A method and apparatus for delivering a mixture of compressed fluid and
marking material and depositing the marking material in a pattern onto a
substrate, includes a high pressure source of a mixture of compressed
fluid and marking material. A micro-machined manifold includes a
plurality of micro-nozzles, a fluid chamber, and an entrance port with
portions of a first surface of the micro-machined manifold defining the
entrance port with the entrance port being connected in fluid
communication with the fluid chamber. Each of the micro-nozzles having an
inlet and an outlet with the inlet being connected in fluid communication
with the fluid chamber and the outlet being located on the second surface
of the micro-machined manifold. Each micro-nozzle is shaped to produce a
directed beam of the mixture of compressed fluid and marking material
beyond the outlet of the micro-nozzle. A housing is connected in fluid
communication with the high pressure source and the entrance port of the
micro-machined manifold with the connection being a sealed connection.
Optionally, a device operable to capture marking material that does not
adhere to the substrate can be included.
