Armada Technologies, a Liverpool-based firm on a mission to reduce the environmental impact of global shipping, turned to 3D People to manufacture a critical part for its revolutionary Passive Air Lubrication System (PALS).

(13th January 2026, London, U.K.) A small 3D printed component is making a big impact beneath the hull of an Liquid Natural Gas (LNG) carrier, and it's London-based 3D People that helped bring this engineering innovation to life. Armada Technologies, a Liverpool-based firm on a mission to reduce the environmental impact of global shipping, turned to 3D People to manufacture a critical part for its revolutionary Passive Air Lubrication System (PALS).

PALS is a transformative technology that reduces drag by releasing microbubbles beneath a ship's hull, creating an aerated layer that cuts fuel consumption and emissions. Unlike traditional systems that rely on energy-hungry compressors, Armada's design uses the vessel's own forward motion to draw air through a proprietary venturi ejector. But producing that ejector (a precision geometry exposed to extreme pressures, corrosive seawater, and continuous flow) posed a major manufacturing challenge.

Traditional methods couldn't deliver the required internal features, surface uniformity, or environmental durability. Industrial additive manufacturing, however, offered the perfect solution, and Armada needed a partner with both capability and engineering intelligence.

"3D People stood out immediately," said Armada COO Roger Armson. "They understood the complexity of the part, grasped our technical needs quickly, and delivered prototypes that met our stringent functional and compliance requirements."

Using PA12 Nylon for its strength and marine resilience, 3D People produced the components via SLS and used vapour smoothing to ensure optimal fluid interaction. Over four production batches, every part met Armada's tight timeline and quality thresholds. Eight months after installation, the components continue to operate flawlessly.

For 3D People, the project reflects the real potential of industrial 3D printing.
"We love projects where additive manufacturing isn't just convenient, it's transformative," says Sasha Bruml, Co-Founder of 3D People. "Working with Armada shows how AM can unlock sustainable engineering solutions that simply wouldn't be possible any other way."

Co-Founder Felix Manley adds, "This is exactly where 3D People excels, complex parts for demanding environments, and customers who value engineering collaboration. Our role isn't just to print parts, but to help solve problems."

As global industries push toward cleaner, more efficient technologies, the collaboration demonstrates how agile, production-grade 3D printing can accelerate innovation in even the harshest operating environments.

"As sustainable technologies scale and engineering challenges become more complex, partnerships like this show why additive manufacturing is now integral to modern industrial problem-solving," Bruml adds. "3D People has spent years building the expertise, precision, and reliability that projects like Armada's demand, and we will continue to be the partner innovators turn to when performance truly matters."
