Method for droplet stream manufacturing

In a method of manufacture of a net form product, the improvement comprising the steps of:

• directing a plurality of parallel streams of liquid from a source through a plurality of nozzles onto a collector of the shape of the desired product;
• applying a time variable disturbance internally to the streams upstream of the nozzle exits to produce a spatial breakup of the liquid streams into droplet streams;
• and
• changing the position of nozzles relative to the collector while directing the droplet streams onto the collector.

In a method of manufacture of a net form product in a chamber, the improvement comprising the steps of:

• directing first and second streams of liquid from sources through nozzles toward a collector of the shape of the desired product;
• applying a time variable disturbance to each of the streams upstream of the nozzle exit to produce a spatial breakup of the liquid stream into first and second droplet streams which impact and solidify in a unitary shape on the collector;
• maintaining a vacuum in the chamber;
• and
• directing the first and second droplet streams into collision with each other in the chamber to form disks of the liquid material impacting on the collector.
