France's 3D-Printed Apartment Building, Europe's Largest, Completed in Just 34 Days

France has completed Europe's largest 3D-printed residential building, with walls and load-bearing structures built in record time — just 34 days. A specialized printer created the structure layer by layer directly on the construction site. Developers believe this new technology could make affordable housing faster and more efficient in the future.

France has completed Europe's largest residential building constructed using 3D printing technology, with the structural components — walls and load-bearing structures — finished in record time of just 34 days. The building was constructed using a specialized large-scale printer that layered material directly on the construction site.

3D printing has previously been used to construct individual homes and smaller buildings, but the technology has now reached a level where it can build full-scale apartment buildings. The French project represents a significant advancement and demonstrates that layer printing is suitable for larger and more complex structures.

According to the developers, this approach is considerably faster and more efficient compared to traditional construction. Since walls and load-bearing structures are printed on-site automatically, the need for large amounts of labour is reduced and construction time is cut dramatically. This could help address housing shortages in the future and make apartment construction more affordable.

According to experts, wider use of 3D printing in the construction sector also offers environmental benefits, as material waste is reduced and the process is more precise. Although the technology is still relatively new and faces several regulatory and technical challenges, the French project suggests that automated construction could become the new standard in the sector in coming years.
