Computer-aided Modeling Analysis and Manufacturing Approach for Silicone Prosthesis
摘要
Abstract
Computer-aided manufacturing approach for silicone prosthesis with two-component silicone robber was studied and modeled by 3D modeling.The model was based on temperature,material parameters and geometric features for body and normal mice.The temperature difference between mold and prosthesis surface was discussed by numerical simulation on the temperature field of die and prosthesis.The feasibility of the modeling in repairing the soft tissue defect of chest wall was validated by applying phantom load from softness and fatigue life.The verification was based on finite element method.The test feasibility was based on printing material and manufacturing process.The mold were manufacturing by 3D printing.The test were carried out based on the effects ofmucosal and crosslinking reaction efficiency in die at 5,25 and 60 ℃.The effects of prosthesis softness,viscosity and stripping time were discussed by choosing different ratio of silicone and curing agent and temperature.The ratio and temperature were determined by optimizing data in the least square method and examing the regression equation prominence.The results showed that the prosthesis is affected by ratio,but not by temperature within certain range.The soft prostheses are generated when the ratio is set in 10:0.43,and at 55 ℃.关键词
