Abstract:
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.

Claim (Index 1):
A method for producing a gelatin structure, the method comprising:\n a biocompatible material structure forming step of jetting a liquid obtained by melting a biocompatible material that is solid at normal temperature and is water-soluble and thermoplastic, in a droplet state through a nozzle unit, stacking the biocompatible material on a liquid landing surface, which is a surface of a substrate where liquid droplets land, and forming a biocompatible material structure having a three-dimensional structure formed from the biocompatible material; a coating film forming step of forming a coating film containing gelatin, which coats the surface of the biocompatible material structure formed by the biocompatible material structure forming step; a gelatin structure forming step of attaching gelatin on the periphery of the biocompatible material structure having the surface coated with the coating film formed by the coating film forming step, and forming a gelatin structure; a shaping step of shaping the gelatin structure formed by the gelatin structure forming step into a predetermined shape; and a dissolving step of subjecting the biocompatible material structure to the action of water to dissolve at least a portion of the biocompatible material structure, and thereby transferring a shape of the biocompatible material structure to an interior of the gelatin structure, wherein in the biocompatible material structure forming step, the biocompatible material structure is formed using a first biocompatible material having a molecular weight distribution that can be adjusted to a viscosity range enabling jetting of the biocompatible material alone in a temperature range in which the temperature of the biocompatible material jetted out through the nozzle unit can be adjusted, the first biocompatible material having a viscosity of from 100 milliPascal\u00b7second to 5,000 milliPascal\u00b7second, or a third biocompatible material obtained by mixing the first biocompatible material with a second biocompatible material having a molecular weight distribution that cannot be adjusted to a viscosity range enabling jetting of the biocompatible material alone in a temperature range in which the temperature of the biocompatible material jetted out through the nozzle unit can be adjusted, the third biocompatible material having a viscosity of from 100 milliPascal\u00b7second to 10,000 milliPascal\u00b7second.
