Austria: PERI and STRABAG have used a COBOD 3D printer to successfully build Europe’s first 3D printed office building in Hausleiten, Lower Austria.

PERI board member for innovation and marketing Thomas Imbacher said "The building in Hausleiten is a milestone for STRABAG, for PERI, for all involved. We are convinced that 3D printing of buildings will be part of the future of construction, as this technology offers solutions for challenges that are currently occupying our industry: digitalisation, efficiency, shortage of skilled workers and much more."

US: COBOD says that construction of the largest 3D printed building in the US using its 3D printing technology has commenced at a site in Houston, Texas. The building is the country’s first two-storey residential building constructed using the method. PERI handled the order for contractor CIVE and architect HANNAH.

CIVE president Hachem Domloj said “Having the opportunity to be the engineers and general contractor for the first two-storey 3D printed structure in the US has been an honour. We can see how this technology and our team’s approach is providing the scalability to larger commercial developments. Collectively, we're changing the way our country builds, and paving the way for more affordable housing, higher structural integrity and faster building capabilities. The possibilities of 3D printing are endless!”
