Physicists 3D Print a Boat Small Enough to Fit Inside a Human Hair

Because our scientists were so preoccupied with whether they could that they didn’t stop to think if they should, physicists at Leiden University have 3D printed a tiny tugboat only 30-microns in length. For reference, an average human hair is about 90-microns in width, although mine is much thicker because I shampoo with a product specifically formulated for bears.

The microscopic printing of 3DBenchy the tugboat (a commonly printed 3D test object due to its challenging features, namely its open cockpit) was created as scientists explore the development of uniquely shaped synthetic microswimmers, and can be propelled via onboard platinum reacting with hydrogen peroxide.

So basically in the future, there are going to be a bunch of tiny tugboats cruising around in your bloodstream, monitoring your vitals and administering medicine, and helping you live longer. Of course, you know what else would help you live longer? An apple a day. And, based on my entire apple pie and half-gallon of ice cream a day habit, I should practically be immortal.
