Holcim with assistance from PERI completed the printing of Switzerland’s first 3D printed building, a 150 m2 (1614 SF) showroom, in just 55 hours over 8 days.
The 3D printed mainly curved walls, reaching 6.2 meters (20.3 feet) in height, contained 60m3 of concrete.
By using a new developed real concrete mix by Holcim, with less cement and more strength than the mortars primarily used by other printers, Holcim’s focus was both on sustainability and durability, reducing environmental impact and enhancing structural integrity of the building.
