This Ink Is Alive and Made Entirely of Microbes
The New York Times
Scientists have created a bacterial ink that reproduces itself and can be 3D-printed into living architecture.
The thought of combining a printer (the bane of office workers) with the bacterium E. coli (the scourge of romaine lettuce) may seem an odd, if not unpleasant, collaboration.
But scientists have recently melded the virtues of the infuriating tool and of the toxic microbe to produce an ink that is alive, made entirely from microbes. The microbial ink flows like toothpaste under pressure and can be 3D-printed into various tiny shapes — a circle, a square and a cone — all of which hold their form and glisten like Jell-O.
The researchers describe their recipe for their programmable, microbial ink in a study published on Tuesday in the journal Nature Communications. The material is still being developed, but the authors suggest that the ink could be a crucial renewable building material, able to grow and heal itself and ideal for constructing sustainable homes on Earth and in space.
