Multifactor Optimization for Development of Biocompatible and Biodegradable Feed Stock Filament of Fused Deposition Modeling

摘要

In this research work,multifactor optimization for the development of biocompatible and biodegradable composite material-based feed stock filament of fused deposition modeling(FDM)has been reported.The poly-lactic acid(PLA)has been selected as a polymer matrix with hydroxyapatite(HAp)and chitosan(CS)as filler for potential use in medical applications.The feedstock filament of PLA-HAp-CS can be used directly on FDM open-source 3D printer(without change in any hardware or software of system).The optimization results are supported by mechanical tensile testing,thermal analysis and scanning electron microscope-based photomicrographs.Finally,the feasibility of fabrication of functional prototypes for medical applications by using in-house prepared feedstock filament on the FDM has been ascertained.
