Penn State Creates 3D Printed Cartilage

When I was in high school, I took a 3D art class where we would make and then print 3D figures and models. I never thought that I would hear that one day human cartilage could be 3D printed to help humans and that my school, Penn State would be the ones to break the barrier. The purpose behind this new technology is to  help replace damaged tissue with new 3D printed tissue that is from the same person. An article on news.psu.edu explains the history and the significance of 3D printing and how it will change the medical community.

Penn State scientists 3D printed cartilage by creating large scale scaffold less tissues which are tiny tubes of algae that are between .003 – .005 inches in diameter. Then the tubes are inserted with the cartilage cells. These cells take approximately a week to grow. After they are grown, they are taken and removed from the tubes and the only thing that remains are thin strands of cartilage. Instead of ink, those strands are then used to 3D print almost anything.

This new 3D printed cartilage gives a lot of opportunity for medical advances. Eventually this technology is going to be applied to human cartilage. The fact that it is from the same person allows patients to not have to worry about finding a match. This technology allows patients to be their own source of tissue regeneration. Stem cells could then be developed into cartilage cells.

    This really caught my attention, because, since 3D printing first became a thing, I’ve associated it with the future. If there’s one thing that distinguishes this century from the last is the ability to ‘print’ tri-dimensional models of things with just a few starting materials. Even more impressive, it is advancing extremely quickly too. There are already 3D printed buildings (https://www.cnet.com/au/news/worlds-first-3d-printed-apartment-building-constructed-in-china/), 3D printed organs (http://www.mirror.co.uk/science/amazingly-lifelike-human-body-functioning-8923717) even even the beginnings of 3D printed 3D printers (https://3dprintingindustry.com/news/reprap-snappy-is-the-most-3d-printable-3d-printer-yet-57957/). This is a technology that has developed so much in its first couple of years that we can only wonder what it will be able to do in 20 years or more.
