Australia Backs AM Research Push

Australia's Additive Manufacturing Cooperative Research Centre has approved its first five industry-led CORE projects, moving the national program from funding architecture into applied industrial research. The projects unlock more than AU$11 million in combined investment, including Commonwealth support, matched industry funding, and substantial in-kind contributions from research and commercial partners.

The scope is broad, spanning aerospace, mobility and transport, medtech, mining, and defence. That breadth matters because it frames additive manufacturing not as a single-machine story, but as a production capability tied to advanced materials, sustainable design, qualification, and high-performance manufacturing.

The signal for the AM sector is clear: public funding is being paired with industry-led problems and commercial deployment pathways. The CORE program is intended to move technologies from proof-of-concept toward pilot production, where material data, process control, post-processing, and certification become as important as the printed geometry itself.

For a field often judged by isolated demonstrations, the Australian program reads like a shift toward systems-level adoption. The coming test will be whether the projects can translate AM research into qualified, repeatable manufacturing workflows that industry can trust at scale.

Research Spotlight

M. Pozzi and co-authors — The European Physical Journal Special Topics

This paper is the strongest fit for today's scope because it links PBF-LB/M copper, surface engineering, and functional performance. The reported two-step vibro-finishing route reduces roughness from the as-built state to sub-micrometric values, underscoring how surface post-processing can be decisive for demanding AM applications.
