Abstract: Described is a biomaterial/carbonate-based ink that comprises a biopolymer-based mixture and bioceramics. The photo- and ionic crosslinkable biopolymer mixture comprises polysaccharide and gelatin-based materials. The bioceramics comprises an apatite and a carbonate. The biopolymer-based mixture is mixed with the bioceramics to form the ink. The ink is capable of being applied under wet or dry conditions. The wet condition is seawater or water or other aqueous solution. The ink is capable to instantly get solidified, when UV or blue light is applied in the presence of the ionic components found in seawater. After photo- or ionic crosslinking, this ink is stable for months.
