Brooke, who was recently awarded a Research Translation Fellowship at RMIT to accelerate the commercialization of this innovation, believes 3D-printed titanium alloys are on the verge of a major leap forward.

“3D printing enables faster, more efficient, and customizable manufacturing,” he explained. “Yet we’re still using outdated alloys like Ti-6Al-4V, which limit our ability to fully harness these advantages. It’s like building an airplane but only using it to drive down the road.”

He added, “By designing new titanium and other alloys, we can unlock the full potential of additive manufacturing. Our study lays the groundwork for doing just that.” Figure 1 shows High-Strength Titanium.

A Smarter Way to Design Alloys

The RMIT team’s research introduces a streamlined strategy for selecting alloying elements—cutting down both time and cost. This approach maximizes the benefits of 3D printing while improving material quality [1]. Their model also offers a better way to predict the grain structure of metals formed through additive manufacturing.

Unlike many 3D-printed metals that develop column-like grain structures—leading to inconsistent mechanical properties—the new alloy prints more uniformly, ensuring consistent strength throughout.

“We tackled two major obstacles limiting the wider use of 3D printing—cost and material consistency,” said Brooke. “By eliminating columnar microstructures and lowering production costs, we’ve made a significant breakthrough.”The new titanium alloy, whose exact composition remains confidential for commercial reasons, is 29% cheaper to manufacture than traditional titanium alloys.

Industry Feedback and What Comes Next

Brooke, who recently engaged with stakeholders in aerospace, automotive, and MedTech sectors through CSIRO’s ON Prime program, said the feedback was clear.

“Industry isn’t interested in small improvements—they want game-changing innovations. That’s exactly what we’ve delivered: a titanium alloy that’s not only cheaper but also stronger, more ductile, and structurally consistent.”Professor Mark Easton, the study’s corresponding author, said RMIT’s Centre for Additive Manufacturing is now actively seeking industry collaborators.

“We see tremendous potential in this alloy, but to bring it to market, we need a coordinated effort across the supply chain,” Easton noted. “We’re eager to partner with organizations that can help shape the next phase of development.” The alloy samples were produced and tested at RMIT’s state-of-the-art Advanced Manufacturing Precinct.
