Abstract: The present invention relates to the field of materials science, the field of nanomaterials, and the field of biomedical engineering, and in particular to an inorganic non-metallic nanoparticle-assembled hydrogel material and an application thereof inl additive manufacturing technology. The hydrogel material is assembled from inorganic non-metallic particles, so as to form a hydrogel network; the size of the inorganic non-metallic particles ranges from 10 nm to 20 um; the inorganic non-metallic particles account for 2-80 wt % of the total mass of hydrogel; and the hydrogel network has microscopic pores having a pore size ranging from 0.1 um to 30 um. The inorganic non-metallic particles are assembled into a hydrogel material by an electrostatic assembly method or a hydrophobic action assembly method or a magnetic action assembly method. The hydrogel material is additively manufactured to obtain a gel scaffold which is used as a bone repair scaffold or a cartilage repair scaffold. The hydrogel material of the present invention is directly applied to inorganic non-metallic additive manufacturing technology, without using an additive or a cross-linking agent.
