AM 4 AM, a producer of metal powders for Additive Manufacturing based in Foetz, Luxembourg, has announced that it has received a Chinese patent for its metal powder plasma treatment. This follows on from the company’s October granting of a patent in the Japanese market.


The company’s cold plasma technology works by evenly coating the surface of metal powders with ceramic particles to produce a dense microstructure that is reported to improve the powder’s durability, processability and reliability. Requiring only 2 kW of power per hour of processing time, the process runs entirely on nitrogen gas, reducing the use of potentially harmful chemicals.


“This is a key step in protecting our technology in one of the most dynamic Additive Manufacturing markets worldwide,” AM 4 AM stated on LinkedIn. “Innovation has no borders, and we’re proud to see our work recognised across continents.”
