Contactless Building Construction Could Happen With This New Levitation Device

In a world where 3D printing is being applied to everything from houses to rockets to guns, the question comes up as to where manufacturing might be headed next.

A new device, called LeviPrint, adds a unique feature to the manufacturing process: acoustic levitation. By trapping small objects in high frequency sound waves, LeviPrint can be used to build a variety of different structures without touching any of the pieces.

In a video released by researchers from Spain’s Universidad Publica de Navarra, or UPNA, LeviPrint can be seen building a variety of different things, including a bridge, a hoop made out of liquid glue droplets and a cat’s ears.

Asier Marzo, a researcher from UPNA, told CNET that he envisions LeviPrint’s touch-free technology could someday prove useful in the biomedical field, where cross-contamination could be an issue, or in manufacturing watches and phone cameras, because of their small and easily damaged parts.

He also mentioned that its acoustic levitation could be useful in future 3D printers, but more hardware and software engineering would be necessary before LeviPrint could be considered a member of the 3D-printer category.
