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
金属添加剂制造的材料是使用该公司专有等离子体雾化工艺生产的，该过程雷电竞充值于2015年获得专利。该过程通过通过加热的血浆（通电气体分子）发射金属合金来工作，从而将其变成球形颗粒。
以这种方式生产的粉末适合3D打印的金属粉末床融合技术，即直接金属激光烧结/选择性激光熔化和electron beam melting.
比赛
Up until 2012, materials producer AP&C, acquired by GE作为其14亿美元收购ARCAM和概念激光的一部分，与热有关，使两家公司都可以使用相同的等离子体过程。在这场比赛中，Pyrogenesis的总裁兼首席执行官P. Peter Pascali说，
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.
This, in part, is why the company have waited until 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.
进步比预期快
PyroGenesis’首次成功的粉末运行was 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 NASA和SPbPU和TU代尔夫特之间的协作.
Pascali评论，适应新材料的过程，
…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”
In line with the launch, the company has also announced the expansion of its ISO 9001:2008 quality control certification to incorporate more additive manufacturing specific protocols.
Closing the announcement, Pascali states,
…我们的目标不仅是成为AM行业的重要金属粉末生产商，而且还将该技术提升到新的水平，并通过有效地使我们的旧技术（金标准）过时，使3D打印能够达到新的高度。我们在这两个方面都取得了长足的进步，而且我们只启动不到3个月。
