This new 3D printing method uses ultrasonic, non-contact manipulation technology and has the potential to print and then assemble all the components of a smartphone. The ultrasonic 3D printer comes from Lithuanian software development firm Neurotechnology. According to Digital Trends, their assembly device could completely alter the way we currently consider 3D printers by making additive manufacturing more versatile.
The 3D printing method takes the form of an apparatus that "uses an array of ultrasonic transducers that emit ultrasonic waves." The machine can trap and move small particles, meaning it is capable of 'printing' just about anything. So far they have developed a working prototype, so it could be a while before this sort of (patent pending) technology is more widely available.
