The 32-by-32 foot printer works in much the same way as its much smaller plastic-printing additive cousins — except that it uses a specially mixed concrete to build layer by layer.
Faster, Cheaper, Stronger
Such a process has key advantages over conventional builds: It’s significantly faster, it’s far more judicious with material usage, and could even cut construction costs as a result.
“The material’s compressive strength is three times greater than that of the conventional quick build brick,” Marijke Aerts, the project manager, told New Atlas. “Besides the fibers in the concrete, the amount of wire-mesh reinforcement used is extremely limited. As a result of the printing technology used, formwork was redundant, saving an estimated sixty percent on material, time, and budget.”
The 980 square feet two-story home is still more of a demo than a livable structure, but it’s technically large enough and even features sustainable amenities, like solar panels and underfloor heating.
