Rapid 3D printing may be the secret to 3D printing organ development

 


You may not have a flying car yet, but are there any 3D printed organs? The sci-fi fantasy is one step closer to reality thanks to the rapid 3D printing method developed by engineers at the University of Buffalo.

Their study was recently included in a study published in the journal Advanced Healthcare Materials. Here, And, frankly, the above gif is also shown. This speeded-up video shows a 3D printer that fully builds an artificial hand in just 19 minutes. This is a 6-hour task using traditional 3D printing methods.

“The technology we have developed is 10 to 50 times faster than industry standards and works with large sample sizes that were previously very difficult to achieve,” said Biology, co-lead author of this study. Ruogang Zhao, an associate professor of medicine, said. Engineering at university, Press release Friday.

This process relies on stereolithography, a long-standing 3D printing method that uses a laser to cure a liquid resin, and a jelly-like substance called hydrogel that can absorb large amounts of water without dissolving. Hydrogel is a contact lens, adhesive, Scientists have also potentially experimented with them, but disposable diapers Biomedicine treatment..

According to researchers, this method is particularly suitable for correctly printing all the small details inside cells in which the vascular network is embedded. It is expected to play an important role in the final production of 3D printed human tissues and organs.

“Our method allows us to quickly print centimeter-sized hydrogel models, which results in component deformation and cells caused by prolonged exposure to the environmental stresses commonly found in traditional 3D printing methods. Damage is significantly reduced, “said Chi Zhou, another co-lead author of the study, an associate professor of industrial and systems engineering at the university. ..

The team’s research was funded by the National Institute of Biomedical Imaging and Bioengineering, the National Institute of Health, the UB School of Applied Sciences and Jacobs School of Medicine and Biomedical Sciences, according to a press release.

The idea of ​​a 3D printed organ still seems to me a futuristic giant jumbo, but I guess if you can already eat it 3D printed meat so 3D printed house Where you keep you 3D printed gun, And the sky is the limit.
