Bone fracture due to internal or external factors is one of the most common diseases in today's orthopedic society. One of the techniques to solve these problems is to use artificial porous bone grafts made by 3D printers and the Freeze-Drying (FD) techniques. In this study, a shapeless porous scaffold was first fabricated using Fused Deposition Modeling (FDM) with the electroconductive filament. The printed scaffold is inserted into the alginate solution composed of Magnetite Nanoparticles (MNPs) containing 0, 10, 20, and 30 wt% baghdadite nanoparticles. Then, the four samples are coated using an FD technique at −45 °C and 0.01 m bar. The mechanical and biological properties are investigated using compressive strength and Simulated Body Fluid (SBF) test. The samples are analyzed using Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) analysis to evaluate the morphology and phase of the …
