The present invention relates to a chitosan hydrogel composition comprising chitosan, glycerol, and a phosphate group, wherein the chitosan is crosslinked by glycerol, a phosphate group, or a combination thereof. The chitosan hydrogel composition enables temperature control for inducing a liquid-state composition into a gel state according to the content ratio of a phosphate group and glycerol, and since the concentration of gelatin affects the printing characteristics, strength, and the like, can be used as ink for 3D printers. 本公开涉及一种包括壳聚糖、甘油和磷酸基团的壳聚糖水凝胶组合物，其中所述壳聚糖被甘油，磷酸基团或其组合交联。可以对所述壳聚糖水凝胶组合物进行温度控制，以使根据磷酸基团和甘油的含量比，将液态组合物诱导成凝胶态，并且因明胶的浓度影响打印特性和强度等，因此可以用作3D打印墨水。
