LAMÁQUINA’s 3D printed ceramic tiles complete Sagrada Família’s tallest tower Construction 3D Printing

by Architecture

On February 20, 2026, the final arm of the cross was lifted onto the Tower of Jesus Christ at the Sagrada Família in Barcelona, marking the completion of the cathedral’s exterior and the culmination of 144 years of construction. The cross now crowns the structure at 172.5 meters, making it the world’s tallest church. The robotic 3D printed ceramic tiles that form the tower’s white glazed ceramic skin were developed by LAMÁQUINA in collaboration with Ceramica Cumella.

Sunnyday Technologies releases M3-CRETE open-source 3D concrete printer 3D Printer Hardware

by Architecture

Sunnyday Technologies is releasing M3-CRETE, a fully open-source concrete 3D printer built for field deployment and research validation. The project sits alongside CEMFORGE, Sunnyday Technologies’ AI-driven concrete formulation platform, which the firm positions as a mix-design engine for additive construction. Sunnyday Technologies publishes documentation, CAD files, and a draft bill of materials (BOM) to a public GitHub repository for customization and comment.

3D printed pool makes a big splash in Australia Construction 3D Printing

by Architecture

While an outdoor swim might seem like a far-off dream to those of us trying to warm up in the Northern Hemisphere, it’s an essential cool-down tactic for Aussies at this time of year, with summertime temperatures in Western Australia soaring above 30°C. Most in the region will be doing their laps in standard in-ground pools, but soon a small number of locals will be able to say they’re swimming in the country’s first 3D printed pool.

Two-story 3D printed home passes Japan’s stringent seismic standards Construction 3D Printing

by Architecture

As a country that experiences upwards of 500,000 earthquakes every year, Japan is correct to have highly stringent building requirements. These requirements—the New Anti-seismic Structure Standard from 1981 in particular— ensure that only buildings with earthquake-resistant structures are erected. In a milestone for the emerging construction 3D printing sector, the first two-story 3D printed home has been approved by Japan’s government based on these standards, demonstrating that reinforced 3D printed concrete is a valid construction material for earthquake-resistant homes.

Cornell team advances underwater 3D printing of concrete project Industrial Additive Manufacturing

by Architecture

A team of interdisciplinary researchers at Cornell University is making significant progress in a bid to successfully 3D print concrete underwater, in response to a project call from the Defense Advanced Research Projects Agency (DARPA) issued in the fall of 2024. The challenge was for proposals to meet a deadline to design 3D printable concrete that can be deposited at depths of several meters underwater within a year.
