At the international industrial exhibition Innoprom-2018 in Yekaterinburg, the Russian company AMT-Spetsavia presented two new models of construction 3D printers. The key difference between the S-300 and S-500 models is that the height of the solution supply in the second is 10 m higher and reaches 15 m. This is the size of a 5-storey building, which makes this printer the largest in the world today.
The working platform of the S-300 model is 11.5 × 11.0 × 5.4 m, it is intended for printing one- and two-story buildings. With the S-500 model, everything is much more interesting, by default it has the same dimensions of the working area, but 10 m higher, however, if desired, the site increases to 31, 0 × 11, 0 × 80, 0 m.This is not a typo, on the site of the manufacturing company, it is emphasized that using special fasteners to the facade of the building, it is possible to increase the height of the mortar lifts to 80 m and build mini-skyscrapers.
Complete with the construction printer itself, there is a station for the preparation and supply of concrete, which ensures the installation of structures at a speed of 2.5 cubic meters. solution per hour. The positioning accuracy of the print head is only 2 mm, the thickness of the print layer varies from 10 to 30 mm, and the width is 40-80 mm. According to the CEO of AMT-Spetsavia, Alexander Maslov, the business has long been making requests to create printers for fast and efficient printing of multi-storey buildings. Now such an opportunity has really appeared!
