Freemelt has received a project contract from Oxford Sigma to conduct geometry tests on additively manufactured tungsten components. The study aims to validate the feasibility of producing critical parts for fusion energy applications. This contract underscores Freemelt’s growing role in the energy sector and follows its ongoing projects in additive manufacturing of tungsten. The project is scheduled for implementation in Q1 2025.
Freemelt will utilize its proprietary Electron Beam Powder Bed Fusion (E-PBF) technology and its industrial eMELT machine for this initiative. This process enables the fabrication of high-strength, heat-resistant tungsten components, designed to withstand extreme thermal conditions. If the material proves suitable, Oxford Sigma plans to further refine component designs and conduct tests under real-world operating conditions.
“This order further confirms our strong position in the energy sector and our expertise in manufacturing critical components in tungsten, which is one of the most challenging materials to process, but offers exceptional strength and durability at extreme temperatures,” says Daniel Gidlund, CEO of Freemelt.
Oxford Sigma is a technology company specializing in materials science and design solutions for fusion energy. In early 2025, the company formed a strategic partnership with Swedish firm Novatron to develop new designs for future fusion power plants. The ongoing project with Freemelt could mark a significant step toward the commercialization of fusion energy and further advancements in material research for nuclear applications.
