  • Powder characteristics and morphology

    Powder for Additive Manufacturing

    Osprey® metal powder for Additive Manufacturing is characterized by a spherical morphology and high packing density, which confer good flow properties. For powder bed processes these are essential when applying fresh powder layers to the bed to ensure uniform and consistent part build.

    For blown powder processes, such as Direct Energy Deposition (DED), good flow ensures uniform build rates. Tight control of the particle size distribution also helps ensure good flowability. Low oxygen powders result in clean microstructures and low inclusion levels in the finished parts.

  • Particle size distribution

    Powder for Additive Manufacturing

    Osprey® metal powder for Additive Manufacturing is available in a wide range of particle size distributions that are tailored to the individual Additive Manufacturing systems. They can also be tailored to the particular requirements of the end application, both in terms of mechanical performance and surface finish.

    Typical particle size distributions for Additive Manufacturing.

    Typical particle size distributions for Additive Manufacturing
    Process technology Size (µm)
    Binder jetting ≤ 16, ≤ 22, ≤ 32, ≤ 38, ≤ 45
    Laser - Powder Bed Fusion (L-PBF) 15 to 53 and 10 to 45
    Electron beam - Powder Bed Fusion (E-PBF) 45 to 106
    Direct Energy Deposition (DED) 53 to 150

    Tailor-made particle size distributions are available on request. Contact us to discuss your specific requirements.
