This article is from 2019 and I probably posted it previously but it is good to revisit based on today's PR.  Here is the quote relating to Pyro...

The second challenge lies in the high cost of titanium powders. For example, the cost of titanium powder optimised for 3D printing ranges from $300 to $600.
 
To reduce the actual material cost per kilogram of titanium, some powder producers have developed alternative powder production methods. Canadian PyroGenesis, for example, is using its NexGen™ Plasma Atomization System, which produces metal powder, including titanium, at over 25 kg/h. Higher production rates allow the company to produce titanium at competitively lower price points.
