German researchers say that they are developing new techniques for printing blood vessels using stereoscopic printers. It is believed that in the near future, the printed blood vessels can be installed on artificial organs and bring good news to patients who need organ transplants.
Organs do not repel
According to researchers at the Wolff Institute for Interface Engineering and Bioengineering in Germany, blood vessels are small and the network structure is complex and printable. Therefore, they combine three-dimensional printing technology with two-photon polymerization technology.
When printing, the printer emits two powerful lasers that focus on the same molecule. This molecule simultaneously absorbs two photons, the so-called two-photon polymerization. The two-photon-polymerized molecule becomes a flexible solid. With this printing process, researchers can use it to create high-precision elastic structures that are blood vessels. The blood vessels printed through this process can “communicate†with human tissue and will not be rejected by organs.
Researchers say that the "ink" used for printing is biomolecules and artificial polymers. The research project leader Gunter Tovar said that researchers have successfully printed a single blood vessel publication and that complex vascular network models are being "built."
Wide range of applications
The researchers plan to present this research result at the Biology Show held in Germany in October 2011.
Every year, a large number of patients around the world wait for organ transplants. Many people cannot wait for suitable organ donation in their lifetime. To solve this problem, multinational researchers are working hard to study artificial organs. However, besides how to "manufacture" organs, what bother them is another problem: how to provide nutrition to artificial tissues or organs through blood vessels.
BBC believes that food packaging, Germany, the future of this three-dimensional vascular printing technology is full of hope.
Food can also print
Today, three-dimensional printing technology has been applied in many fields. Cornell University researchers have developed a food printer. Using special “inks†such as cheese, chocolate, and cake paste, food printers can “print†cookies, apple pies, and other foods.
British researchers have also developed a three-dimensional printer capable of printing plastic or metal objects. They are installed in stores in Corley, and customers can print their own designs of jewelry and even clothes and shoes.
