Nowadays, metallic bone replacement is in high demand due to different issues, like sicknesses and accidents. Thus, implants are fabricated with tailored properties microstructure for long-term use the human body. To improve such implants, 3D printing most promising technique. Therefore, this work aims evaluate fabrication of porous materials by extrusion Ti6Al4V. Cylindrical samples were from pellets metal injection molding Ti6Al4V powders, creating hexagonal channels three sizes. The densification kinetics was evaluated dilatometry tests, which enabled following during sintering cycle. Subsequently, characterized scanning electron microscopy X-ray computed tomography analyze their microstructure. Compression tests mechanical strength sintered samples. It found that shape better defined as channel size increases. results show similar behavior each sizes sintering; however, greater obtained decreases. Additionally, microporosity at particle level, completely interconnected, ensuring passage fluids through entire sample. On other hand, increases, Young's modulus yield considerably reduced. main conclusion parts two scales porosity can be designed process.
