Best 3D printing technologies used in medicine
The 3D printing, which is taking its first steps in recent years, has the potential to be one of those things that can change our way of thinking about the world around us. Medicine advances so quickly these days, despite the reduction in funds for research, it molds to the future is always a small chance that as in the case of best 3D printing technologies are increasingly being used in healthcare settings .
The main problem facing medicine in the field of organ donation is to patient refusal . The lack of available organs is a cause of constant battles over the rationing of resources in hospitals.
A new technique developed by researchers at He riot-Watt University in Scotland in collaboration with various companies related to new technologies have opened a new door of hope eliminating the need to donate organs to save the lives of patients who need them.
The new process takes advantage of opportunities to grow the stem cells in laboratories. Thanks to a printer could create a three-dimensional sphere cultures containing embryonic cells floating in a nutrient-packed liquid medium. These cells accumulate new layers forming between them finally become any organ of the body.
A group of scientists from the University of Oxford have used a 3D printer to create a synthetic fabric that could have a variety of medical applications, including the ability to transmit electrical signals long distance as the nervous tissue of our bodies.
The printer, created specifically for this experiment, liquid droplets placed in an oil solution. Drops, rather than stick together, they separate naturally. When the drops are printed network 3D creating tens of thousands final result is achieved with an elasticity similar to that of the brain tissue . Unfortunately by the time these networks, researchers have a stable life for a couple of weeks.
Researchers at Cornell University in the U.S. have been able to replicate through 3D Printing a human ear. The artificial ears is traditionally generated from materials which had the consistency of Styrofoam . Children born with congenital diseases such as microdot were subjected to complicated operations in which the end result was almost never expected.
To make the new implants with these ears a 3D image digitized them to build a mold is needed. Within the scientists injected collagen mold with 250 million cells of the cartilage of the ears of cows. The resulting gel has a high density of jelly-like consistency and thanks to collagen, cartilage itself that develops with time the human body can grow on the artificial surface as if it were a scaffold.
