Artificial blood vessels created on a 3D printer

Artificial blood vessels made on 3D printers may soon be used for laboratory transplantscreated organs.
So far, the stumbling block of tissue engineering has been to provide artificial tissues with nutrients that must be reached through a capillary tube.
A team at the fraunhove Institute in Germany solved the problem using 3D printing and a technology called multi-photon aggregation.
The results of the survey will be presented at the Biotechnica exhibition in Germany on October.
Among the thousands of patients in urgent need of organ transplants, it is inevitable that some people do not receive organ transplants in time.
In Germany, for example, more than 11,000 people were on the waiting list for organ transplants in 2011 alone.
Make sure more patients receive these lives.
Rescue surgery, researchers at global tissue engineering have been working to make artificial tissues and even whole organs in the laboratory. But for a lab-
It needs to be equipped with artificial blood vessels to make the organs work.
The tiny, extremely complex tubes that our organs naturally possess for carrying nutrients.
Many attempts have been made to make a synthetic capillary, and the latest attempt by the German team seems particularly promising.
\"Individual technologies have come into play and are currently working in the testing phase;
The prototype of the combined system is under construction, \"said Dr. Gunter Tovar, who is the head of the bio-ap project at the IGB Institute for Interface Engineering and Biotechnology at Stuttgart fraunhove.
3D printing technology has been applied more and more in many industries, from making clothing, building models to chocolate food.
But this time, Dr. Toval\'s team completed a more challenging printing task.
In order to print things as small and complex as blood vessels, scientists have combined 3D printing technology
Photon aggregation-
Shine a strong laser on the material and stimulate the molecule at a very small focus.
The material then becomes an elastic solid, enabling researchers to create highly precise and resilient structures that can interact with the natural tissues of the human body.
As a result, synthetic tubes are not repelled by organisms, and their walls are covered by modified biological molecules.
This biological molecule is also present in the composition of \"ink\" and synthetic polymers used for vascular printers.
\"We are laying the foundation for applying rapid prototypes to elastic and organic biological materials,\" said Dr. Tovar . \".
\"The vascular system is very dramatic about what opportunities this technology offers, but it is definitely not the only possibility.
