Abstract

This paper presents a novel continuous material deposition path planning methodology for hollowed scaffold fabrication in tissue engineering. Functionally gradient porosity architecture has been achieved with the desired pore size by combining two consecutive slices. Modeling of the first layer with equal area sub-regions from ruling line represent the zigzag pattern ensures the biological requirement of the scaffold and the consecutive circular pattern layer mainly enforces the designed porosity of the scaffold. Finally, continuous and interconnected optimized tool-path has been generated as an input for the solid free form fabrication process. Three-dimensional layers formed by the proposed tool path plan vary the pore size and hence the porosity based on the required biological properties. Several examples demonstrate the proposed methodology along with illustrative results.
