In this Modern Era, scientist’s new developments are continuously providing solutions for many health problems. There are many ground-breaking revolutions in the medical world; 3D printing is one of them. 3D printing is using for development of precise implants of physiological and anatomical compatibilities for patients.
In case, you are the kind of individual who appreciate wearing precious stone adornments and you are looking for the replacement of your knee or hip joints or might be you will need in future, Australian researchers have some extraordinary news for you: “ostentatious medical implants of hip and knee joints”. These new artificial hip and knee joint are fabricated with diamond-coated titanium material”.
According to research report “Polycrystalline Diamond Coating of Additively Manufactured Titanium for Biomedical Applications” published in the journal ACS Applied Materials and Interfaces on 22nd of Feb, scientists from RMIT University in Melbourne have magnificently glazed a 3D-printed titanium medical implant in finely manufactured artificial diamond by utilizing special microwave heating chamber.
According to the researchers, it’s not just about influencing your innards to look fantastic, diamond covered implants will probably be better with the human body and less opportunity to develop the infection than the pure titanium implants which are normally used.
According to Kate Fox (co-author of present research), “Presently, the best quality level for therapeutic implants is made up with titanium, however, mostly titanium implants don’t connect with our bodies the way we require them too”. A senior lecturer at RMIT University said in a report. “To work around this, we have utilized diamond on 3D platforms to make a surface covering that sticks better to cells ordinarily found in vertebrates.”
In this study, researchers used Nano-diamonds (only several millionths of a centimeter long) for ultra-fine diamond coating on titanium. Nano-diamonds are synthetic diamond crystals and characteristically made by a precise detonation of a diamond. Fox Said: Nano-diamonds are producing easily in labs within few minutes at very low production cost, while natural diamonds take million decades to form inside the earth.
Rather than setting off a blast for the creation of Nano-diamond, The RMIT analysts made their engineered Nano-diamond by utilizing a machine called a chemical vapor Diamond (CVD) plasma chamber. In a CVD chamber, methane and hydrogen gases are heated up to 1000 degree Celsius and through it on a highly reactive material, consequently, plasma converted into artificial diamond crystals with specified characteristics.
In this way, the researchers turned on the microwave after putting a 3D-printed bit of titanium framework inside the CVD chamber. Once this method is completed, titanium is completely coated with diamond. So, according to the researchers: “this is an innovative way of titanium coating with diamond, which hasn’t used it before.
Hence, diamond-coated knee and hip joints have not implanted in humans for testing of its durability, compatibility and anti-infective property. But, according to FOX, she is very much confident that, diamond coated titanium implants will significantly better in compatibility and protection against infection, as compared to most commonly used titanium implants. These newly manufactured implants will decrease the bacterial attachment at the site of the implant for long period and also increase the integration between human bone and artificial implant.
According to a spokesperson of RMIT University in Melbourne (Rifai), 3D printing technology is very precise, rapid, and trustworthy. This Technology also decreases the production cost of new implants, consequently, it will be less expensive as compared to currently used implants.
The research team of RMIT University in Melbourne is very sure about the durability and therapeutic advantages of newly developed diamond coated titanium implants because they said; “it is an outstanding biomaterial which will not only enhance their wear and protection, it will also provide improved biocompatibility for 3D-printed implants”.
Currently, many diamond-coated medical products are under routine practices in our healthcare systems, such as; prosthetics, artificial heart valves, and some drug delivery systems.
