Rapid Prototyping of Tissue Engineering Vein with Valve Scaffold Model

Objective: To study the production of tissue engineering vein scaffold with valve by computer-aided designing and rapid prototyping system instead of orthodox hand-made design.Methods: The tissue engineering vein scaffold with valve was designed by 3D MAX software,then it was transferred into the STL file that could be used for compatible rapid prototyping system before the scaffold model was accomplished.Results: By this method,the tissue engineering vein scaffold with valve was designed,which was compatible with human body anatomic structure and could be directly used in rapid prototyping system.Conclusion: Computer-aided designing and rapid prototyping system in the production of tissue engineering vein scaffold with valve is a practical,rapid and accurate method that will promote the designing and industrially manufacturing of tissue engineering blood vessel scaffold.
