1.New 3D Printer can create complex Biological Tissues:
A UCLA bioengineer has developed a technique that uses a specially adapted 3D printer to build therapeutic biomaterials from multiple materials. The advance could be a step toward on-demand printing of complex artificial tissues for use in transplants and other surgeries.
2.Clinically-Validated 3D Printed Stethoscope:
The stethoscope, called the Glia model, was made using free open source software to keep costs low and allow others to easily access the code.
With the Glia template, the stethoscope can be made in less than three hours and costs less than $3 to produce.
Anyone with a 3D printer and access to ABS – a plastic used to make garden chairs and Lego – can create the device. The results of the study show it has the same acoustic quality as the best stethoscopes on the market.
3.3D-Printed Guide helps regrow complex Nerves after injury:
A team of researchers from various universities in U.S has developed a first-of-its-kind, 3D-printed guide that helps regrow both the sensory and motor functions of complex nerves after injury. The groundbreaking research has the potential to help more than 200,000 people annually who experience nerve injuries or disease.
4.Human Corneas 3D printed for first time:
Scientists at Newcastle University have 3D printed the world’s first human corneas. By creating a special bio-ink using stem cells mixed together with alginate and collagen, they were able to print the cornea using a simple low-cost 3D bio-printer. It’s hoped that this new technique could be used to help combat the world-wide shortage of corneas for the millions of people requiring a transplant.
5.Researchers 3D print prototype for ‘Bionic Eye’:
A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface.
This discovery marks a significant step toward creating a “bionic eye” that could someday help blind people see or sighted people see better.
6.3D-printed Lab Made Ears:
Scientists in China have used a breakthrough technology to grow new ears for five children born with an ear defect called microtia. Cartilage-forming cells were taken from the children’s ears and used to grow ear-shaped cartilage. The mold was filled in with cartilage cells taken from the children’s deformed ear that were further grown in the lab.
The scientiests used CT scanning and 3D printing to build a biodegradable scaffold that perfectly matches the 3D structure of the healthy ear of each of 5 children affected with Microtia.
Over 12 weeks, the cells started to grow into the shape of the mold. This Ear-mold was then grafted onto the children. The children started getting natural-looking ear over time.
