Analysis for biodegradable polymeric scaffold of tissue engineering on precision injection molding

Precision injection molding is the most important technology in Bio-MEMS/NEMS industry for the necessary of scale, velocity and cost by the development of Bio-MEMS/NEMS industry and the innovation of Bio-MEMS/NEMS industry. It has the advantage of low cost, low interface and small volume in Bio-MEMS/NEMS industry. This paper emphasizes the analysis for three dimension biodegradable polymeric scaffold on precision injection molding. The finite element method in a three-dimensional inertia-free, incompressible flow is presented. A control volume scheme with a fixed finite element mesh is employed to predict flow front advancement. The plastic material of scaffold is used for PLA material. The results show that the short shot on the filling stage of precision injection molding. The results also indicate the processing window and optimal processing for three dimension biodegradable polymeric scaffold on precision injection molding.
