Material Extrusion of the Poly(lactic acid)/HAp Nanocomposite Scaffold for Bone Tissue Applications: A Comprehensive Investigation

) of 3D-printed blended polymer materials have been assessed using Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The mechanical properties of the neat PLA and PLA/HAp blend polymer composite samples were analyzed through experimental testing, including tensile, compression, and flexural testing. It was concluded that the 12 wt % HAp blend with PLA polymer composite samples demonstrated great mechanical performance and interfacial strength characteristics. The tensile, flexural, and compression properties of PLA/12 wt % HAp were increased by 15.1, 10.05, and 13.19%, respectively, compared with neat PLA. The blended filament and fractography samples were analyzed by field emission scanning electron spectroscopy (FESEM).
