Russian company AMT-SPECAVIA recently introduced a new line of construction 3D printers in Yekaterinburg for the INNOPROM international trade show. Among the new machines is the AMT S-500, marketed as being the largest construction printer in the world, and the AMT S-300.
When it comes to construction 3D printing, it is usually wise to exercise some healthy skepticism, especially with claims such as AMT-SPECAVIA’s. According to the company, the large-scale AMT S-500 has a build capacity of 11.5 x 11 x 15 m—about the height of a five or six storey building—and can even be extended to 31 x 11 x 80 m to make multi-storey high rise buildings.
Though we’re as eager as the next person to see the first 3D printed high-rise, we are also curious about the types of structures that the AMT printer is capable of building. (Even if the build capacity claim is possible, there is no word on the quality of the structures built yet.)
The other printer presented by AMT-SPECAVIA, the more modest AMT S-300, reportedly has a working field of 11.5 x 11 x 5.4 m. This machine, says the Russian company, is ideal for building one to two storey buildings with a floor span of up to 120 square meters. It adds that structures can be printed in situ, directly onto a foundation.
Other features of the AMT construction 3D printers include print speeds of up to 2.5 cubic meters in an hour. (For comparison, 3D Printhuset’s BOD2 construction 3D printer, which was recently granted the first EU tender for a construction 3D printing technology, has a rapid print speed of 18 meters/minute.)
3D printing the first residential house in Europe
In a high-profile event, AMT-SPECAVIA last year 3D printed the “first residential house in Europe and CIS.” The structure, which now stands in Yaroslavl, Russia, was started in 2015, when AMT-SPECAVIA began printing segments of the house’s frame. Fast forward to 2017, and the 3D printed house was assembled, connected to utility systems and ready to welcome its first residents.
“It was important for us to set a precedent,” said Alexander Maslov, general director of AMT-SPECAVIA at the time. “To show in practice that 3D construction technology is working…Printing was done in the shop with the smallest printer. We printed the building in parts (the walls of the house, decorative elements, the tower), took the parts to the construction site and assembled them as a Lego kit. Since then, of course, the equipment has been improved: both the speed of printing and the quality. But even our first model proved to be reliable and efficient equipment.”
Building on the success of its first 3D printed house, AMT-SPECAVIA seems dedicated to working with larger machines and building on site, rather than pursuing the assembly route. According to the company, its first S-500 printer is already being prepped to ship out this year.
