Description
Additive manufacturing (AM) has emerged as a powerful processing route for a wide range of materials. However, for refractory metals (RM), especially for Mo, W and their alloys, its implementation remains particularly challenging because of their unique combination of properties. Very high melting points, low-temperature brittleness, strong sensitivity to impurities, and high thermal conductivity combined with AM-technology specific features, such as a high cooling rate above 106 K/s for laser beam-based methods or deformation during sintering for sinter-based AM techniques, require extensive research to make AM of RM work.
This plenary contribution presents an overview of recent developments, key challenges, and industrial perspectives in the field. Processing routes, including beam-based technologies such as Powder Bed Fusion – Laser Beam (PBF-LB/M) and electron beam methods, as well as indirect approaches based on shaping and sintering, are compared regarding processability, material response, and achievable properties.
The talk concludes by highlighting emerging applications, current technological trends, and future opportunities, with particular emphasis on the potential of AM to enable novel component architectures and to support more sustainable high-performance materials engineering.
