Metal Powder Works Extends Westinghouse Nuclear Deal Into Third Development Phase
MPW advances Westinghouse partnership into third development phase
Metal Powder Works (ASX: MPW) has extended its Metal Powder Works Westinghouse nuclear partnership into a third phase of product development, continuing a multi-year collaboration with Westinghouse Electric Company (WEC). The new phase spans 3 months and focuses on further product optimisation and advancing the Technology Readiness Level (TRL) of WEC components under development. While the contract is not financially material, the MPW Board has characterised the ongoing strategic relationship with WEC as material, given the company’s standing as a global nuclear leader with its technology operating in 50% of the world’s nuclear plants across more than 70 years in the industry.

Why nuclear additive manufacturing is a high-stakes growth market
Additive manufacturing (AM) refers to the process of building precision components layer by layer using metal powder feedstock, commonly known as 3D printing for industrial applications. Within the energy sector, nuclear has emerged as the fastest-growing AM sub-sector, driven by two compounding forces: urgent spare parts demand for ageing reactor fleets and an accelerating pipeline of small modular reactors (SMRs).
Industry specialists at VoxelMatters noted in January 2026 that the nuclear sector is approaching a point where AM is embedded into regular supply chains, not merely used for prototyping or one-off components. For MPW, this trajectory positions the company as a foundational supplier of the metal powder feedstock that makes nuclear AM possible.
Market numbers that frame the opportunity
Key market figures investors should note:
- The nuclear sector is projected to exceed USD 40 billion in 2026
- Additive manufacturing material consumption in the energy sector is expected to exceed USD 800 million by 2034
- Nuclear is the fastest-growing AM sub-sector within energy
| Metric | Figure | Timeframe | Relevance to MPW |
|---|---|---|---|
| Nuclear sector market size | USD 40 billion+ | 2026 projected | Expanding total addressable market for nuclear component suppliers |
| AM material consumption (energy sector) | USD 800 million+ | By 2034 | Growing demand for metal powder feedstock across energy AM applications |
| Nuclear AM sub-sector growth | Fastest-growing segment | Current trajectory | Positions MPW’s powder supply capability in the highest-growth niche |
| Nuclear AM supply chain maturity | Near embedded adoption | 2026 (VoxelMatters) | Suggests near-term shift from development contracts to regular procurement |
DirectPowder™ process earns continued confidence from a global nuclear leader
At the centre of MPW’s WEC engagement is the company’s patented DirectPowder™ process, which converts metal bar stock directly into high-quality, consistent powder feedstock for additive manufacturing, cold spray, and powder metallurgy applications, without melting or contamination. This non-thermal approach represents MPW’s core intellectual property and distinguishes its powder production from conventional methods.
The third phase of collaboration involves advancing and scaling powder production capability for WEC, improving end-product performance, and progressing the TRL of components currently under development. WEC’s decision to extend the agreement is a direct response to successful results achieved across the previous two phases, reflecting accumulated technical confidence rather than a speculative new commercial arrangement.
What WEC’s renewal signals to investors
WEC’s choice to proceed into a third phase is an indicator that MPW’s powder is performing to specification under one of the most demanding quality regimes in global manufacturing. Managing Director John Barnes stated:
John Barnes, Managing Director
“This follow-on contract with Westinghouse highlights the solid performance of our DirectPowder™ process and the hard work of our combined technical teams. This continued confidence from WEC highlights that our powder works as expected and can meet their exacting requirements, exceeding the capability of legacy atomized powder methods.”
The characterisation that DirectPowder™ exceeds “the capability of legacy atomized powder methods” is significant. It reflects WEC’s own technical assessment, lending third-party credibility to MPW’s core process claims.

What comes next for MPW and the Westinghouse program
Over the coming 3 months, the focus will remain on further optimisation and TRL advancement in support of WEC’s broader initiatives in advanced manufacturing and materials innovation for the nuclear energy sector. The work builds on a production portfolio that already spans 25+ powders, including high-strength aluminium, copper and copper nickel alloys, CP-Ti, and Zircaloy.
Third-party recognition reinforces MPW’s technical standing in this space. The company was named Material Company of the Year at the 2024 3D Printing Industry Awards and holds finalist status in the 2026 TCT Awards for Material Innovation. Both citations reflect an independently validated profile that complements the WEC relationship.
The strategic framing from the MPW Board is clear: financial materiality from this contract is not the primary consideration. What matters is the depth and continuity of the relationship with one of the world’s most respected nuclear energy companies, and what that relationship signals about the long-term trajectory of DirectPowder™ in advanced nuclear manufacturing.
