Soon we will not even print at home, but grow

Scientists have developed an innovative technology for producing "living" building materials

Nobody can be surprised with houses printed on a 3D printer, we even have one in the Yaroslavl region. But the house that will "heal" the cracks is really something new. Of course, we are talking about the prospects, but given how time flies, they are not so distant. Perhaps our grandchildren will already be built from a new material that does not require firing or pressing. One of the American start-ups in Northern California led by industrial designer Ginger Dosier has developed a technology for growing sand bricks.

Plain sand is mixed with a special hydrogel containing the cyanobacteria Synechococcus, and the solution is placed in the desired shape. Within several days, the bacteria process the mixture, which, after hardening, is comparable in strength to concrete. The process is somewhat similar to the formation of corals, only programmed and controlled. Considering that bacteria, like any living organism, multiply, the material's prospects are impressive. Under certain conditions, it is realistic to grow volumetric structures of almost any size.

Even if we take the typical brick shape, the advantage over conventional ceramics is the absence of firing, that is, the absence of carbon dioxide emissions. On the contrary, bacteria absorb it during their vital activity. A very important property in our environmental realities.

Whether the development will be widely used in practice - time will tell. In the meantime, the Chinese, for example, "Mold" modern cottages literally from what is underfoot. In the video - just about the domestic printing house, built back in 2015.
