Record speed: GUtech Oman 3D prints three new buildings in just 8 days

GUtech in cooperation with COBOD has built 3 buildings in just 8 days in SEZAD, Oman. Now, the new promising economic zone has a 3D printed coffee shop, a public toilet and a Fisherman’s house.

  • The first 3D printed coffee shop in the world, a public restroom and a Fisherman’s house was 3D printed in respectively 22, 13 and 19 hours and the total duration including movements of the printer was 8 days.
  • A total of 173 m2 (1,851 SF) of buildings were made with a cost for the concrete of only 3,600 USD.
  • Nobody has 3D printed 3 new buildings on-site in just 8 days before; GUtech is documenting the potential of 3D printing with very fast project execution combined with using a minimal amount of labor and very low cost of concrete materials.
  • The new 3D printed buildings were made in Duqm, the Special Economic Zone of Oman, in cooperation with General Contractor Teejan and with the help of a construction printer from COBOD

GUtech, The German Technology University of Oman has impressed the world before when the organization back in December last year 3D printed the at that time largest 3D printed building of 190 m2 in real concrete with a cost of the concrete materials below 2,000 USD. Now GUtech is at it again, setting a new record for how fast 3D printed buildings can be erected:

Last week GUtech after just 8 days finished the 3D printing of not just one new building, but a complete selection of 3 new buildings made in Duqm, 540 km from the capital of Oman, where GU Tech is located. A performance nobody has matched before.

Dr. Yousuf Al Bulushi, GUtech said: “GUtech has introduced the 3D concrete printing in the sultanate of Oman and shows how we could adopt the newest construction technology and employ it so we can get the most out of it. With the record fast printing in Duqm we have proven the potential of 3D construction printing. We have a huge faith in our Omani expert team, and we are aiming to achieve beyond expected”

The first of the new 3D printed buildings was a world first in the form of a 3D printed commercial coffee shop with a floor area of 81 m2 (871 SF). The total printing time was 22 hours and the GU Tech team managed to finish the construction within three days, allocating eight hours of work per day. The construction has a height of 3,7m (12 feet). Materials consumption totaled 19,6 m3 of concrete made from 99% locally available raw materials and COBOD’s Dfab solution was developed in cooperation with Cemex.  

The second new building is a public toilet with a total area of 20m2 (215 SF). The total printing time amounted to 13 hours, divided into two days. The total height of the building is 3,5m (11 feet) and for this construction 10.6 m3 of concrete was used.

The last 3D printed building is a Fisherman’s house with an area of 72 m2 (775 SF). To complete the building, GUtech specialists needed only 19 hours of printing, divided into 2 days. This one-story house is 3m (10 feet) in height and to make the building 17,3 m3 of concrete was used.

All the 3D printed buildings were made in cooperation with Teejan, as a general contractor. The buildings were 3D printed with locally available raw materials and the Dfab solution developed by COBOD and CEMEX, which makes it possible to 3D print concrete with 99% locally sourced materials at a very low cost. In total, just 3,600 USD was used for the concrete for the 3 buildings. All buildings have load bearing walls with no columns, roof slabs and 3D printed parapets.

Duqm similar to NEOM in Saudi Arabia, is a new development area, based on several economic, tourism and development zones, which contains a multipurpose port, a dry dock for ship repairs, a fishing port, a regional airport and tourist, industrial and logistical areas. https://duqm.gov.om/en

The authorities of Duqm approved the 3D printed construction method and provided the permits for the 3D printed buildings. Zaid Marmash, head architect and responsible for the Middle East at COBOD said: “I am proud to have co-designed the buildings 3D printed by GUtech and approved in Duqm. With the use of curves and unconventional shapes, the buildings match the futuristic and aspirational nature of Duqm. 3D concrete printing, as well as Duqm, are both very promising, and GUtech is providing the proof that the promises are being realized.”

About COBOD International

COBOD International’s mission is to disrupt the global construction industry through world class multifunctional construction robots based on 3D printing systems. Faster. Better. Cheaper. COBOD International 3D printed Europe’s first building in 2017. Subsequently the first 2- and 3-story buildings in Europe, US, Canada, and India were made with COBOD’s technology. Also, the first villa in Dubai and the first buildings in Africa have been done by COBOD’s 3D construction printers, like the first wind turbine bases. We have an open-source strategy, partnering with customers, academic institutions, and suppliers around the world. COBOD’s headquarters are in Denmark with regional offices and competence centers in Miami, US and Kuala Lumpur, Malaysia. We have +100 highly competent pioneers from 25 nationalities and a truly global presence in Asia, Middle East, Africa, Europe, North, Latin and South America.
