PyroGenesis launches 3D printer materials spinoff for metal powders

Canadian plasma specialist PyroGenesis (OTCQB: PYRNF) has announced a new 3D printer materials division under the name PyroGenesis Additive. First proposed in 2016, the launch has been timed strategically after assessing the market, and receiving significant interest in the company’s specific method of metal powder production.

From the inventors of the plasma atomization process

PyroGenesis’ materials for metal additive manufacturing are produced using the company’s proprietary plasma atomization process, patented in 2015. The process works by firing a metal alloy through heated jets of plasma (energized gas molecules) which turns it into spherical particles.

Powders produced in this way are suited to metal powder bed fusion techniques of 3D printing, i.e.直接金属激光烧结/selective laser melting andelectron beam melting.

The competition

Up until 2012, materials producer AP&C, acquired by GEas part of its $1.4 billion takeover of Arcam and Concept Laser, was in an agreement with PyroGenesis allowing both companies to use the same plasma process. Addressing this competition, P. Peter Pascali, President and CEO of PyroGenesis, says,

GE’s acquisition of Arcam, and by extension of AP&C, has effectively disrupted the supply chain of speciality powders in the AM Industry which has caused end users of such powders to re-examine their access to them, all while PyroGenesis is re-entering the market as a supplier of such powders.

在某种程度上,这是为什么公司等部件l now to launch the additive branch. Pascali also stipulates that,

We have definitely underestimated the interest in our production and it has become apparent that we need to expand our capacity faster than originally planned. We currently have plans to order the long lead items for 3 more systems in anticipation of having to address this need.

Progress faster than expected

PyroGenesis’first successful powder runwas completed March 2017. Since then, the company have receiveda second order for titanium alloy powderfrom a client based in the United States. Pascali also intimates that the company has applied the plasma atomization process to aerospace-grade superalloy Inconel, as usedin research for NASAandSPbPU和TU代尔夫特之间的协作.

Adapting the process for the new material, Pascali comments,

…the powder production rate was far greater than that for Titanium and the Inconel powder was of exceptional quality; proving, amongst other things, the flexibility of our Plasma Atomization System and how quickly we can “pivot”.

“Making great strides”

根据发布,该公司还宣布扩展其ISO 9001:2008质量控制认证,以纳入更具添加剂制造的特定协议。

Closing the announcement, Pascali states,

…our goal is not only to become a significant producer of metal powders to the AM Industry, but to bring the technology to a new level and enable 3D printing to reach new heights by effectively making our old technology, the gold standard, obsolete. We are making great strides on both fronts, and we have only been up and running for less than 3 months.
