Contactless Building Construction Could Happen With This New Levitation Device

Contactless Building Construction Could Happen With This New Levitation Device

In a world where 3D printing is applied to everything from houses to missiles to gunsthe question arises where the production will go 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.

LeviPrint moves a small sphere with acoustic levitation.


A video released by researchers at Spain’s Universidad Publica de Navarra, or UPNA, shows LeviPrint building several things, including a bridge, a hoop made from liquid glue drops and a cat’s ears.

Asier Marzo, a UPNA researcher, told CNET that he envisions LeviPrint’s touch-free technology could one day be useful in the biomedical sector, where cross-contamination could be a problem, or in the manufacture of watches and phone cameras, due to their small size. and easy damaged parts.

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