Researchers at the University of Maine have managed to 3D print an organic building material with the strength of steel.

The SM2ART Nfloor is printed as a single piece in about 30 hours, which is a third faster than building something comparable by hand according to TechXplore.

The nice thing about this set-up is that these panels can be printed in bulk off-site and get shipped to the construction area. Since there are already channels in the floor for electrical and plumbing, the only other thing that needs to be applied by hand is soundproofing and floor covering.
