Australia’s defence push goes 3D, and this ASX stock has a head start

• $2.7m project to boost Aussie-made defence components
• Aurora Labs eyes bigger role in defence manufacturing
• Certification and $1m grant boost Aurora’s ambitions

Australia wants to build its own military hardware. But there’s a catch.

You can’t build the big-ticket weapons without the specialised components that make them work. And that’s where a new push into advanced manufacturing could open up some serious opportunities.

A new $2.7 million industry-led project announced this month aims to boost Australia’s ability to manufacture critical metal components locally.

The goal is to meet the tough standards demanded by defence, maritime and medical industries.

Led by Stärke-AMG and Flinders University, the four-year initiative will develop the manufacturing processes, technical data and quality frameworks needed to produce qualified 3D-printed metal components in Australia.

Adelaide University and Metal Powder Works are also bringing their expertise to the table.

The idea is simple.

It’s one thing to produce an impressive prototype.

It’s another to make something that can actually be approved for use in a submarine, aircraft or other demanding application.

The big hurdle for metal 3D printing

Metal 3D printing, also known as additive manufacturing, works by building components layer by layer instead of carving them out of a solid block of metal.

It’s a clever way to make complicated shapes, cut down on wasted materials and potentially avoid the headache of waiting for components to arrive from overseas.

Sounds great on paper, but getting those components approved for defence use is a whole other story.

Just because something comes out of a printer looking the part doesn’t mean a defence contractor will happily stick it inside an aircraft or warship.

Manufacturers still need to prove their processes are reliable, their materials meet strict specifications and they can produce the same quality components again and again.

That’s exactly the problem the new $2.7m initiative is trying to solve.

And for investors, the story goes well beyond one research project.

If Australia wants to stop relying so heavily on overseas suppliers, it’s going to need local manufacturers that can deliver properly qualified components, consistently and at a commercial scale.

That’s where things start getting interesting for ASX-listed companies already building those capabilities.

Aurora Labs’ bigger opportunity

One company already making moves in this space is Aurora Labs (ASX:A3D).

The Perth-based company is probably best known for its metal 3D-printing technology and its work developing micro gas turbine propulsion systems for defence applications.

But there’s more to Aurora than engines.

It’s also working to establish itself as a manufacturer of specialised metal components for aerospace, naval sustainment and the broader defence industry.

Its FY26 annual report highlighted work with QinetiQ Australia involving printed components for operational naval asset sustainment.

Aurora has also been accepted into the Australian Submarine Agency’s Defence Industry Vendor Qualification program, an important step along the road towards qualifying for submarine sustainment work.

And the timing is interesting.

Australia’s long-term AUKUS commitments mean the country will need to support and maintain increasingly sophisticated naval equipment for decades to come.

Long Shortz with Aurora Labs: MBDA partnership marks major defence milestone

Submarines and warships don’t exactly get replaced every few years.

They can stay in service for decades, and keeping them operational means having access to replacement components, sometimes long after the original manufacturer has stopped making them.

That’s where advanced metal printing could come in handy.

Instead of waiting for a hard-to-find component to be shipped from the other side of the world, certain parts could potentially be manufactured locally, provided they meet the necessary technical and quality requirements.

For Aurora, that opens up the possibility of building a business that goes beyond propulsion systems and into supplying specialised components and manufacturing services.

Aurora ticks the boxes for its next big move

Aurora ticked an important box in August when it achieved AS9100D certification.

This is an internationally recognised standard that shows customers Aurora has the right quality controls to meet the tough demands of aerospace and defence.

Aurora has also secured a $1m Defence Industry Development Grant, which it’s matching with its own contribution, to help fund new industrial metal-printing equipment.

“As we move into the next phase of our development, our focus is increasingly on converting that foundation into scaled manufacturing programs, strategic partnerships and commercial outcomes,” said Aurora chairman David Trimboli.

That push comes as Andrew Garth takes over as CEO, bringing more than 20 years of experience across defence, aerospace, advanced manufacturing and government.

Meanwhile, former CEO Rebekah Letheby has moved into the COO role.

For investors, the bigger opportunity is whether Aurora can turn its technology into repeat orders from defence customers.

Its three-year agreement with European missile giant MBDA shows it’s already building relationships, but the real test is turning those opportunities into steady commercial revenue.

Other ASX stocks in this race

Aurora isn’t the only ASX player making moves in metal 3D printing.

AML3D (ASX:AL3) has been making inroads into the US defence supply chain with its large scale metal 3D-printing technology.

In March, it announced an order of approximately $2.6m to manufacture replacement components for US Navy submarines.

Titomic (ASX:TTT) is another Australian advanced manufacturing player using cold-spray technology to build and repair metal components for industries including defence and aerospace.
