Freemelt has received a prototype order from an unnamed defence company operating in Sweden. Announced on 13 October 2026, the agreement funds a feasibility study in which Freemelt will produce several refractory-metal geometries for testing and evaluation. Order value, alloy, component function and customer identity were not disclosed.

The order, study scope and multiple test geometries are verified through Freemelt and Nasdaq Nordic disclosures. Improved component performance, shorter development cycles and a scalable resilient supply base are project aims. No serial-production contract, military qualification or field suitability has been established.

Why E-PBF for refractory metals

Freemelt uses electron-beam powder-bed fusion. An electron beam operating in vacuum provides high energy density, while powder-bed preheating can reduce residual stress driven by steep thermal gradients. Those characteristics may help with high-melting, brittle or oxygen-sensitive materials such as tungsten and selected niobium-, molybdenum- or tantalum-based systems.

The process does not make manufacturing simple. Powder chemistry, oxygen pickup, particle structure, beam focus, preheat, layer conditions and scan strategy influence density, cracking, evaporation, surface and microstructure. A successful coupon does not establish reproducibility across machines and lots.

The study's real question

Freemelt says the work goes beyond asking whether an existing part can be printed. Digital design, material and process may change together to improve function. That could mean heat-flow-oriented internal geometry, mass reduction, local stiffness or shapes difficult to make through conventional machining and powder metallurgy.

Performance-led redesign changes the qualification object. Dimensional inspection alone is insufficient: material properties, defect population, surface, heat treatment, load direction and life must be considered together. Defence confidentiality may legitimately limit public data, but it also limits external verification.

Connection to tungsten and fusion programmes

In September, Freemelt received a production order for more than 30,000 tungsten-based components for Fusion for Energy, followed by a separate development contract. That does not validate the new defence geometries, but it shows an attempt to connect material and process development with industrial delivery rather than only sell research equipment.

This feasibility study is therefore meaningful but still early evidence. The next levels are a measurement plan, customer-accepted results, a proof of concept and a qualified repeat lot. Freemelt's earlier programmes suggest that progression can require separate contracts and a long material-qualification cycle.

Safety and supply resilience

Refractory-metal powder is not only expensive feedstock. Inhalation and skin exposure, fire or explosion risks for fine powder, and material-specific toxicology require controls. An E-PBF vacuum chamber does not remove exposure during loading, sieving, depowdering, sampling and waste handling. Closed transfer, extraction, cleaning and lot traceability remain necessary.

European manufacturing capacity may reduce dependence for critical components. Resilience is established only when feedstock has approved alternatives, the process transfers to another machine, and backup service, power, data and inspection capacity exist.

Editorial conclusion

The order matters because it starts production and customer evaluation of specific geometries. It does not show that E-PBF parts are entering qualified defence series production. The next credible signals are accepted property data, repeatable builds, a follow-on contract and an explicit release boundary.
