YouTuber May Create World’s Smallest, Working 3D Printer – Computer – .Geeks

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

The printer is about the height of a matchstick and less wide than an SD card, 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 building 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 sprays a few drops of liquid resin into the tank of the printer. A motor moves the building plate up and down while a UV laser draws the shape of the object to be printed in that tank. The lettuce printing technique is therefore 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 are used for the printer. How exactly My N Mi managed to assemble such a small salad printer is still a mystery for the time being.
