3D-printed Blood Vessels

Wissenschaftler am Fraunhofer Institut haben 3D-Printing und 2-Photonen-Polymerisation kombiniert, und damit künstliche Venen und Arterien gedruckt. Die sind nötig, um künstliche, gezüchtete Organe aus dem Labor an Patienten „anzuschließen“. Und sie kommen wohl demnächst aus einem 3D-Drucker. Welcome to the Future.

Until now, the stumbling block in tissue engineering has been supplying artificial tissue with nutrients that have to arrive via capillary vessels. A team at the Fraunhofer Institute in Germany has solved that problem using 3D printing and a technique called multiphoton polymerisation. […]

To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation - shining intense laser beams onto the material to stimulate the molecules in a very small focus point. The material then becomes an elastic solid, allowing the researchers to create highly precise and elastic structures that would be able to interact with a human body's natural tissue.
