Austria’s first 3D printed building is being constructed in Hausleiten, Lower Austria. Construction technology group Strabag, together with Peri, is realising a roughly 125 m2 office building next to its asphalt mixing plant in Hausleiten. The pure printing time for the building extension is approx. 45 hours. The special dry mortar for the construction 3D printing project is being supplied by Lafarge.
"3D construction printing brings an important innovation impulse for the construction industry and is an exciting addition to other construction methods. With this practical test, we want to further develop 3D construction printing together with our partners Peri and Lafarge. In Hausleiten, we were already able to achieve important findings for future use during the joint planning," says the Strabag board member responsible for digitalization and innovation, Klemens Haselsteiner.
"At Peri, we see great potential in the still young technology of 3D construction printing. Just under a year ago, we printed Germany's first residential building with a Bod2 printer from our Danish partner Cobod. Now, together with our partners Strabag and Lafarge, we are bringing this new form of construction to Austria and are delighted with the first printed office building in Hausleiten," says Thomas Imbacher, Chief Innovation & Marketing Officer at Peri AG.
Peri is using the Cobod Bod2 gantry printer for the printing project in Hausleiten. With this technology, the print head moves over three axes on a permanently installed metal frame. The advantage: The printer can move to any position within the construction and only needs to be calibrated once.
With the printing project in Hausleiten, the PERI 3D construction printing team has successfully completed five printing projects in one year. All these projects are not research projects, but "real" houses that have gone through all the building code approval processes, are rented out and occupied, or in which people work.
