Abstract: A method of producing full density binder-jet printed metallic articles. A metallic 3-D printed article is produced using a binder-jet printing method and is positioned in a hot isostatic press (HIP) container surrounded by stabilization powder. A vacuum is introduced into the inside of the HIP container. A binder used to bond powder articles together in the printed article is removed by heating the HIP container to decompose the binder and removing decomposition products by applying a vacuum to the HIP container. The HIP container is sealed with a vacuum therein and compacted under heat and pressure to remove all porosity in the printed article. The printed article thereafter is removed from the HIP container and finished to a final form.

The intermediate spherical particles include a polycrystalline or single-crystalline region, having a particle size of 1 to 300 μm. The method of the present invention further includes a second step for producing final spherical particles. The second step uses a swirling plasma gas flow having the central axis thereof, the central axis running through an area between an anode and a cathode of a plasma generator. The intermediate spherical particles are discharged along the axis to subject the intermediate spherical particles to a plasma atmosphere of the area to form the final spherical particles.
