Exploring SVM Rapid Prototyping in Scaffold Fabrication

Abstract

Presented in this paper is an initial effort toward medical application of Selective Vacuum Manufacturing (SVM), a simple rapid prototyping technique that is being developed. This preliminary study explored the possibility of applying SVM technique to build scaffold, a structure supporting tissue formation. Three different laydown patterns: solid, 0o/90o, and zigzag were successfully used for fabricating scaffolds from Poly-lactic acid (PLA) powder, and all the built scaffolds provide high porosity which is important for tissue growth. The result suggests further study on improving the mechanical strength of the scaffold, preventing contamination, and scaling down the size of the scaffold
