A technology company based in Boston has finished what it says is the largest 3D printed building on the planet within 2 days.
3D printing machine manufacturer Apis Cor recently constructed a two-story executive office. This is for a Dubai government agency using one mobile printer.
The building stands at 31 ft tall with an area of 6,889 sq.ft. The walls of the building were printed. But the roof, insulation, windows, and foundation were installed by the use of conventional building techniques. This is according to Apis Cor CEO Nikita Cheniuntai.
The printing of the walls was done on-site by transferring the printer just about the construction site using a crane.
The firm’s proprietary printing combination includes off-the-shelf supplies such as cement, sand, gypsum, and other proprietary elements that are accessible for industrial use. The whole procedure happened in an uncovered area in desert conditions. Therefore, finding the perfect blend for the printed materials was a key goal of the task.
“The Dubai climate is very harsh, where temperature and humidity change significantly even within a day, so the material has to behave the same way all the time despite the changing of the environmental conditions,” said Cheniuntai.
Cheniuntai said that building printing is achievable in every type of climate. This is provided that the project members can make the appropriate mix of materials and the blending machine may work accurately.
Apis Cor has been 3D printing houses majorly and plans to provide its technology in the US next year. This is after it clears constructing code laws. In 2017, the firm printed a 400 sq. ft. demonstration home in 24 hours for around $10,000.
“Gaining industry approval for the use of 3D printing technology to build homes has been one of the major barriers to mass availability,” he said, adding that his team’s strategy is comparable to reinforced concrete masonry unit (CMU) walls, which are approved in the U.S.
“We can ensure our 3D-printed walls meet existing building standards by mimicking the characteristics of the CMU wall,” he stated.
Dubai leads globally in 3D construction printing. The Dubai 3D Printing Strategy is pushing the nation toward more 3D printed structures. It has the order that by 2025 each new structure will be 25 percent 3D printed.
The website of the country states different reasons for the action. They include reduced labor costs, waste, and reduced construction costs.
