The 3D printability of cold-water fish gelatin used as co-initiating species for the crosslinking of PEGDA monomers in presence of camphorquinone (through a Norrish II reaction) is evaluated. The 3D digital light processing leads to the creation of biocompatible printed structures able to support cell viability and proliferation.
