Biomimetic Porous Metal Implants Manufactured by 3D Printing and Bioactive Ceramic Coating
3D printed porous Ti-6Al-4V(Ti64)implants were fabricated by selective laser melting(SLM).And the outer surface of porous Ti-6Al-4V implant was modified by a bioactive ceramic coating.The microstructure of selective laser melted implant and bioactive ceramic coatedimplant are evaluated byfield emission scanning electron microscopy(FE-SEM)and Energy-dispersive X-ray spectroscopy(EDS).The experimental results show that particle size distribution of Ti-6Al-4V alloy powder for SLM process is in the range between 10μm to 60μm.A porous structure with a porosity of about 60%is formed by the 3D printing process.After chemical surface modification,the porous Ti-6Al-4Vspecimen formed a dense and uniform bonelike apatite layer on the metal surface in simulated body fluid(SBF)solution.The thickness of apatite layer is about 1μm.The present apatitecoating is therefore expected to allow the use of bioactive Ti-6Al-4V implant as artificial bones to enhance bone growth.
