Taking “moss graffiti” to it’s logically industrial application, several art education students at the University of Maribor in Slovenia challenged themselves to design a 3D printer and concluded with this machine whose results are pretty intriguing.
Designed around a modified CNC machine, the printer dispenses a mixture of soil, seeds, and water. The mixture holds its form quite well, and over time grass will grow from the print. You can see in the video below the unit dispenses around a cup’s worth of mixture to print the words “print green,” the name of the project in English (translated from “tiskaj zeleno” in Slovenian).
The device is also capable of printing along the z-axis, for creating bowls and other shapes from mud, while incorporating a top-layer of the grass seed mixture for results like this:
