U.S. metal powder manufacturer Continuum Powders has released its Metal Additive Manufacturing Circular Manufacturing Handbook, based on independent testing from Rice University’s Particle Flow and Tribology Lab. The tests show that recycled M247 nickel-based superalloy powder outperforms 2205 and 316 stainless steel powders in additive manufacturing suitability. Using an FT4 powder rheometer to evaluate flow and packing behavior during the powder recoating stage, M247 demonstrated the best performance in adjusted bulk density, compressibility (~2%), stability index, and flow rate index. Continuum Powders employs its Greyhound melt atomization platform, combining cold-wall plasma melting with inert horizontal gas atomization, to convert scrap components, rework materials, and defective prints into specification-grade AM feedstock powder. This case demonstrates a commercially viable 'scrap-to-qualified powder' pathway, which, if more widely validated, could reduce the reliance of high-end metal powders on virgin mineral resources.
