AI Technical Summary

Problems solved by technology

When the ink has a low viscosity, it is easy to deform the shape of the molded object and become unstable because it is printed on the substrate in a liquid state.
In addition, when the ink has a high viscosity, although it is suitable for maintaining the shape on the substrate, it requires a high pressure when ejected from the nozzle, and there is a problem that the survival rate of the cells decreases.

preparation example Construction

[0061] The preparation method for preparing the silk nanofiber dispersion is not particularly limited, and a preparation method in which silk nanofibers are added to a solvent and dispersed by a conventionally known method can be mentioned.

[0062] The solvent is not particularly limited as long as it can disperse silk nanofibers, and examples thereof include water, an aqueous solution substantially isotonic with body fluids, a mixture of water and an organic solvent, and the like. Among them, water is preferable from the viewpoint of excellent safety. That is, as the silk nanofiber dispersion liquid, it is preferable to use an aqueous silk nanofiber dispersion liquid. In addition, from the viewpoint of further improving the viability of animal cells in the ink for a 3D printing system of the present invention, an aqueous solution that is substantially isotonic with body fluids is preferable.

[0063] The pH of the silk nanofiber dispersion liquid is preferably 2.0 to 14.0, ...

Abstract

Provided is an ink for a 3D printing system having excellent pseudoplasticity. The ink for a 3D printing system includes: silk nanofibers; and a natural polymer and / or a synthetic polymer.

Description

technical field [0001] The invention relates to an ink used in a 3D printing system. Background technique [0002] In recent years, three-dimensional cell culture technologies aimed at various fields such as regenerative medicine have been developed. Among them, 3D bioprinting has attracted attention because it can reproduce complex tissues. [0003] 3D bioprinting is a technique in which a cell-containing gel material is ejected in layers to a target site, fixed and stacked while gelling, and a three-dimensional gel structure in which cells are three-dimensionally arranged is produced. The density and arrangement of cells can be controlled with high precision using a computer. [0004] In the printing technology, there are mainly three types: inkjet type, laser type and extrusion type (Non-Patent Document 1), among which the viscosity of the ink is an important parameter in the extrusion type 3D printing. When the ink has a low viscosity, since it is printed on the substr...
