Beschreibung
Zusammenfassung:	The present invention relates to a three-dimensional (3D) printing system for manufacturing an artificial blood vessel and a method for manufacturing an artificial blood vessel using the same, wherein a cylindrical support having a hollow 3D porous structure including a thermoplastic polymer is manufactured and vertically fixed, and a hydrogel divided into at least two sections is discharged into the support, thereby maintaining the structure and shape constantly even after printing and manufacturing an artificial blood vessel having a hollow multilayered structure. The 3D printing system for manufacturing an artificial blood vessel comprises: a rotatable support manufacturing unit which forms a hollow cylindrical support having a 3D porous structure by discharging a polymer to the outer circumference thereof through a first head; a first head which forms a hollow cylindrical support having a 3D porous structure by discharging a polymer to the support manufacturing unit; a support vertically holding the hollow cylindrical support manufactured through the first head; and a second head which discharges a hydrogel, divided into at least two sections, into the cylindrical support vertically held and fixed to the support.
