Engineers Create a World-First in Floating Titanium

3D-printed foam-filled titanium stays afloat despite cracks

A titanium structure that lets water pass through its openings could offer a new approach to building buoys, jetties and floating sensors. Researchers led by RMIT University have developed a foam-filled metal lattice that floats despite damage and outperforms common marine materials at the same overall density. The study describes a 3D-printed framework of hollow, interconnected titanium struts filled with polyurethane foam. Samples remained afl…

Scientists Just Built The First Titanium Frame That Floats

Engineers built the first open metal frame that floats, thanks to a titanium-and-foam design that survives cracking and crushing.

Australian researchers create floating titanium metamaterial

Australian researchers have built a 3D-printed titanium structure that floats in water and keeps floating even after significant damage, according to a study led by RMIT University. The material is a lattice made of hollow, interconnected titanium struts filled with polyurethane foam. Researchers said it withstands seawater exposure and is stronger than the stainless steel […]

Floating Titanium Lattice Could Out-Perform Steel and Plastic

Australian engineers have created a strong and lightweight titanium material that floats in water, even after severe damage, revealing a promising new material for marine infrastructure.Research led by RMIT University shows the 3D-printed titanium lattice – made up of hollow…

Engineers create a world-first in floating titanium

Research led by RMIT University shows the 3D-printed titanium lattice—made up of hollow, interconnected struts filled with foam—not only floats but also withstands seawater exposure and is stronger than the stainless steel or high-density plastic currently used in jetties, buoys and floating sensors. The paper is published in the journal Advanced Materials.
