example

[0427]In an exemplary embodiment, copper can be printed on low glass transition temperature plastics such as polyethylene terephthalate and polycarbonate. The print head that can be used in this exemplary embodiment comprises a fluid delivery assembly and a plasma manifold.

[0428]The fluid delivery assembly comprises a cartridge. In this exemplary embodiment, the cartridge comprises an atomizer, an ink reservoir with a volume of about 2544 mm3; a liquid inlet; a liquid outlet; a gas inlet; a lip with a length of about 4 mm; and a spacer. a dielectric spacer 507 with a length of about 70 mm, an inner diameter of about 10 mm and an outer diameter of about 13 mm; and a lip 506 with a length of about 4 mm.

[0429]To print, a gas is introduced into the fluid delivery assembly through the gas inlet at a gas flow rate of about 600 sccm.

[0430]The operating frequency of the atomizer is about 116 KHz and the atomization rate set at about 40% of the maximum allowed atomization at this frequency. ...
