PyroGenesis Canada Inc., a renowned high-tech company specializing in advanced plasma processes and sustainable solutions, has recently been granted a US patent (US 11839918) for its NexGen plasma atomization powder. This prestigious patent, titled “Method and Apparatus for Producing High Purity Spherical Metallic Powders at High Production Rates From One or Two Wires,” recognises PyroGenesis’ cutting-edge technology in producing metal powder for additive manufacturing.
The NexGen plasma atomization technology revolutionizes the production process by offering higher and more efficient production rates, as described in the patent. The system’s innovative features include a two-wire simultaneous feedstock approach, where the wires are electrically charged before reaching the plasma atomization step.
Pierre Carabin, PyroGenesis’ Chief Technology Officer and Co-inventor of the technology, highlighted the significant improvements of the NexGen process. Not only does it enable higher production rates, but it also ensures a narrower particle size distribution, providing uniformity and consistency, and the ability to tailor particle size distribution (PSD) to customer requirements.
Traditional plasma atomization has faced challenges due to its relatively low production rate. To address this, PyroGenesis Additive’s NexGen system employs a unique approach, feeding two separate spools of metal wire that are electrically charged. This results in a more efficient atomization of the metal and significantly increases production output.
Massimo Dattilo, Vice President of PyroGenesis Additive, emphasized the company’s dedication to advancing plasma atomization. With the US patent for NexGen serving as a key validation of their innovative approach, PyroGenesis Additive is committed to pushing the boundaries of plasma atomization to drive progress in the industry.
PyroGenesis Canada Inc. takes pride in its strategic and cautious approach in developing and commercializing the NexGen plasma atomization process. After years of research and development, the company has recently achieved full commercialization and entered the titanium metal powders marketplace with its first by-the-ton commercial order.
The company’s development of high-quality titanium metal powders aligns with its Commodity Security and Optimization tier, contributing to the recovery of viable metals and maximizing raw materials. As titanium has been identified as a critical mineral by the Canadian government and other global jurisdictions, PyroGenesis’ innovative approach holds great promise for the future of additive manufacturing industry.
In conclusion, the US patent for NexGen plasma atomization powder marks a significant milestone for PyroGenesis Canada Inc. This achievement underscores the company’s commitment to continuous improvement and innovation, and its dedication to providing high-quality metal powders that meet the needs of the additive manufacturing industry. With a bright future ahead, PyroGenesis Additive’s groundbreaking technology is set to reshape the industry and drive further advancements in plasma atomization.
