3D printing enables one to rapidly design and fabricate materials in arbitrary shapes on demand. I will introduce the fundamental principles that underpin additive manufacturing. I will then describe how new functional and structural materials are vastly expanding the capabilities of 3D printing. Finally, I will highlight several examples from our recent work, which focuses on printing architected matter.
Jennifer A. Lewis is the Hansjörg Wyss Professor of Biologically Inspired Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences. She is also a Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard.
She earned a Sc.D. in Ceramic Science from the Massachusetts Institute of Technology. She has received numerous distinctions, including the NSF Presidential Faculty Fellow Award, the Brunauer Award from the American Ceramic Society, the Langmuir Lecture Award from the American Chemical Society and the Materials Research Society Medal. She is a Fellow of the American Ceramic Society, the American Physical Society, the Materials Research Society, and the American Academy of Arts and Sciences. She serves on the Editorial Advisory Boards of Advanced Functional Materials and Soft Matter. She has authored 120 papers and holds eight patents.
Jennifer has made pioneering contributions to the directed assembly of soft functional materials. Her work integrates materials synthesis, complex fluids, microfluidics, and robotic assembly to design and pattern functional materials with controlled composition and architecture on multiple length scales (~100 nm - 1 mm). These novel materials may find potential application as printed electronics, waveguides, and 3D scaffolds and microvascular architectures for cell culture and tissue engineering.
To date, Jennifer and her team have developed new classes of concentrated colloidal, fugitive organic, polymer, hydrogel, and sol-gel inks for pen-on-paper, inkjet, roll-to-roll and 3D printing. To expedite the transformation of 3D printing from a prototyping to a manufacturing platform, her team has recently demonstrated high throughput printing of multiple materials via multinozzle arrays. Given the broad applications of this research, Jennifer's work crosses into many areas of translational research, including Adaptive Material Technologies, Bioinspired Robotics, Biomimetic Microsystems, Anticipatory Medical & Cellular Devices and Programmable Nanomaterials.
Additionally, she has been actively engaged in Science, Technology, Engineering, and Mathematics (STEM) education and outreach for nearly two decades.
