How They Destroyed Tartaria 3

Video Transcript:

A new device called Levy Print uses sound waves to levitate and manipulate objects for touch-free building. We spoke to one of the researchers behind Levy Print to learn more about how it works, what it's capable of, and how it could be put to use. Let's check it out. Levy Print is a system that can levitate, manipulate different objects to assemble complex pieces. Of course, these objects could be small spheres, but also droplets of glue and cure it whenever we want, with ultraviolet. And the most important thing and the most novel things that we can levitate, move and rotate sticks. The levitation is created by sound waves that have a frequency approximately double the highest frequency that we humans can hear. When you create these sound fields, they have different shape. They usually have like a wavy pattern. And when you put small objects, they get trapped in this standard wave. In Levy Print's video, you can see the interference patterns created by the sound waves. Dark areas like black, it's like a low amplitude, or if we talk about some low volume, areas that are brighter, that's high intensity. And you can see that the particles they tend to go to the low amplitude areas. These low amplitude areas are good for trapping and manipulating objects like spheres or glue droplets, but when elongated objects like sticks get involved, it gets more complicated. When you levitate small particles or a droplet of glue, it looks like a pair of fingers. It holds the particle there. But when we levitate sticks, we test the different methods. And some fields they look like two pairs of fingers. Others look like if you were holding a sandwich, but they want to work the best, while having two traps at the sides of the stick. Not exactly at the size, but with an offset of 1 millimeter or something like that. The video released by Levy Print shows the device using sticks, spheres, and UV curable glue droplets to build a variety of different shapes, structures, and this orange cat thing. But why might someone want to build using acoustic levitation rather than say another method? There are mainly three advantages of using acoustic levitation to assemble objects. A robot twister could hold something, but then if it's going to hold another material, another part, maybe you need to change the twister, otherwise you will cross-contaminate the pieces. So, acoustic levitation is cool because it minimizes cross-contamination. Another advantage is that with the same levitate or with the same L defector, you can manipulate a variety of things. You can manipulate sticks. You can manipulate particles. You can manipulate glue. And you don't need to swap the holder. And the third one is you can move these parts through holes and cavities. Acier tells me that this Levy Print technology could be useful in the biomedical field, whether worried about cross-contamination or in manufacturing things like watches or phone cameras due to their small and sensitive parts. But it'll probably be a while before we see anything like Levy Print being used commercially. Maybe for Calle Meta 3D printer, it would need to be a more developed prototype. Like there is a process. A system that we give to somebody and they know how to put their 3D model, there will be a software that will slice it or calculate or divide it into parts and then plan the levitation of those parts and then the system will assemble this object. So far, we have some working principles for that, some basic pieces to achieve that, but it still would need more software and engineering. This type of acoustic levitation technology is also being used to create holograms that you can touch and hear. I highly recommend Andy's video about that, which you can find right over there. As always, thanks so much for watching. I'm your host Jess Uroh. See you next time.
