Journal Article
Automatic Algorithm for Generating Complex Polyhedral Scaffold Structures for Tissue Engineering
2004
Overview
In this article, an approach for tissue-engineering (TE) scaffold fabrication by way of integrating computer-based medical imaging, computer graphics, data manipulation techniques, computer-aided design
(CAD), and rapid prototyping (RP) technologies is introduced. The aim is to provide a generic solution for the production of scaffolds that can potentially meet the diverse requirements of TE applications.
In the work presented, a novel parametric library of open polyhedral unit cells is developed to assist the user in designing the microarchitecture of the scaffold according to the requirements of its final
TE application. Once an open polyhedral unit cell design is selected and sized, a specially developed algorithm is employed to assemble the microarchitecture of the scaffold while adhering to the external
geometry of the patient's anatomy generated from medical imaging data. RP fabrication techniques are then employed to build the scaffolds according to the CAD-generated designs. The combined application
of such technologies promises unprecedented scaffold qualities with spatially and anatomically accurate three-dimensional forms as well as highly consistent and reproducible microarchitectures. The integrated
system also has great potential in providing new cost-effective and rapid solutions to customized made-to-order TE scaffold production.
