Multimaterial 3D Printing Helical Filaments

Researchers have developed a rotational multimaterial 3D printing method for creating helical filaments. Using this new approach, the team designed and fabricated artificial muscles and springy lattices for use in soft robotics and structural applications. The new printhead consists of four ink cartridges, each of which can contain different materials. Watch this video to learn more.

“Rotational multimaterial printing allows us to generate functional helical filaments and structural lattices with precisely controlled architecture and, ultimately, performance,” said Natalie Larson , a postdoctoral fellow at SEAS and first author of the study.
