3D The method for preparing bio-ink and its application on 3D printing

摘要

The present invention relates to a bio ink composition for a 3D printer, a production method thereof, and a biomaterial using the same, and is a bio ink composition for a two-pack type 3D printer comprising (A) a first liquid and (B) (I) the first liquid (A) comprises a first biopolymer into which a first chemical functional group is introduced, and (B) the second liquid comprises a second biopolymer into which a second chemical functional group is introduced; Or (ii) the first liquid comprises (A) the first biopolymer into which the first electrostatic functional group is introduced, and (B) the second liquid comprises the second biopolymer into which the second electrostatic functional group is introduced In addition, The first chemical functional group and the second chemical functional group are chemically reacted to each other to be bonded and the first electrostatic functional group and the second electrostatic functional group are physically bonded to each other by electrostatic attraction .
