Abstract: “Polylactic acid (PLA) based polymer composites containing titanium dioxide (TiO2), synthetic hydroxy apatite (HA) and natural hydroxy apatite (nHA) have been developed for biomedical applications. These extruded composite materials were printed using Fused Deposition Modeling (FDM). 3D printing parameters and mechanical properties were characterized. According to the tensile dimensional accuracy analysis; Maximum tensile strength (59.85 N/mm2) and maximum elongation to break (1.62 mm) were obtained from a mixture of 98% PLA, 1% nHA and 1% TiO2 at 220°C printing temperature.”
