The Smallest 3D-Printed Boat You’ve Ever Seen

You must be surprised When you see the iPhone 12 mini for the first time , which is literally tiny by contemporary standards.In the real world, , we may think of a small thing as nothing more than a bean or a grain of sand, or even a strand of hair.But you know what, scientists used a 3D printer to create a 3D Benchy boat, the length of which is 1/3 the thickness of a hair, 6 times larger than a bacterial cell.

Researchers used a scanning electron microscope to photograph the ship for purpose of showing its open cabin, a chimney, and even a small porthole. What’s most impressive is that the entire model is very tiny, which means it’s even smaller than a statuet created by artist Jonty Hurwitz in 2014 as a potential design for creating a little drug delivery vehicle.

The researchers conducted investigations into small particles called microswimmers that can move through fluids, and be followed by a microscope.They created many structures , including a spiky sphere, a spiral, a trimer,a 3D Benchy boat and so on. Research shows that particles created in a helix shape can go around and be efficient. 

“When it moves forward, often it needs to rotate, and that helps, for example, to speed it up.”Daniela Kraft said, a physicist at the Dutch university,adding that the small particle that goes to a particular part of the body to deliver drugs has to propel itself and may have to deal with the complex environment in human’s body.
