The iBox Nano Printer is probably the smallest one. Its creators claim that the iBox Nano printer is not only the shortest resin printer, but also the most affordable and lightest new 3D printer. It implements these points in several ways, namely by using LED instead of DLP bulb light, which reduces the size and noise of the printer, and part of the actual printer body is acrylic. The end result is such a 3-pound small printer. The inventors also stated that, statistically, users who buy larger and more expensive 3D printers tend to print only small objects.
You don't need to install any printing software, everything is handled via WiFi and a web browser, and you can even print from Android and iOS devices. If you want to know what the nanometer printer actually does, it can print high resolution pieces, rings, or even a tooth. It requires a $269 donation because the project has a target of $300,000 in funds, and as of the time of this press release, it has reached approximately $92,000.
