World’s Smallest 3D Printer is 41mm Tall, Outputs Detailed Models

Most 3D printers are relatively large. Even the Ender 2 Pro, the perfect 3D printer for those with limited space, measures 421 x 383 x 465 mm (16.6 x 15 x 18.3 inches) and weighs 4.5 kg (10 lbs). But one manufacturer is pushing the boundaries of what’s possible, producing sharp prints yet measuring just 18 x 31 x 41 mm (0.7 x 1.2 x 1.6 inches) and weighing just 17 g (0.03 lb). We are showing off a practical 3D printer that weighs only . This is the smallest unit we have ever seen or heard of, and very likely fulfills the inventor’s claim of being the world’s smallest 3D printer.

In a video on his YouTube channel, a user with the username My N Mi shows a small SLA 3D printer outputting a tiny translucent green robot model in just a few minutes. The tiny printer appears to be made out of a combination of wood and plastic, with a motor moving the build plate up and down and invisible LEDs imprinting light into the resin material in a tiny tank.

This is how all SLA (aka resin) 3D printers work, but on a smaller scale. At one point, you see My N Mi filling a tank with tiny drops of resin from a syringe. The printer is powered and receives data via the rear micro USB port.

In the video, My N Mi claims that their printer has a maximum build volume of 11 x 11 x 17 mm, an accuracy of 0.135 mm and a layer resolution of 0.005-0.3 mm. By comparison, the best resin 3D printer we tested, he Anycubic Photon M3 has a build volume of 163 x 102 x 180 mm and a Z-axis accuracy of 0.01 mm. However, the M3 weighs 7 kg (15.4 lbs).
