UpnaLab scientists developed LeviPrint, a system for assembling objects in a contactless manner using acoustic levitation. They explored a set of optimum acoustic fields that enables full trapping in position and orientation of elongated objects such as sticks. They then evaluated the capabilities of different ultrasonic levitators to dynamically manipulate these elongated objects.
The combination of novel optimization algorithms and levitators enable the manipulation of sticks, beads and droplets to fabricate complex objects. A system prototype composed of a robot arm and a levitator is tested for different fabrication processes.
UpnaLab highlights the reduction of cross-contamination and the capability of building on top of objects from different angles as well as inside closed spaces. They hope that this technique inspires novel fabrication techniques and that reaches fields such as microfabrication of electromechanical components or even in-vivo additive manufacturing.
