The bioink shows good printability and shape fidelity. A Viscosity measurements under continuous flow without and with hPSC-CEnCs differentiated from the used hESC line. Five replicates per bioink were measured (n = 5). B Images of printed lattices after the printing and 7 days in culture. Scale bars 2 mm. C Filament thickness (n = 6 printed structures) and D pore factors were analyzed (n = 3 printed structures) from the printed structures at day 0 and 7 to explore shape fidelity after bioprinting (* = p < 0.05). E Degradation and swelling behavior of the bioink upon time (n = 3 bioink samples)
