The bioprinting window for gelMA and gellan gum hydrogels (bordered by red line) and examples for printed constructs. A) Low polymer concentrations were too fluid to form a defined filament at 15 - 37°C (white), while high polymer concentrations formed too strong physical gels at 37°C to allow mixing with cells (dark grey). The middle range of polymer concentrations was suitable for bioprinting (green) although different optimal print temperatures were found (numbers in °C, for some formulations no optimal (cell-friendly) temperature could be found (N/A)). B) Image of a 3/1% gelMA/gellan construct printed at 30°C. C) Image of a 10/0.5% gelMA/gellan construct printed at 28°C. D) magnification of figure B. Scale bars represent 2 mm.
