New 3D Bioprinting Technique: In-Air Microfludics

The American Association for the Advancement of Sciences, also known as AAAS, recently released in a paper that their in-air microfluidics technique can enable the rapid production of micro building blocks.

Microfluidic Chips, which hold small fluidic channels and used to manipulate drops of fluid, is said to help repair damaged tissue, however the chips alone cannot mass produce enough for clinical use.

However, the AAAS have created a 3D bioprinting technique which could facilitate this idea and can offer a solution whereby the fluids are passed through the air as opposed to microchannels found in Microfluidic chips, hence producing a quicker technique. Using two jets of droplets, this technique shoots the microfluid up to 1000 times than the standard microchip technique.

As a result, using the jets with a variety of fluids can be used creating new materials as they collide. Through this process, living cells can be captured inside printable material which is then printed in a 3D structure resonating a sponge, filled with cells and fluid which has an internal structure similar to natural tissue.

Due to most 3D printing techniques damaging living cells as they are created through heat or UV light, this new technique from AAAS is looking to be a stable opportunity for tissue repair in tissue engineering.
