3D-Printing of Lightweight Cellular Composites

A new epoxy‐based ink is reported, which enables 3D printing of lightweight cellular composites with controlled alignment of multiscale, high‐aspectratio fiber reinforcement to create hierarchical structures inspired by balsa wood. Young's modulus values up to 10 times higher than existing comm...

Zusammenfassung:A new epoxy‐based ink is reported, which enables 3D printing of lightweight cellular composites with controlled alignment of multiscale, high‐aspectratio fiber reinforcement to create hierarchical structures inspired by balsa wood. Young's modulus values up to 10 times higher than existing commercially available 3D‐printed polymers are attainable, while comparable strength values are maintained.
