Who says 3D printers can only print three-dimensional things, but they are still proficient in plane printing. Recently, Gizmodo announced the news about the watercolorbot 2.0 painting robot. Painting has no borders, so it's easy to draw all kinds of famous paintings.
You only need to link the watercolorbot 2.0 to the computer to change the beautiful pictures on the screen into paper, which is different from the ordinary printer. It is painted on paper with a brush, which is the rhythm of liberating the hands of migrant workers.
