Freemelt has received an order for a Freemelt ONE machine from the University of Sheffield targeting material research and development of manufacturing methods for tungsten 3D printed components to be used in fusion energy power plants. The University of Sheffield is one of the world's leading institutes within E-PBF 3D printing technology (Electron Beam Powder Bed Fusion) using a wide range of equipment, optimized for the development of new alloys. Tungsten as a material has high mechanical strength, high corrosion resistance, and the highest melting point of all elements, which makes it suitable for use in industrial processes involving extreme temperatures, such as fusion energy production.

However, due to its extreme melting temperature, tungsten is difficult to manufacture with traditional methods which makes 3D printing particularly attractive for tungsten fabrication.
