Abstract: |
The method of complicated tubular netted tissue engineering rack forming technology based on core dissolving technique belongs to the field of tissue engineering rack manufacturing technology. The technological process includes first designing 3D model of rack and rack core; making rack core with water soluble material without biotoxicity through fast laminated formation; compounding solution of biocompatible material with proper amount of pore creating agent and coating the solution onto the rack core; air drying, soaking in distilled water to dissolve out rack core and pore creating agent, taking out and volatilizing water and coating different forming material with or without pore creating agent successively to form the tubular netted rack with complicated spatial structure, different material gradient and different pore gradient. |
