Biodegradable Scaffolds for Urethra Tissue Engineering Based on 3D Printing

Tissue engineering scaffolds are used to repair urethra universally, whereas few of those methods could fit the specific shape of the patient's lesion. Here a selection of biodegradable polymers were made, and then an economic, biodegradable, modified material PLGA/PCL/TEC 70:30:6 with good biocompatibility and mechanical properties was prepared. A method for customized tissue engineering scaffolds based on 3D printing technology was...
