And this regarding their powders....very encouraging...may have a monster in the making here

"PyroGenesis is the inventor of Plasma Atomization - a plasma-based process that produces small, spherical, metal powders for the Additive Manufacturing ("AM") industry, particularly 3D printing, and which has become the gold standard.

The Corporation recently announced the successful completion of the ramp-up of its first (1st) plasma atomization system since announcing, in 2015, that it would become a supplier of powders to the AM industry. During ramp-up, the Corporation not only received several sample purchase orders, but also developed new Intellectual Property which effectively allows the manufacture of very narrow particle size distributions, at higher production rates, with little-to-no waste. The Corporation feels that this breakthrough could be even more game changing than its original Plasma Atomization patent."
