Beschreibung
Zusammenfassung:	The invention relates to a modified 3D printing auricular cartilage tissue engineering scaffold as well as a modification preparation method and application thereof. The modified scaffold is obtained by modifying a 3D printing mechanical bionic auricular cartilage tissue engineering scaffold disclosed by the Chinese patent CN202011300830.8 through compounding of natural polymer materials, and the modified scaffold has a porous and frameless structure, has mechanical properties similar to those of human natural auricular cartilage tissues, has good biocompatibility and biodegradability, and can be applied to the field of artificial auricular cartilage tissue engineering, such as artificial auricular cartilage tissue engineering, artificial auricular cartilage tissue engineering, artificial auricular cartilage tissue engineering, artificial auricular cartilage tissue engineering and artificial auricular cartilage tissue engineering. The cell inoculation rate and cell compatibility of the 3D printing auricular c
