It was PyroGenesis' 3D Powders/Additive Manufacturing division that brought me to PyroGenesis in the summer of 2017. I have been a shareholder ever since (and continue to add to my position).
Boeing used PyroGenesis' 3D printing powders for 2 studies:

The fact that Boeing selected PyroGenesis for these studies further validates PYR's powders (take a look a the results in the studies, PYR's powders are superior).
And PyroGenesis is featured in the Titanium 3D Printing - The Ultimate Guide. Thanks to @cargo for these:

That 3D printed nose landing gear part for Safran (screen shot above) is made from titanium:) https://www.slm-solutions.com/company/news/detail/safran-and-slm-solutions-evaluate-slmr-technology-for-additively-manufactured-main-fitting-of-a-bizjet/ @cargo Here is one on Aluminum- The Ultimate Guide https://all3dp.com/1/3d-printing-aluminum/ Really look forward to hearing more about $PYR aluminum powders in the future:) Long and Strong in PyroGenesis!
