Sound Waves Let Researchers Build Stuff with the Force

A system for assembling elongated objects into large structures without physical contact has been created by researchers at the Public University of Navarre, Spain and the University of São Paulo, Brazil. LeviPrint is a physical acoustic levitator that can produce sound waves to trap and hold objects and put them together when affixed to a robot arm. The levitator also manipulates liquids, glues, or resins, and the device could be useful for building the small components in electronics.

LeviPrint's lifting capabilities are currently constrained to small, lightweight objects, but the system can move and reposition parts behind barriers or within existing structures. LeviPrint's developers envision the technology as a complement to additive manufacturing, or three-dimensional printing.
