Microfluidic Printheads for Multimaterial 3D Printing of Viscoelastic Inks

James O Hardin et al. Adv Mater. .

Abstract

Multimaterial 3D printing using microfluidic printheads specifically designed for seamless switching between two visco-elastic materials "on-the-fly" during fabrication is demonstrated. This approach opens new avenues for the digital assembly of functional matter with controlled compositional and property gradients at the microscale.

Keywords: 3D printing; ink; microfluidics; multi-material; viscoelastic.
