High technologies gradually penetrateconstruction industry, creating conditions for a successful solution of the housing issue. California-based company Mighty Buildings announced the start of production of full-fledged houses using artificial stone and 3D printing technology. The firm is currently able to manufacture 33 square meters (350 square feet) homes and is already implementing the first real projects in California. The time to create a completely finished home is only 24 hours.
Several companies have previously announcedreadiness to use 3D printers in the construction of houses. For example, S-Squared is already working on the "stamp" of social housing in Mexico. However, the construction technology of Mighty Buildings has two main advantages: the use of a unique building material of artificial stone and the modular nature of the houses, which allows them to be built at the company's production facilities with further delivery to the customer in California.
Traditionally in 3D printers during constructionhouses use a concrete mix, which requires technological equipment to form walls and ceilings after printing. However, Mighty Buildings uses a synthetic stone that hardens almost instantly when exposed to ultraviolet rays. Under these conditions, during the construction of horizontal planes (ceiling or floor), no supporting structure is required. Immediately after printing at home, all surfaces are processed, polished by a robotic complex, preparing walls and ceilings for finishing.
The next advantage of Mighty technologyBuildings is a modular, universal character of houses, which allows building a 33-meter "box" at the company's plant, with further delivery to the place specified by the customer. This method significantly reduces the time for making a house, improves the quality of structures, the purity of their processing and, most importantly, reduces the cost of the facility being built. In the future, Mighty Buildings plans to robotise up to 80% of construction work.
