Researchers Make Progress with 3D-Printed ‘Cartilage-Mimicking Material’
“Printable hydrogel matches the strength and elasticity of human cartilage”
They don’t name which 3D-printer they used but they do specify it cost $300 – so something in the range of the M3D Micro or Printrbot, that is to say it is amazing what researchers are able to toy with for relatively cheap these days while advancing serious scientific studies!
A cartilage-mimicking material created by researchers at Duke University may one day allow surgeons to 3-D print replacement knee parts that are custom-shaped to each patient’s anatomy.
Human knees come with a pair of built-in shock absorbers called the menisci. These ear-shaped hunks of cartilage, nestled between the thigh and shin bones, cushion every step we take. But a lifetime of wear-and-tear — or a single wrong step during a game of soccer or tennis — can permanently damage these key supports, leading to pain and an increased risk of developing arthritis.
The hydrogel-based material the researchers developed is the first to match human cartilage in strength and elasticity while also remaining 3-D-printable and stable inside the body. To demonstrate how it might work, the researchers used a $300 3-D printer to create custom menisci for a plastic model of a knee.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
