abstract

The Fused Deposition Modeling (FDM) technology can be successfully used to manufacture biodegradable polymeric scaffolds for tissue reconstruction in case of critical size bone damages. Carbon nanotubes (CNTs) are able to mimic the extracellular matrix and their addition can improve the mechanical and electrical properties of polymers. In this way, the scaffolds are more likely to match the host bone properties and the cell adhesion, differentiation and proliferation can be enhanced. In this paper scaffold-like specimens, manufactured by FDM technology, are tested to evaluate the conductivity increase in PLA/CNT composite compared to pure PLA (polylactid acid).
