Description
Simona Svozilova and co-authors test recycled metal powders for 3D printing in this 2024 study. The method, called DMLS, builds metal parts layer by layer with a laser. Fresh powder is costly and mining harms the environment, so reuse matters.
The team compared virgin, recycled, and reused powders from MS1 steel in the lab. Recycling was done by melting and gas atomizing the metal. Tests covered grain size, shape, hardness, and flow. Recycled powder had more small grains and a changed grain shape. Its hardness fell by about a third, and it would not flow through test funnels. Reused powder flowed faster than virgin powder.
