▎ 摘　　要

NOVELTY - Bio-ink composition comprises fine-grained cartilage component, microparticulated polymers and biocompatible polymer. USE - Bio-ink composition used for 3-dimensional printing. ADVANTAGE - The bio-ink composition induces cartilage tissue to be safely and effectively regenerated, improves viscoelasticity and strength, and solves phenomenon that shape disappears without able to laminate 2-3 mm or more during conventional 3D printing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing bio-ink composition for 3D printing, which involves: (A) freeze-drying finely divided cartilage component; (B) pulverizing freeze-dried cartilage; and (C) sieving pulverized cartilage.
