Print Green employes a mixtures of soil, water and grass seeds, supplanting the typical plastics we associate with 3D printing in order to print living, growing plants into any shape you might imagine.

Developed by a group of students at the University of Maribor in Slovenia, this 3D garden printer “uses a special CNC machine as a printing device. Instead of canvas it uses Styrodur, covered with black felt, bolstered with sponge.”

The machine layers up its creating, developing thick lines rich with seeds and nutrients that in turn grow into living prints. It can construct anything you want, from custom patterns to the shapes of faces as well as letters forming words or art to make green murals. And this is just the prototype: consider the possibilities of deploying mobile machines across landscapes, able to print out large-scale designs around buildings or in nature.
