PyroGenesis Signs Initial Order with Global Aerospace Firm for “Coarse Cut” Titanium Metal Powder for 3D Printing

Expands into Coarse Cut Metal Powder Market alongside Fine Powder

MONTREAL, Sept. 19, 2023 (GLOBE NEWSWIRE) -- PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a TSX30 and a Deloitte Canada Clean Technology Fast 50™ company (the “Company” or “PyroGenesis”) that designs, develops, manufactures and commercializes advanced plasma processes, high quality plasma atomized metal powder for 3D printing, and sustainable solutions which are geared to reduce greenhouse gases (GHG), is pleased to announce that the Company has received a small signed order from a global aerospace firm (the “Client”). This order pertains to PyroGenesis’ plasma atomized titanium metal powders designed for 3D printing and is intended for one of the Client’s ongoing internal research and development programs. Unlike the recently announced contract for fine powder, this new order is for “coarse cut” metal powder, typically considered a by-product from the production runs that produce fine powders ranging from 20-45 µm (microns) in size.

The Client is the large global aerospace original equipment manufacturer (OEM) in the United States with whom the Company has previously disclosed our ongoing qualification process. The order was produced using the Company’s NexGen™ plasma atomization system and will soon be in transit to the Client.

“The significance of this order is the particle size distribution (PSD) that has been requested”, said Mr. P. Peter Pascali, CEO and President of PyroGenesis. “The PSD for this order is for our coarse cut titanium powder, in this case for powder between 45-150µm (microns), which we have been producing over the past year as we build our stock inventory. This contract recognizes what we believe is the superior overall quality of our powder and establishes a market for a larger percentage of our powder output, thereby improving our overall returns substantially.”

“With some traditional metal powder production processes, as the powder is created then filtered and separated into different cut sizes, the fine cut powder is removed for sale, with the remaining coarsest cut often considered of limited use, or even discarded as unsuitable,” said Mr. Massimo Dattilo, VP PyroGenesis Additive. “However, with PyroGenesis Additive’s NexGen™ plasma atomization system, the coarsest cut component of the production batch remains of such a high quality, that we store these powders as inventory for future sales. By selling both the fine and coarse cut of each powder production run, the Company’s yield percentage from raw material is greatly enhanced, which is in line with the Company’s broader mandate for commodity security and optimization.”

“Over the past several years, we designed, then readied, our new NexGen™ plasma atomization process with a goal to produce the highest quality metal powders in the additive manufacturing industry,” added Mr. Pascali. “PyroGenesis Additive has taken a cautious, methodical approach to its new production process. Now, with the full-scale commercialization underway, and a steady influx of initial orders, the long-term conservative strategy that has brought us to this point today is bearing fruit.”

The Company’s development of high quality titanium metal powders is part of the Company’s three-tiered solution ecosystem that aligns with economic drivers that are key to global heavy industry. Metal powders is part of the Company’s Commodity Security & Optimization tier, where the recovery of viable metals, and the optimization of production to increase output, helps to maximize raw materials and improve the availability of critical minerals. Titanium has been identified as a critical mineral by the Canadian government.
