A TRUE LANDMARK

The house consists of 190 m2 (2,100 SF) and is typical for a social housing unit in Oman. It has 3 bedrooms, three bathrooms, a living room, kitchen, and guest reception area. The house was printed in two stages. While the materials recipe was adjusted and training of the Omani crew took place during the printing of the first part of the house.

REVOLUTIONARY COST-SAVINGS

The world’s largest 3D printed real concrete building was printed with the low-cost D.fab concrete solution developed in cooperation between CEMEX and COBOD. In the case of Oman, more than 99.5% of the materials used were local, with less than 0.5% coming from Europe in the form of the D.fab additives. In Oman, the cost of materials for 3D printing the walls of the 190 m2 (2.100 SF) house was less than 1,600 euros. According to COBOD, if a printable dry mix mortar had been used, the cost of the materials would be more than 20,000 euros, and it was such significant cost reductions that COBOD and CEMEX were aiming for with their cooperation.
