3D-Printed Concrete Buildings Open at Saudi Arabia's ADRENA Resort

A resort that was printed, not assembled

The Red Sea destination in Saudi Arabia opened ADRENA, an adventure and entertainment district, to the public in March 2026. The project was officially completed on May 19. What makes it notable is that Artificial Engineering, a Saudi company, 3D printed the buildings in concrete. The entire district went from digital file to physical structure in roughly two months, with the full resort finished in under three.

EXP Arabia, a joint venture between global engineering firm EXP and Saudi group Al Suwaiket, handled engineering and design. Artificial Engineering's team handled the actual printing. That division of labor is worth noting. The design and engineering pedigree behind the project is conventional. The production method is not.

Why curved forms need 3D printing

ADRENA is built around curved walls and flowing spaces. Those shapes are intentional, not decorative. The curves guide visitor movement and soften the transition between buildings and the coastal landscape. Building those forms with conventional formwork would require custom molds for every section, significant material waste, and extra labor to remove the forms after curing.

3D concrete printing eliminates most of that. A specially formulated cementitious mixture is extruded layer by layer directly from a digital file, with no formwork needed. The material has to be fluid enough to pass through the nozzle without clogging, yet set fast enough to support the next layer before the previous one collapses. That balance is what separates working 3D concrete printing from a laboratory curiosity.

Artificial Engineering runs two types of equipment: a robotic arm for detailed custom geometries, and a gantry system for larger structural elements. The company also uses its own dry mix, blending cement, pigments, and additives in house. Controlling the material formulation alongside the printing hardware is a practical advantage. Most 3D concrete printing failures come from mismatches between the machine and the mix.

From one project to a business

Artificial Engineering describes itself as Saudi Arabia's first factory dedicated to concrete 3D printing. It also completed a phase at King Salman Park in Riyadh, producing service capsules. Those figures come from the company itself and have not been independently verified, but the ADRENA project is publicly accessible and confirmed.

The broader context is Saudi Arabia's Vision 2030 giga-projects. They are giving concrete 3D printing exactly what the industry has lacked: large, real contracts instead of trade-show demonstrations. Demand at this scale is moving 3D concrete printing from a novelty to a construction service that can be ordered by the square meter.

The ADRENA site also runs entirely on renewable energy, uses lighting designed to reduce skyglow, and incorporates a closed-loop seawater system. The 3D printing was not an aesthetic choice. It was a sustainability tool. Extruding only as much concrete as needed cut waste compared to traditional formwork methods. That is the case the industry has been trying to make for years. ADRENA is a real-world example of it working.
