| Abstract Scope |
The customized implants (cup, dome and prosthetic head) of Ti64, were designed and fabricated using the extrusion 3D printing technique. The binder elimination was performed using a thermal cycle with a heating rate of 10°C/min up to 500 °C during one hour. Next, the sintering process was carried out at 1200 °C with one hour of permanence obtaining a relative density of 80% in a horizontal furnace under argon atmosphere. After sintering, the presence of fissures was observed, which were analyzed by means of X-ray microtomography and scanning electron microscopy. It was determined that fissures are consequence of the stresses generated during densification due to the complex shape of parts. The microstructure shows the presence of the alpha and beta phases, which are responsible for the good corrosion resistance. Finally, permeability was assessed by numerical simulations ensuring that the passage of body fluids throughout the bone implant will be able. |
