YouTuber may create the world’s smallest working 3D printer

A YouTuber claims he has designed the smallest 3D printer in the world. The device, which is made of wood and plastic, measures only 18x31x41mm and weighs 17g, but is nevertheless functional.

The printer is about the same height as the length of a matchstick, says YouTube user My N Mi see in a video. Furthermore, according to the user, the device has an accuracy of 0.135mm, a layer thickness of between 0.005 and 0.3mm and a construction volume of 11x11x17mm. In the video, My N Mi shows that the 3D printer is able to print a green, transparent robot, including small details on its head, torso and legs.

To do this, the YouTuber injects a few drops of liquid resin into the tank of the printer. A motor moves the build plate up and down while a UV laser draws the shape of the object to be printed in the tank. The lettuce printing technique is used, but on a very small scale. The printer receives its print data via a micro USB cable at the back.

Unfortunately, the user does not mention which components were used for the printer. How exactly My N Mi managed to put together such a small salad printer remains a mystery for the time being.
