A method for producing a gelatin structure, the method including forming a three-dimensional structure having a hollow part using gelatin as a material, is provided, and a gelatin structure production system is provided. A biocompatible material structure having a three-dimensional structure is formed by jetting a liquid obtained by melting a biocompatible material that is solid at normal temperature and is water-soluble and thermoplastic, through a nozzle unit; and stacking the biocompatible material on a liquid landing surface of a substrate. The surface of the biocompatible material structure is coated with a coating film containing gelatin, gelatin is attached to the periphery of the biocompatible material structure to form a gelatin structure, the gelatin structure is shaped, the biocompatible material structure is dissolved, and the shape of the biocompatible material structure is transferred to the interior of the gelatin structure. For the formation of the biocompatible material structure, a first biocompatible material, or a third biocompatible material obtained by mixing a second biocompatible material with the first biocompatible material, is used. |
