There is a versatile bio-ink consisting of a 4-arm PEG based polymer with distal maleimide derivatives as the main ink component, and a bis-thiol species as the activator that can cross-link the polymer to form a hydrogel in less than a second. Rapid gelation makes the polymer system compatible with 3D bioprinting.
