  • Metal powder for 3D printers and preparation method for metal powder
    Patent number: 10065240
    Abstract: The invention discloses metal powder for a 3D printer. The metal powder for 3D printers is 10-50-micron metal powder made by agglomerating many submicron order metal particles through a granulating process. As the metal powder is combined by submicron order metal particles, the metal powder is low in melting point and high in melting speed, so that the printing speed of the metal 3D printer can be increased and the precision of a printing member can be improved. Meanwhile, the average grain size of the metal powder is equivalent to existing atomized metal powder for 3D printers, and the metal powder has good dispersibility and conveying property, and can be suitable for existing 3D printer equipment.

  • Method and transferred arc plasma system for production of fine and ultrafine powders
    Patent number: 6379419
    Abstract: The present invention is concerned with a method for the production of fine and ultrafine powders of various materials such as metals, alloys, ceramics, composites etc., through a transferred arc plasma system. The method comprises vaporizing or decomposing the material in the plasma reactor, condensing the vapor in a quench tube comprising two sections, the first one for indirectly cooling or heating the vapor, and the second one for directly cooling the vapor. The powder is recovered in a conventional collection unit. The two step condensation in the quench tube allows a substantial control of powder properties like crystallinity, size distribution and mean particle size.
