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