High‐Throughput Printing via Microvascular Multinozzle Arrays

Abstract

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)).

3D Bioprinting of Vascularized, Heterogeneous Cell‐Laden Tissue Constructs

“…To fully optimize this approach, we plan to systematically study each of these important parameters in future experiments. By implementing multinozzle printheads, [ 35 ] which we designed previously for high-throughput, multimaterial printing, the characteristic build times would be vastly reduced. For example, it would require 3 days to print an engineered tissue construct with a volume of ca.…”

Mechanisms, Capabilities, and Applications of High‐Resolution Electrohydrodynamic Jet Printing

“…Truly high-throughput e-jet printing will require the development of approaches to fabricate print heads that contain large arrays of nozzles comparable in scale to those used in conventional ink-jet printers or developed for other directwrite systems. [ 89 ] Initial efforts with large-scale nozzles show promise. Conventional microfabrication methods can be used to form multi-nozzle arrays for e-jet printing, as explored by several different research groups.…”

Microvascular-based self-healing materials

“…Risers were similarly drilled between a brittle coating surface to an underlying 3-D printed matrix for fluid access [62]. The broader field of microfluidics has similarly used CNC (computer numeric control) milling to achieve features 100 mm to 1 mm in diameter [63,64] or EDM (electrical discharge machining) to produce features on the order of 10 mm [65,66].…”
