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 polylactic 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.
