Organic Vapor Jet Printing (OVJP) concept schematic

OVJP Concept Schematic

 

Organic Vapor Jet Printing (OVJP) in vacuum and Guard Flow-Organic Vapor Jet Printing (GF-OVJP) in atmosphere.  The guard flow hydrodynamically focuses the jet of the organic vapor that would otherwise have a reduced edge sharpness and patterning resolution due to increased gas density.

Precision fiber networks made by direct jet writing using the biodegradable polymer PLGA from the Lahann Lab.  White scale bars (lower right corners or each image) represent 1 mm (a), 500 um (b, e, d), 100 um (c, g) and 50 um (f, h, i)
