Scientists successfully print living cells for 3D printing by using "air microfluidics" technology Abstract: using a new technology called "air microfluidics", the Department of Twente university took the opportunity to go deep into the lithium battery industry, and scientists successfully used living cells to print three-dimensional structures. For example, this special technology can quickly produce micro components that are feasible and can be used to repair damaged tissues.

using a new technology called "microfluidics in the air", scientists at the University of Twente successfully printed three-dimensional structures with living cells. For example, this special technology can quickly produce micro components that are feasible and can be used to repair damaged tissues. This research work is introduced in detail in "scientific progress"
microfluidic technology is to deal with fluid droplets between micrometers and millimeters. In most cases, chips with tiny fluid channels, reactors, and other components are used: Lab on chip systems. Although these chips offer a wide range of possibilities, for example, in the production of lotion (droplets carrying another substance), the speed at which droplets leave the chip is usually in the range of microliters per minute. For clinical and industrial applications, this is not fast enough: filling a cubic centimeter of volume takes about 1000 minutes or 17 hours. The proposed technology can be completed in a few minutes
can we achieve higher speeds in the air instead of manipulating the fluid in the microchannel? This is one of the questions that researchers want to answer. In fact, it is possible to achieve this by using two "fluids". From one jet, another jet sends droplets. Creating jets is relatively simple. They move 100 to 1000 times faster than droplets on microchips. Speed is not the only advantage. By selecting jets containing different types of reactive liquids, "collision" will produce new materials. Generally speaking, the intelligent combination of fluids will produce printable solid components in a single step
3D printing of living cells
in this way, living cells can be captured in printable materials. The generated biological components are printed in a three-dimensional structure, which looks like a sponge and is filled with cells and liquids. These 3D modular biomaterials have internal structures very similar to natural tissues. Many 3D printing technologies by 2020 are based on the use of heat or ultraviolet light, both of which will damage living cells. Therefore, the new microfluidic method is the most promising technology in tissue engineering, in which the damaged tissue is repaired by using the patient's cell materials
this study was completed by Tom kamperman of the development bioengineering group led by Professor Marcel karperien and Claas Willem Visser of the fluid physics group led by Professor Detlev Lohse. Kamperman has just completed his doctorate. On this issue, Claas Willem Visser temporarily worked as a scientist at the Rubicon foundation of Harvard University. He will then return to Twente university to become an assistant professor. On the whole, both scientists are involved in the new iamfluidics derivatives, in which micro fluids in the air are used to make functional particles and materials
