PyroGenesis Additive Confirms Production, and Orders, for Both Ti-6Al-4V Grade 23 & Grade 5 MIM Cut

MONTREAL, QUEBEC--(Marketwired - Sept. 18, 2017) - PyroGenesis Additive, a division of PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX VENTURE:PYR)(OTCQB:PYRNF), a high-tech company (the "Company" or "PyroGenesis") that designs, develops, manufactures and commercializes plasma waste-to-energy systems and plasma torch products, is pleased to announce today that, further to its press release dated August 14, 2017, wherein it was announced that the Company had developed a new plasma-based atomization process to produce metal powders for 3D printers, specifically the MIM cut titanium (Ti-6Al-4V) powder Grade 5 (which for the purposes herein, we define as small fine metal powders, that can be used by metal 3D printers, typically in the 5um-25um size range), and wherein it was also announced that it seemed that the same process might make titanium MIM cut Grade 23, the Company now confirms that this process can, in fact, make titanium MIM cut Grade 23 powder in commercial quantities. Further to this, the Company is also pleased to announce that it has already received orders for samples of both Grade 5 and, most notably, Grade 23 Ti-6AL-4V MIM cut powders.

Mr. P. Peter Pascali, President and CEO of PyroGenesis, provides an overview of today's announcement in the following Q&A format:

Q. What is the attraction of MIM cut powders?

A. The use of a MIM cut powder allows improved surface finish and increased definition of the parts. MIM cut refers to a powder size traditionally intended for use in the Metal Injection Molding industry, hence the phrase "MIM". We also use this term to describe this same size cut (i.e., the finest powder size produced by plasma atomization, typically below 25um), and which we are seeing a potentially explosive demand for by metal 3D printers. The press has most recently noted the increased interest in using this fine powder by 3D printer manufactures such as Desktop Metal, Markforged and 3DEO. These new printing technologies hold the promise of much higher throughput and reduced costs compared to mainstream printers.

Of note, and where PyroGenesis Additive has applicability, is that the metal 3D printer demands for this MIM cut cannot be serviced by the powders which traditionally were used by Metal Injection Molding, as they are not pure enough.

The MIM cut powder of Ti-6Al-4V has traditionally only been available, in commercial quantities, as Grade 5. Given PyroGenesis Additive's new plasma-based process, as described in its September 12, 2017 news release, it is now able to address this market by producing extremely narrow size distributions, at significantly higher production rates, with higher yields (i.e. little to no waste), and at much lower operating costs for both Grade 5 and Grade 23 in commercial quantities.

To the best of our knowledge, we know of no other company that offers commercial quantities of Ti-6Al-4V Grade 23 MIM cut.

Once again, PyroGenesis Additive is inventing, and innovating, thereby enabling 3D printers to reach new levels.

Q. What is the difference between Grade 5 and Grade 23?

A. The primary difference between the two is oxygen content, with Grade 23 having less oxygen content than Grade 5 (i.e. maximum oxygen content of 0.13% vs 0.20%). Since MIM cut powders are smaller, there is a tendency to have increased oxygen content due to more exposed surface area.¹ Therefore, it is very difficult, in this particle range to have low oxygen content which is sometimes preferred.

Q. Why is it a challenge to make Grade 23?

A. There are two challenges in making Grade 23 MIM cut powder: 1) quality and 2) quantity.

First, quality: because of its small size and relatively high surface area, the powder tends to pick up oxygen easily. By carefully controlling the operating environment of the plasma reactor, it is possible to minimize the oxygen pickup and, consequently, the oxygen content of the final powder.

Second, quantity: plasma processes have traditionally been designed to produce relatively large powders. By allowing to shift the particle size distribution to smaller sizes, the new PyroGenesis process maximizes the amount of powder available in the MIM cut range.

Q. Can you give us an update on sample orders and shipments?

A. To date, PyroGenesis Additive has received six (6) unique sample orders, including one sample order for our Grade 23 and Grade 5 MIM cut. Of these sample orders, we have currently shipped four (4).

Q. So, in conclusion, when will this success translate into more substantial orders?

A. It is important to put these sample orders in context. We never expected to receive any sample orders during the ramp-up phase. It is, as you can imagine, very difficult to project any sales from these sample orders. However, I think it is safe to say that given the amount of interest, the timing, and the type of clients we are seeing, we can expect that some future long-term contracts might be in the very near future. If that is true, one can well imagine that the impact on the Company could be so significant that whether that happens in a week, a month, or six (6) months, the difference in timing is a drop in the bucket when compared to the commercial implications.

I can say however, that these sample orders have translated into company visits; both to our facilities and to theirs… and remember this is all during ramp-up.

As previously announced, PyroGenesis Additive will be exhibiting at this year's TCT show in Birmingham, England (Sept 26 - 28). The TCT Show is one of the world's leading events dedicated to 3D printing, Additive Manufacturing and product development as over 250 exhibitors are showcased to more than 7,000 attendees. We invite those who will be attending the show to stop by our booth# C61 and speak with our sales team: Mr. Massimo Dattilo, VP, PyroGenesis Additive, and Mr. Alex Pascali, Sales Manager, PyroGenesis Additive.

Separately, PyroGenesis announces today that it will be presenting at The MicroCap Conference on October 5, 2017, at the Essex House in New York City. The MicroCap Conference is an exclusive event for investors who specialize in small and microcap stocks. Mr. Pascali will provide an overview of the Company's business, during a live presentation and has scheduled several one-on-one meetings with investors who are registered to attend the conference. This event is exclusive to portfolio managers, analysts, and private investors.
