Hip disorders such as cartilage degeneration or bone fractures are common pathologies which are often treated with prosthetic surgery. Andrea Calvo-Echenique from the University of Zaragoza, Spain investigated how to prolong the lifespan of hip prostheses, and assessed the best options by comparing different stems and bearing materials. Her goals were to reduce the wear in bearing surfaces, as well as reducing the loosening of the stem, which tends to be caused by a lack of mechanical load in the bone. She received a Mimics innovation Award for the best poster submission in 2015.
Stent-assisted coil embolization (SACE) is widely accepted for the endovascular treatment of wide-neck or complex cerebral aneurysms. Dr. Kenichi Kono and his team at the Showa University Fujigaoka Hospital of Kanagawa in Japan have assessed and compared the hemodynamic effect of stent struts and straightening of vessels. They tested out the effects of stent placement on reducing flow velocity in sidewall cerebral aneurysms with the goal of reducing recanalization rates. Thanks to this groundbreaking study, Dr. Kono was the Global Mimics Innovation Award winner in 2015.
What do donor hearts and 3D Printing have in common? The answer to this is the University of Minnesota’s Visible Heart® Lab. Not content with simply teaching their students with 2D images, the team at the lab has moved their academic approach to a whole new level: 3D models of real human hearts. Imagine being able to train as a surgeon with a complete, tangible heart model, as opposed to learning off paper! And imagine acquiring the skills to make 3D models for any operation you might perform throughout your career? Here’s how Materialise enables the Visible Heart Lab’s unique approach to teaching, education and research.
Designing structures and devices that protect the human body from shocks and vibrations during high-velocity impacts is a universal challenge. Scientists and engineers focusing on this challenge try to understand and replicate or improve on anti-shock mechanisms found in nature. The woodpecker stands out in this field of study: it can peck trees at high frequency (up to 25 Hz) and high speed (up to 7 m/s and 1200 g deceleration) without suffering any brain injury. So how can woodpecker anatomy help improve anti-shock devices?
There are many hypotheses about the effects of human characteristics on injuries, and they can be assessed more accurately through the use of a parametric human finite element (FE) model. This model can be morphed automatically into other models to represent a diverse population. Dr. Jingwen Hu and his team at the University of Michigan Transportation Research Institute, USA have managed to develop this very same parametric model, and have given it the ability to predict injuries and represent different human anatomies. Dr. Hu won the first prize for the “Best Article Award: North & South America” of the Mimics Innovation Awards in 2015.
Abdominal Aortic Aneurysms (AAA) occur in 5 to 9% of the population over the age of 65 years and transmural aneurysm rupture is the 10th most common cause of death in the industrialized world. Dr. Bram Trachet, post-doctoral researcher at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, explores novel high-resolution imaging techniques as well as image-guided histology to visualize experimental aneurysms in laboratory animals. In 2015, he won a Mimics Innovation Award for his research on the morphology of abdominal aortic aneurysms in mice infused with angiotensin II. The essence of his paper will be presented in this blog post.
As the winner of the first prize for the “Best Article Award: North & South America” of the Mimics Innovation Awards in 2015, Dr. Jingwen Hu’s paper has the potential to contribute significantly to automobile safety.
A research team led by Tuomas Tallinen (Department of Physics and Nanoscience Center, University of Jyvaskyla), Jun Young Chung and Lakshminarayanan Mahadevan (Paulson School of Engineering and Applied Sciences, Harvard University) is studying the folded structure of the human brain. Their findings published in Nature Physics indicate that the convoluted structure can be attributed to mechanical compression. A 3D-printed model was used by the researchers to support their theory.
After years of lobbying, the DNA Learning Center in Cold Spring Harbor, New York, finally gained permission to recreate the world’s only 3D copy of Ötzi, the mummified ‘Iceman’ discovered in the Tyrolean Alps by a pair of hikers in 1991. Renowned paleo artist Gary Staab reached out to Materialise to make the project a reality, and worked closely with Eric Renteria, our very own application engineer. Here is a detailed report of how he recreated a life-sized model of the world-famous Iceman.
Five thousand years after he was murdered on a Tyrolean Alpine peak, Ötzi rose from liquid resin on a Mammoth stereolithography 3D printer at Materialise — or rather, his 3D-printed twin did. An interdisciplinary team, comprising scientists, archeologists and historians, turned to Materialise to create the first 3D-printed replica of Ötzi’s mummified body in aid of research. Watch the whole process of 3D printing a mummy here!
