Printers are quickly becoming standard apparatus in biomedical engineering labs across the globe. To keep up with this trend, researchers at the Hangzhou University of Electronic Science and Technology have created China’s first domestically produced bioprinter.

The Hangzhou team, led by Xu Ming-En, built their bioprinter to operate using consecutive layers of hydrogel that can be embedded with cells. As this process happens over and over, a biomaterial is built. According to the Hangzhou team, their new printer is highly accurate, creates materials with a low cell damage rate, and has two nozzles for injecting materials at both high and low temperatures.

In recent tests, Xu has created objects like a thumb sized ear in roughly fifty minutes, not counting the time spent “curing” the print in a cross-linking agent. While printing grotesques like miniature ears is proof that the process works, Xu says that his printer is also capable of printing more complex tissues, such as liver lobules. In fact, Xu explains, “The process takes around forty minutes to an hour".

For the time being, Xu’s bioprinter will be used to build muscle fiber and blood vessels, while also perfecting their method for building cartilage-based features, like ears and noses. As his printer becomes more sophisticated, Xu hopes to create more complex organs, like livers and kidneys.

If either Xu or any of his contemporaries could develop a sufficiently sophisticated bio printer, the future of organ transplants could be revolutionized. Organs, which today must be carefully matched between donor and recipient, could be built specifically for an individual.

Biomaterial 3D printer "Regenovo" invented in China

The printer has become the first 3D tissue printer with Independent Intellectual Property Rights (IIPR) in China. (Xinhua/Xu Yu)

Hospital uses 3D printed orthopedic implants

Updated: 2013-08-06 19:19

Using a printer to produce lifesaving medical implants and body parts might sound like science fiction, but it is already a reality in China.

Peking University Third Hospital, a top hospital in China, recently announced that its Orthopedics Department has been using enhanced implants produced by a 3-D printer in a clinical trial, with promising results.

"We started clinical trials on 3-D produced implants late last year, and now we have used dozens of such implants in more than 50 patients," said Liu Zhongjun, director with the department.

"All the patients recover very well. Nobody seems to have any undesirable side effects or adverse reaction."

The process of 3-D printing, or additive printing, applies successive layers of material in different shapes to make a three-dimensional solid object from a digital model.

For the implants, the material used is titanium, a special metal that has been used for orthopedic implants for decades.

However, the shapes of the 3-D products are much different than earlier models.

Orthopedic implants are artificial devices incorporated into joints and bones to restore normal functions, such as spine implants to help anchor the spine, or hip replacements.

They are widely used for patients suffering from bone damage caused by injury or disease, such as osteoarthritis, which causes pain and stiffness in joints.

Chinese Scientists Are 3D Printing Ears and Livers – With Living Tissue

By J. T. Quigley

August 15, 2013

Researchers in China have been able to successfully print human organs using specialized 3D printers that use living cells instead of plastic.

Researchers at Hangzhou Dianzi University actually went as far as inventing their own 3D printer for the complex task, dubbed the “Regenovo.”

“Xu Mingen, Regenovo's developer, said that it takes the printer under an hour to produce either a mini liver sample or a four to five inch ear cartilage sample. Xu also predicted that fully functional printed organs may be possible within the next ten to twenty years,” stated 3D Printer World.

TODAY'S MOST CREATIVE PEOPLE: THE SCIENTISTS BEHIND THE WORLD'S FIRST WORKING, 3-D-PRINTED KIDNEY

RESEARCHERS AT CHINA'S HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGY HAVE CREATED THE WORLD'S FIRST WORKING, 3-D-PRINTED KIDNEYS.

In the future, doctors may be able to 3-D print functional human organs at a moment's notice for those in need of transplants. For now, that's not quite possible--but we may not be far off. The video above shows researchers from China's Huazhong University of Science and Technology, led by head researcher Xu Mingen. They are the world's first to 3-D print transplantable, living human kidneys.:coffee:

The printed kidneys are only a fraction of the size of normal human kidneys, which are about the size of a fist, but about 90% of their cells are alive. The miniature organs are capable of removing waste and secreting fluids just the way normal kidneys can.

The idea of 3-D printed organs has been around for some time--it made waves at the 2011 TED conference, when surgeon Anthony Atala discussed the idea of printing a kidney and introduced a young patient who had received an artificial bladder engineered using similar technology. We've also seen functional human liver tissue developed by the firm Organovo.
 
You know what comes to my mind in the first place when I see the title?

Revolution of plastic surgery ............:woot:

But Chinese are not fond of plastic surgery,at least not to the degree that South Koreans and Japanese are。;)
