Oman: World’s Largest 3D-Printed Real Concrete Building Is Completed

A team comprised of Danish 3D printer maker Cobod, Mexican cement company Cemex and the German University of Technology in Oman (GUtech) has produced the world’s largest 3D-printed building using real concrete.

The 190 sq. m structure is designed as a typical Oman house, with three bedrooms, a living room, kitchen and reception area.The concrete used for the house’s walls cost €1,600, with Cobod saying the printable dry-mix mortar usually used in printed buildings would have cost upwards of €20,000.

Work on the development took place over two stages, the first of which focused on the training of the Omani crew and fine-tuning of the concrete recipe, followed by it construction over the course of five days
