摘要:
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.
