Rapid 3D printing methods are evolving to 3D printed organs | Instant News



It looks like science fiction: a machine is immersed in a light yellow squishy shallow bucket, and then it pulls out a life-sized hand.

But the 7-second video played at an accelerated rate from 19 minutes onwards is real.

It takes six hours to make this hand using traditional 3D printing methods, which shows what the University of Buffalo engineers say is the progress made in 3D printed human tissues and organs-this biotechnology can eventually be saved due to shortages And countless life donor organs were lost.

Dr. Zhao Ruogang, the co-lead author of the study, said: “The technology we developed is 10 to 50 times faster than industry standards and can handle large sample sizes that were previously difficult to achieve.” Associate Professor of Biomedical Engineering.

This work is described in a study published in the journal on February 15 Advanced healthcare materials.

It centers on a 3D printing method called stereolithography and jelly-like materials called hydrogels, which can be used to make diapers, Contact lens Scaffolds in tissue engineering.

The latter application is particularly useful in 3-D printing, which is why the research team spends most of their energy optimizing to achieve its incredibly fast and accurate 3-D printing technology.

“Our method can quickly print a centimeter-sized hydrogel model. It greatly reduces part deformation and cell damage caused by deformation. Prolonged exposure Respond to the environmental pressures you usually encounter in traditional 3D printing methods,” said Dr. Chi Zhou, associate professor of industrial and systems engineering, another major collaborator of the study.

The researchers said that this method is particularly suitable for printing cells with embedded blood vessel networks, which is an emerging technology that is expected to become a core part of 3D printing products. Human tissue And organs.
