A new school in Qatar with 3D printed concrete walls is close to completion, 3Dnatives reports. The builder, UCC Holding, says the roof, windows, doors and interior finishes are now going in, and the project has been described as the "largest 3D printed building ever constructed."
The numbers are huge:
- Printing began in June 2025 with a COBOD BOD XL, a concrete printer 50 meters long, 30 meters wide and 15 meters high.
- The school's 3D printed walls cover 30,000 square meters, with more than 500 kilometers of printed layers.
- The printer was taken apart, moved and rebuilt 15 times to reach every part of the site.
- Printing happened at night to protect the fresh concrete from the daytime heat.
It's one of 14 new public schools announced, and one of two being built with 3D printing. Its walls curve like the dunes of the Qatari desert, a shape that would be hard and costly to build the usual way.
Kid connection: it's the same idea as the printer on your table. A nozzle lays down one thin layer, moves up a little, and lays down the next, whether it's a keychain or a school.
