Australia’s housing crisis may not be solved with bricks and mortar but with plastic waste.

Inside a West Australian industrial shed, a machine the size of a small room is quietly printing what could become the future of housing, the Southern Hemisphere’s first 3D-printed recycled plastic tiny home.

“There’s a lot of plastic in Australia that can be turned into a construction resource,” Hyperion co-founder Josh Wigley says.

Hyperion found its roots in 3D-printed boats from recycled ocean plastic, where it invested time and money in extensive research and development.

Through that journey, it has evolved into a materials and manufacturing business and is targeting one of Australia’s most entrenched challenges: tackling a chronic housing shortage.

“We started in 2022 with the idea of 3D printing boats using recycled ocean plastic,” he says. “And the first couple of years were about building that first machine—and printing a boat. It floated.”

That early proof point became a foundation for something broader: a large-format additive manufacturing platform now being applied across marine, architecture and, now, housing.

The company has just inked its first deal to develop a tiny home prototype, alongside builder Little Castles.

The collaboration is designed to test both technical and commercial feasibility. Hyperion prints the shell, while the builder handles fit-out.

Manufacturing company disguised as a startup

From the industrial innovation hub of Henderson, about 30km south-west of the WA capital, the company now operates a network of machines— six in Perth and three on Australia’s east coast—alongside containerised units that can be deployed almost anywhere.

“We scaled desktop 3D printing into a 9m x 3m large-format printer,” Wigley says.

“We realised we’d built capability across hardware, software, materials and design for additive manufacturing.”

That capability has since been consolidated into a vertically integrated production system of machines, software, materials processing, and design.

The pivot from boats to housing

The shift into housing wasn’t a sudden strategic rebrand. It was a by-product of material science, logistics and a growing awareness of construction inefficiencies in the market, according to Wigley.

“We realised this technology can be used for housing—and there’s a lot of plastic in Australia that can be turned into a construction resource,” he says.

▲ Hyperion co-founder Joshua Wigley says the research and development has been critical to the move into 3D-printed homes.

At the centre of that opportunity is polymer.

Unlike concrete-based 3D printing systems, Hyperion’s approach relies on lightweight recycled plastics that can be prefabricated in controlled factory environments before being transported to the site.

“Using polymer instead of concrete means the structures are lightweight enough to prefabricate in a factory,” he says. “With concrete printing, you’re forced on-site—wind, rain and logistics become major constraints. We avoid all of that.”

Wigley says the process is relatively simple. A digital model is sliced into layers, converted into a toolpath and fed into the machine, which deposits material layer by layer until a physical structure emerges and hardens within 48 hours.

The material problem: waste as feedstock

The true innovation in Hyperion’s story is its research on plastic reuse and its identification of viable waste streams.

The company began with virgin plastics to stabilise its early R&D. It has since moved into recycled and post-industrial streams, largely sourced from Western Australia’s resources and manufacturing sectors.

“The biggest issue with recycling is getting a clean, consistent single-stream source,” Wigley says. “That’s what makes it difficult to scale.”

Early experiments even relied on imported recycled plastics from Europe due to limited local supply chains.

That constraint pushed Hyperion toward vertical integration.

“We invested in our own processing capability—that’s what really changed the game for us,” Wigley says. “It was risky, but it gave us sovereign capability.”

The company now compounds its own materials—blending polymers with additives to achieve specific structural, thermal and fire-resistant properties.

“We’re now sourcing polyolefins from post-industrial streams within WA’s manufacturing and resources sector,” he says.

Building code reality check

But the most persistent challenge for Hyperion remains regulatory.

“The biggest shift for us in housing is getting the material through building codes—that’s where all our R&D is going,” Wigley says.

Hyperion is working closely with the University of Western Australia to validate material performance, particularly fire resistance, UV stability and long-term durability.

“We’re doing a lot of work with UWA on building code compliance and material properties,” he says.

That includes accelerated UV testing, thermal modelling and real-world stress testing in extreme environments across Western Australia.

“We’ve got components out at Kalgoorlie performing well,” he notes. “And HDPE (high-density polyethylene) boats built 30 years ago are still operating today.”

Speed, structure and a new construction model

“We’re not the builder—we’re the manufacturing agent producing the shell while builders work in parallel,” Wigley says.

“We see a distributed manufacturing network across Australia,” he says. “Multiple facilities working with builders rather than one centralised factory.”

Wigley says the system could reduce fit-out time by 20 to 30 per cent.

“But we’ll back that with physical numbers as projects progress,” he says.

The homes themselves are evolving in design flexibility. Current systems can produce rooms up to six metres by four metres, with scalability built into the machine architecture.

“We’ve designed the tech so it can expand easily,” he says. “It just depends on demand and the business case.”

Housing, climate and construction pressure

Wigley says there is a big opportunity in developing low-cost, rapid-production housing.

He also sees applications in the more complex remote and regional Australia markets, where logistics and labour shortages compound delivery challenges.

“Remote housing in northern Australia is a major opportunity,” he says. “We’re already deploying containerised machines in those regions.”

Hyperion has just sold its first unit to an Indonesian island, which Wigley says is testing that idea of remote, distributed manufacturing infrastructure.

The company is also exploring paired systems—combining printing units with micro-recycling plants to process waste locally.

“You could have a microprocessing facility alongside a microfactory,” he says. “Tapping into local council waste streams and localising production.”

Scaling out, not up

For Hyperion, growth is not just about larger machines or bigger homes. It is about replication.

“We’re building more machines in Henderson to support these projects,” Wigley says.

“And increasing recycling and processing capability so we can scale.”

International expansion is already under way, with interest emerging from the Indo-Pacific and US markets.

Capital raising is also on the horizon to support that expansion, Wigley says.

“We’re open to working with anyone who has a problem this technology might solve,” he says.
