Loughborough University adopts Freemelt E-PBF technology for advanced materials research. The Department of Materials, led by Professor Moataz Attallah, has integrated Freemelt's Electron Beam Powder Bed Fusion (E-PBF) system to expand capabilities in processing high-temperature and reactive metals. This partnership focuses on overcoming limitations inherent in laser-based systems, specifically targeting the additive manufacturing of copper, tungsten, tantalum, molybdenum, and niobium. The E-PBF process utilizes a high-vacuum environment to prevent oxidation, allowing for the precise thermal management required for these challenging material classes.

This adoption highlights the growing demand for open-architecture E-PBF systems in academic and industrial R&D. While laser-based powder bed fusion (LPBF) dominates the market for standard alloys like Ti-6Al-4V, it often struggles with the high reflectivity and thermal conductivity of materials like copper or the high melting points of refractory metals. By utilizing an electron beam, researchers can maintain higher bed temperatures, reducing residual stress and cracking in brittle or highly conductive components. This move positions Freemelt as a key provider for specialized material development, contrasting with the closed-ecosystem approach of larger incumbent manufacturers.

For researchers and industrial users, this installation validates the utility of open-source E-PBF platforms for metallurgical innovation. The focus must now remain on developing repeatable process parameters for these non-standard materials to bridge the gap between laboratory-scale testing and industrial production. Users should prioritize the characterization of material microstructures to ensure that the vacuum-based E-PBF process delivers the required mechanical properties for high-performance applications.
