This 3D Printer Uses A Mosquito 😮

When they removed the feeding tube from the mosquito, it was hollow and straight, but it was too fragile to use directly.So they coated it with resin to make it stronger, and attached it to a needle tip.

Then they built a 3D printer around it, and as ink flowed through the tube, it printed lines finer than a grain of sand, letting them build tiny structures most printers could never make, all thanks to a mosquito.
