PEGDA 5 % G′ approximately 1.5 kPa; E 5 kPa
Storage and compression moduli after crosslinking, PEGDA 10 % G′ 8 kPa; E 50 kPa
Storage and compression moduli after crosslinking, GelMA 3 % G′ 1 kPa; E 3 kPa
Storage and compression moduli after crosslinking, GelMA 7 % G′ 5 kPa; E 12 kPa
