Abstract
A powder production method includes providing at least one elongated member including a ductile material; providing a rotating or vibrating cutter configured to repeatedly cut an end of the at least one elongated member to produce particles; and advancing the at least one elongated member or the cutter towards the other of the at least one elongated member or the cutter to cut the particles from the at least one elongated member to produce a powder comprising a plurality of the particles. The particles produced by the method can have a diameter ranging from about 10 μm to about 200 μm.
Claims25
A powder production method comprising:
- providing a plurality of elongated members comprising a ductile metal material;
- providing a rotating or vibrating disk configured to repeatedly cut ends of the plurality of elongated members to produce particles, wherein the disk comprises a proximal surface, a distal surface, and a plurality of holes, each of which is configured to receive one of the plurality of elongated members, and wherein longitudinal axes of the plurality of elongated members are transverse to the proximal surface or the distal surface of the rotating or vibrating disk;
- and
- advancing the ends of the plurality of elongated members or the disk towards the other of the ends of the plurality of elongated members or the disk, such that the ends of the plurality of elongated members are inserted through the plurality of holes of the disk in order to cut the particles from the ends of the plurality of elongated members to produce a powder comprising a plurality of the particles having a diameter or maximum dimension ranging from about 10 μm to about 200 μm.
