Harvard Researchers develop method for 3D printing with soundswaves

Researchers from Harvard University’s John A Paulsen School of Engineering and Applied Sciences (SEAS) in Massachusetts, have created an acoustophoretic 3D printing technique which uses sound waves to form drops of a wide range of viscous fluids into additively manufactured structures.

According to the study published in the latest edition of Science Advances, this new patterning method “will drive scientific advances in the areas of optics, electronics, biology, and beyond.”

“Our goal was to take viscosity out of the picture by developing a printing system that is independent from the material properties of the fluid,” said Daniele Foresti, First Author of the paper, the Branco Weiss Fellow, and Research Associate in Materials Science and Mechanical Engineering at SEAS and the Wyss Institute.
