Photochemical crosslinking of the GelMA precursors provides almost immediate structural stability in wet environments and at temperatures above the gelling point (cell culture conditions). However, compared to other photocurable hydrogels, GelMA -in particular in concentrations ≤ 5 wt% -suffers from inherently poor mechanical and adhesive properties, limited stretchiness, and lack of robustness against external forces . As soon as stress is applied, their structures easily fall apart, thus making damage-free transfer of hydrogel constructs quite challenging.
