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).
