It was important for us to create a precedent, to show in practice that 3D construction technology is working, " says Alexander Maslov, general director of the AMT Group, managing the construction. - at that time to print the house - it was something from the realm of fantasy. We set the task to make it real. To paraphrase the words of the famous song, they took a fairy tale to make byl. Printing was done in the shop on the smallest printer. Printed the building in parts (the walls of the house, decorative elements, the tower), were taken to the construction site and collected as a designer. Since then, of course, the equipment has been improved: the speed of printing has improved, and the quality has improved. But even our first model showed itself as a reliable and efficient equipment . "
For printing used construction printer S-6044, serially produced by AMT-SPETSAVIA. This model is a portal type with a working field of 3.5 x 3.6 x 1 m. The printer prints standard M-300 sand concrete, i.e. that can be purchased in almost any store building materials. Printing is done with layers 10 mm high and 30 to 50 mm wide. The speed of printing walls is up to 10 sq.m / h.
