Qatar launches world's largest 3D printed construction project to build public schools
The project involves the construction of 14 public schools, including two built using 3D printing technology, each with a built-up area of 20,000 square meters — totaling 40,000 square meters. This is 40 times larger than the largest 3D-printed building constructed anywhere in the world to date. The two schools are designed as two-storey buildings on plots measuring 100 by 100 meters each, making this project an unprecedented model for future-ready educational infrastructure in Qatar and across the region.
To realize this unprecedented scale, UCC Holding commissioned COBOD, the world leader in 3D construction printing based in Denmark, to supply two customized BODXL printers, each measuring 50 meters long, 30 meters wide, and 15 meters high—roughly the size of a Boeing 737 hangar—making them the largest construction printers in the world.
Following extensive preparation—including site development, equipment assembly, and operational simulations—printing operations have officially begun. UCC Holding has assembled a dedicated 3D construction team consisting of architects, civil engineers, material scientists, and printer technicians. Over the past eight months, this team conducted over 100 full-scale test prints using a BOD2 printer at a dedicated trial site in Doha, developing concrete mix designs, validating performance under local climate conditions, and engineering a custom print nozzle to ensure precision and smooth extrusion.
In May 2025, the team completed intensive training alongside COBOD engineers, covering printer operation, print sequencing, structural layering strategies, and live quality control. This milestone marks a major leap in Qatar's local capacity for advanced construction technology, solidifying its role as a regional hub for innovation and engineering.
Compared to conventional construction methods, 3D printing offers multiple environmental, social, and economic advantages. It significantly reduces raw material waste and minimizes concrete usage, cutting carbon emissions. On-site printing also reduces transport needs, mitigates supply chain risks, and accelerates project delivery. With operations scheduled at night to avoid high temperatures, the process also ensures better concrete performance while reducing dust and noise.
Architecturally, the schools are inspired by the natural desert formations of Qatar, with curved, flowing walls resembling sand dunes. This design is only made possible by the geometric freedom that 3D printing offers—enabling organic, parametric forms that would be difficult or cost-prohibitive using traditional construction methods.
The schools are expected to be completed by the end of 2025, reinforcing Qatar's global leadership in sustainable development, innovation, and next-generation public infrastructure.

Boeing workers threaten strikes as union rejects contract offer
Agencies Members of a union representing workers who assemble fighter jets at two Boeing facilities rejected the company's proposed new contract Sunday, opening the door for possible strikes. 'IAM Union members delivered a clear message: the proposal from Boeing Defense fell short of addressing the priorities and sacrifices of the skilled ... workforce,' the International Association of Machinists and Aerospace Workers (IAM) said in a statement. More than 3,200 union members employed at Boeing facilities in the Midwestern states of Missouri and Illinois rejected the company's contract to the union, their contract was set to expire at the end of the day on Sunday. The workers in IAM branch 837 will go on strike if no deal is reached with the aerospace giant in the next seven days. The move could deal a serious blow to the company, after a seven-weeklong walkout by Seattle-based workers last year crippled two of Boeing's major assembly plants. 'We're disappointed our employees voted down the richest contract offer we've ever presented to IAM 837, which addressed all their stated priorities,' said Dan Gillian, vice president of Boeing Air Dominance and general manager of the site in St. Louis, Missouri. In a statement sent to Agence France-Presse (AFP), Gillian said no talks were scheduled with the union and the company was 'preparing for a strike.' Boeing's proposal included a 20% pay hike over four years and more vacation members working at sites in St. Louis and Mascoutah, Illinois, felt it did not meet their needs and did not guarantee a 'secure future,' according to the union.

Indonesia to cut tariffs, ease critical mineral limits: US
Agencies The US tariff deal with Indonesia is set to ease critical mineral export restrictions from the Southeast Asian country to the United States, the White House said Tuesday, as President Donald Trump hailed a 'huge win' for companies. The deal, first announced last week, notably lowered a threatened US tariff on Indonesian products from 32 percent to 19 percent. Goods deemed to have been transshipped to avoid higher duties elsewhere, however, will be tariffed at 40 percent, a US official told reporters Tuesday. 'It is agreed that Indonesia will be Open Market to American Industrial and Tech Products, and Agricultural Goods, by eliminating 99 percent of their Tariff Barriers,' Trump said on his Truth Social platform. The US leader added that 'Indonesia will supply the United States with their precious Critical Minerals' and sign deals to buy Boeing aircraft and US agriculture and energy products. The country is a key producer of minerals like copper, cobalt and nickel. A joint statement separately released by the White House noted that, apart from the lower 19 percent tariff Indonesian goods will face, certain commodities not available in the United States could also be eligible for an even lower levy. 'Indonesia will remove restrictions on exports to the United States of industrial commodities, including critical minerals,' the statement added. Meanwhile, Indonesia will drop its effort to tax the flow of data, the US official said, speaking on condition of anonymity. The official called this a 'revenue grab' on US companies. The country will also remove pre-shipment inspection or verification requirements on US goods imports, and has agreed to accept US federal motor vehicle safety standards. Both countries are set to finalize the deal in the coming weeks, the joint statement said. Indonesia remains among the first of a surge in deals the Trump administration promised in recent weeks, ahead of a deadline for higher tariffs to take effect on dozens of economies come August 1. Washington had imposed a 10 percent levy on most trading partners in April and hiked duties on dozens among them — before postponing their imposition twice. Apart from Indonesia, the United States has announced pacts with Britain, Vietnam and the Philippines. Washington and Beijing also reached an agreement to temporarily lower tit-for-tat tariffs on each other's products, although the pause is due to expire in mid-August. The US official said the Indonesia deal was 'worth at least $50 billion' to the United States in terms of new market access and purchases that Indonesian companies intend to make.
