3D Printing is no longer news although I suspect most people haven’t heard of it yet. In fact there is a company within a couple of km of my office in Albany already successfully offering a variety of 3D printing services, incidentally called 3D Print. Another Aucklander, well known internationally in the 3D printing with RepRap is Vik Oliver, seen here with one of his machines.
When I heard that Richie McCaw was injured and after surgery was going to miss around 6 matches after having a titanium screw in his foot, my first reaction was, as most Kiwis, just what we need in Rugby World Cup year as he is such an amazing skipper and we want him there leading the All Blacks. Then I thought about so many other sports people who suffer injuries all the time given that they are putting their bodies on the line professionally.
Imagine a technology that rebuilds or repairs body tissue, bones, ligaments, even organs in vivo, using micro surgery techniques that mean people recover far more quickly, naturally and potentially therefore stronger than before.
Using the same types of technologies as conventional 3D printing, it will soon be possible to pattern and assemble, layer by layer, functioning living tissue, as well as non living substitutes such as ceramic and titanium according to Vladimir Mironov, an associate professor and director of the Advanced Tissue Biofabrication Center at the Department of Regenerative Medicine and Cell Biology, Medical University of South Carolina. He is also currently making waves about growing in vitro meat, something I have previously blogged about.
So this is a relatively new technology and I don’t know that it has been tested on humans yet, but the technology is already commercially available from companies such as envisionTEC.
Imagine the good this technology could do for people with problems from injuries, burns, through to the huge numbers of people who die for lack of organs for transplant.
The following video shows how bioprinters will be used in the long term. The technology will also be used to create human tissues which can be used for drug testing instead of using animals.
Of course if tissues and organs are made using material from the host, we can eliminate problems such as donor organ rejection.
