Microvascular multinozzle arrays are designed and fabricated for high-throughput printing of functional materials. Ink-flow uniformity within these multigeneration, bifurcating microchannel arrays is characterized by computer modeling and microscopic particle image velocimetry (micro-PIV) measurements. Both single and dual multinozzle printheads are produced to enable rapid printing of multilayered periodic structures over large areas (≈1 m(2)).

Jennifer A. Lewis and co‐workers report the design and fabrication of microvascular multinozzle arrays composed of multi‐generation, bifurcating microchannels embedded in plastic. Both single and dual multinozzle printheads are produced, which enable rapid printing of functional materials in multilayered structures over large areas (1 m2).
