Inspired by: Grass cell structures

3D Printed Foam Ink

Harvard SEAS (School of Engineering and Applied Sciences) & Wyss Institute

The Problem

Materials used in aerospace and structural applications often sacrifice strength for lightness or vice versa. Manufacturing complex lightweight structures at scale is expensive and material-intensive.

A 3D printable foam ink developed by Harvard SEAS and Wyss Institute inspired by grass cell structures for lightweight, strong materials.

Researchers at Harvard's School of Engineering and Applied Sciences (SEAS) and Wyss Institute developed a 3D printable foam ink inspired by the cellular structure of grass. Grass blades combine strength with lightness through clever cellular organization - they maintain structural integrity while being lightweight and flexible. By mimicking this cellular architecture in a printable foam material, the team created a substance that can be 3D printed into complex shapes while maintaining excellent strength-to-weight ratios. The material has applications in aerospace, automotive, and structural engineering.
