New patent-pending 3D printing method utilizes ultrasound to move individual particles

The noncontact method of 3D printing, developed by NeuroTechnology, utilizes ultrasonic waves to manipulate delicate components. A new method of 3D printing could be utilized to manipulate single cells. Developed by the Ultrasound Research Group at Neurotechnology (Latvia), it utilizes ultrasonic waves to manipulate individual particles with causing any damage, making it useful for biological applications such as bioprinting. In the demonstration above, an array of ultrasonic transducers were utilized to accurately position electronic components on a PCB board. A laser was then utilized for soldering the elements onto the PCB. This method could also be applied to producing 3D...
