The world’s tiniest 3D printer is smaller than a match

We will give you some hints, though. The printer is so small that the material it needs to print its structures has to be added with a needle. Yes, you read that right: a needle. That’s how small this 3D printer is.

It takes some time to produce the final form, but the printer finally showcases a tiny figurine of a man. At first, it seems like the printer is not doing much of anything (just going up and down with no end result). But surely enough, after several minutes, the printing head pulls up, and the figurine is introduced. You have to see it to believe it.
