A method for multi-material plasma jet printing, comprising:
- (a) providing a plasma module, a cartridge, and a dielectric spacer disposed between the plasma module and the cartridge, wherein the plasma module comprises a dielectric tube, a first electrode, and a second electrode, wherein the dielectric spacer has a length that is greater than a distance between respective centers of the first electrode and the second electrode, and wherein the cartridge comprises an atomizer;
- (b) aerosolizing an ink, using the atomizer, to generate an aerosolized ink;
- (c) flowing the aerosolized ink, through the dielectric spacer, from the cartridge to the plasma module;
- (d) exposing the aerosolized ink to plasma generated by the first and second electrode of the plasma module to generate a plasma-treated aerosolized ink;
- and
- (e) printing the plasma-treated aerosolized ink on a substrate.
