France completes Europes largest 3D printed housing block

Published on May 28, 2026 | Translated from Spanish

In France, a 12-apartment building constructed with 3D printing has been completed, marking a milestone in European construction. The structure was finished in just 34 days of printing, three months less than a traditional project, using half the workers and generating less waste. The project demonstrates that technology can accelerate timelines without sacrificing quality. 🏗️

Less concrete, more efficiency: the technical details of the project 🔧

The printing required three operators compared to the usual six, and waste dropped from 10% to 5%. The curved geometry of the walls saved 10% of concrete. The building incorporates perlite insulation, solar panels, and a hybrid heating system, achieving 60% energy self-sufficiency. A similar building constructed conventionally confirmed that time was cut in half.

Bricklayers see the printer and ask for an iced coffee ☕

While traditional bricklayers sweated bullets for 50 days, the 3D printer finished its job in 34. Of course, no one has yet seen the machine complain about the heat, ask for a raise, or knock off mid-afternoon. For now, the only ones protesting are the neighbors, who fear the next step will be printing impossible rents.
