Zusammenfassung: | The present invention relates to a method for manufacturing a light-sensitive inorganic nanoparticle ink and a method for printing a 3D structure using the same. According to one aspect of the present invention, the method for manufacturing a light-sensitive inorganic nanoparticle ink comprises the steps of: manufacturing nanoparticles capped with an organic material; manufacturing a nanoparticle dispersion by dispersing the nanoparticles capped with the organic material in a non-polar solvent; manufacturing an inorganic ligand solution by dissolving the inorganic ligand in a polar solvent; stirring the mixture of the nanoparticle dispersion and the inorganic ligand solution to obtain nanoparticles capped with an inorganic ligand; preparing an all-inorganic nanoparticle solution by dispersing the nanoparticles capped with the inorganic ligand in a polar solvent; and mixing the inorganic nanoparticle solution and a photoacid generator. The purpose of the present invention is to be applicable to optical-based 3D printing technology and suitable for multi-field applications.
