World’s Largest 3D Printed Real Concrete Building In Muscat
Dubai was a leader in 3D construction printing for many years, but now that position is being challenged by Oman, which has printed the world's largest 3D printed real concrete building with a super-low cost of printed materials. The German University of Technology in Oman, GUtech, has completed the 3D printing of the walls of the world's largest 3D printed concrete structure on December 14, 2021. His Excellency Sultan Al-Habsi, Oman's Minister of Finance, attended the event, as did more than 200 guests, including many ministers and VIPs from Oman. The house is typical of a communal housing unit in Oman, with a floor area of 2,100 square feet. There are three bedrooms, three bathrooms, a living room, a kitchen, and a guest reception area in this home. Two stages of printing were used to create the house. While the materials recipe was changed and the Omani crew was trained during the printing of the first portion of the house, the Omani crew completed the second part of the house on their own in only five days. In 3D printed projects, this is a sign of rapid learning and productivity gains. More than 99.5 per cent of the materials utilised in Oman were indigenous, with the D.fab additives accounting for less than 0.5 per cent of the total. Material costs for 3D printing the walls of the 2,100 square feet house in Oman were less than 1,600 Euro. According to COBOD, the materials would have cost more than 20,000 Euro if a printable dry mix mortar had been used, and it was such huge cost reductions that COBOD and CEMEX were looking for with their collaboration.
