摘要： A method of making a ready-to-print cermet or cemented carbide powder of sintered granules includes the step of sintering the granules in a carburizing atmosphere. Due to the carburizing atmosphere, the granules will have less binder phase on the surface and will not sinter together and will be easy to deagglomerate and the granules will maintain its spherical shape. A powder made according to the method, as well as the use of the powder in an additive manufacturing process is provided.

摘要： Metal powder particles for use in additive manufacturing are made by removing material from the surface of the particles using wet chemical etching to create a nanoscale texturing of the surface, increasing absorptivity by the metal powder particles of incident laser light and maintaining flowability. The nanoscale texturing has sub-wavelength features at laser wavelengths in the range 800-1100 nm. The particles are substantially spherical and have mean diameters in the range 10-70 μm.
