3D printers are smaller than cells

South Korean researchers are developing 3D printing technology that allows them to print smaller, cellular details.

3D printers are small objects such as "bacteria"

3D printing is no longer a strange thing in today's life. However, the drawback of this technology is that it still does not print very small objects. And this is the goal that a team of scientists from the Ulsan Institute of Technology and Science (South Korea) is aiming for

They are developing a 3D printer that can print small details of just 0.001 millimeters. Let's imagine a blood cell ranging from 0.006 to 0.008 millimeters to find out how small the device is.

This printer works similarly to the average inkjet printers we use every day, but the "electrohydrodynamic" printer (the provisional name of the printer under study) uses a special ink to Produces details of the product from the curves of bridges, zig-zag lines, or even cylindrical objects.

Today's 3D printers have an inherent restriction that makes it very difficult to produce smooth details . Meanwhile, in high detail, 3D printers of Korean scientists completely overcome this problem. These printers, when fully manufactured, can help a lot in the production of computer chips, boards or items that require a lot of small details.

"This technology will provide a new model in the field of 3D printing," said Jang-ung Park, a professor of materials science and lead author of the study. He believes that this research will bring a breakthrough in the application of 3D printing technology , especially in the manufacture of wearables.
