  • Method and apparatus for droplet stream manufacturing
    Patent number: 5340090
    Abstract: A method of manufacture of a net form product, including directing a stream of liquid from a nozzle onto a collector of the shape of the desired product, applying an amplitude and time dependent modulated disturbance to the stream to produce a droplet stream, and with the nozzle and collector in a chamber, controlling the chamber environment. An apparatus for manufacturing a net form product having a source of molten material under pressure, a support for positioning a product collector in a chamber with the collector defining a desired product, a droplet stream generator positioned within the chamber and including a nozzle, a conduit for conducting molten material from the material source to the generator nozzle, a mechanism, typically a modulator, for amplitude and time dependent modulation disturbance of the droplet stream, and a drive mechanism for relative movement of the nozzle and support.

  • Apparatus for droplet stream manufacturing
    Patent number: 5259593
    Abstract: A method of manufacture of a net form product, including directing a stream of liquid from a nozzle onto a collector of the shape of the desired product, applying a disturbance to the stream, preferably an amplitude modulated disturbance, to produce a droplet stream, and with the nozzle and collector in a chamber, controlling the chamber environment. An apparatus for manufacturing a net form product having a source of molten material under pressure, a support for positioning a product collector in a chamber with the collector defining a desired product, a droplet stream generator positioned within the chamber and including a nozzle, a conduit for conducting molten material from the material source to the generator nozzle, a mechanism, typically a modulator, for disturbing the droplet stream, and a drive mechanism for relative movement of the nozzle and support.
