World’s First 3D-printed House Springs up in Russia in 24hrs

Believed to be the first house printed using mobile 3D printing technology, a 38-square-meter surface structure has sprung up in Stupino, Moscow.

“Printed” as a whole, rather than assembled from pre-printed panels, by Russian companies Apis Cor and PIK, construction took place at Apis Cor’s test facility, with casting of self-bearing walls, partitions and building envelope completed in less than a day — and the machine time of printing rated at 24 hours.

As it was erected in winter, the concrete mixture used as printing “ink” complicated matters. With concrete liquid only at temperatures above 41°F, a tent was erected over the construction to warm things up. The equipment itself, however, is able to operate in temperatures as low as -31°F. After completing the wall structures, the printer was removed with a crane. The use of new materials, such as geopolymer, in the near-future will allow printing at any temperature.

The Apis Cor 3D printing “arm” is reminiscent of a tower crane and is small, easily transportable and does not require detailed preparation before construction can begin, utilizing a built-in automatic horizon alignment and stabilization system. The printing process is automated and almost eliminates human error.

The mineral plaster used consists of white cement and ball-shaped marble and granite crumbs, offering heat insulation and combining well with thermal insulation systems, especially those such as mineral wool. The final finish is a thin-layer decorative plaster wall that does not require further insulation. The material is easy to work with and exhibits good hydrophobic properties.
