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

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.
November 2022 – GUtech, The German Technology University of Oman has impressed the world before when the organization back in December last year 3D printed the 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 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 COBODs 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 Fishermans 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.
