PyroGenesis, a Montreal-based company with experience in advanced plasma processes and products has figured a way out to reduce the manufacturing costs of spherical powder particles for use as metal AM. The European Patent Office has issued its intent to grant the company a patent for the so-called “Plasma Apparatus for the Production of High Quality Powders at High Capacity”, which like all good patent applications titles is fairly descriptive of what it does. In addition, the patent application itself contains a sketch of the system to give you some further idea of how it all works.
