Researchers Devise Rapid 3D Printing Method for Human Organs

"The Holy Grail of 3D bioprinting is to one day be able to fabricate full-sized human organs and tissues to replace the real thing in cases of transplant surgeries and other biomedical applications.
Researchers at the University at Buffalo have made a significant step not only to achieve this endeavor but to do it quickly. A team of researchers there has developed 3D-printing technology that has demonstrated rapid printing of life-sized organs and limbs such as a human hand in less than 20 minutes.
The team—co-led by Ruogang Zhao, associate professor of biomedical engineering, and Chi Zhou, associate professor of industrial and systems engineering—created a 3D-printing method based on stereolithography that uses hydrogels to produce organs quickly. Hydrogels are materials comprised mainly of water that are already used to produce contact lenses and diapers as well as in other applications...." Lire la suite
