NUST MISIS has proposed an ultrasonic atomization-based method for recycling metal additive manufacturing waste. Metal scrap—including support structures, which can account for up to 50% of billet volume in some cases, and defective parts—is melted by an electric arc. The molten metal flows onto a surface vibrating at up to 50,000 times per second, instantly solidifying into spherical powder under argon protection. The recycled powder achieves a sphericity coefficient of 0.90 (where 1 indicates a perfect sphere), surpassing the 0.85 of the original powder, making it directly usable in high-precision 3D printing equipment such as selective laser melting (SLM). Lead author Olga Bashmakova, an engineer at the NUST MISIS Additive Manufacturing Laboratory, stated that higher sphericity results in better rheological properties and packing density during powder spreading. The technology is particularly effective for recycling waste from additive manufacturing of precious metals like platinum, helping to reduce product costs in the medical and aerospace sectors.
