    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.

    Powder for Metal Injection Moulding (MIM)

    Osprey® MIM powder has a spherical morphology, resulting in high packing density. This enables the manufacture of feedstocks with high powder loading, which not only minimizes binder costs but also reduces part shrinkage during debinding and sintering. Spherical powder also has excellent flow characteristics, resulting in reduced tool wear and consistent mould filling.

    Osprey® MIM powder's low oxygen content allows better control of carbon and consistency during sintering. Low oxygen levels, together with high packing density, also facilitate faster sintering.

  • 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.

  • Microstructure

    Below are microstructure images of Osprey® C18150. The samples were produced by Binder Jetting (-18 µm) on the Desktop Metal Production System™ P-1 where a relative density over 98% was achieved. The sintered microstructures in as-polished and etched condition are shown below where a low level of porosity is seen and overall a homogenous and fine-grained microstructure.Micrograph of Osprey® C18150 in a) as-printed and b) etched conditions.
