Researchers at the University of Buffalo have unveiled their new 3D printing method with an incredible video showcasing what may soon be the future of rapid, artificial organ fabrication.
The research team’s incredible seven-second, 19-minute time-lapse video showcasing the impression of a hand, which would take six hours to create using conventional 3D printing methods.
“The technology we have developed is 10 to 50 times faster than the industry standard, and it works with large sample sizes that were very difficult to achieve before,” says study co-lead author Ruogang Zhao, Ph.D., associate professor of biomedical engineering.
The technique is called stereolithography and uses hydrogels, a gelatinous substance that is used to make diapers, contact lenses, and most importantly, tissue engineering scaffolds.

The team at the University of Buffalo made centimeter-sized hydrogel models which, in turn, reduced the deformation of structures sometimes encountered in other 3D printing methodologies.
According to co-lead author Chi Zhou, the team’s method would be ideal for imprinting cells with integrated blood vessel networks, a daunting prospect even now, but perhaps more mainstream medical technology in the near future.
These advances in 3D printing are critical to the development of fully functional 3D printed organs in a growing crossroads between the manufacturing and biomedical device industries, which could save countless lives around the world in the future. . In 2018 alone there were 146,840 organ transplants somewhere in the world.
