Defying Gravity: LeviPrint Uses Sound Waves to Levitate Objects

A new device called LeviPrint uses high-frequency sound waves to levitate objects and build various structures.

#Levitation #WTF

when i was in college, this was experimental by other students to just shove a lot of ultra sonic sensor to levitate beads, but the resolution was super low and the beads would vibrate, now 8 years later and someone figured out they can use use an arm to precisely move the beads instead!

This is how the pyramids were made, apparently

I doubt even the creators/researchers fully grasp the potential of this technology.
It is quite literally revolutionary.

Imagine this tech combined with a laser sintering metal 3D printer. I thought of that awhile, using Sonic levitation... Looks like it's even more viable then I believed.

[iblackfeathers]

once this becomes more well known, someone is going to incorporate this acoustic levitation into a movie.

Something like this leviprint would be usefull for reduction of waste print materials. Use this in conjunction with a 3D printer to hold up objects so there is no or less need for support structures during 3D printing. Would work for both melting and liquid image methods. An example is 3D printing a pyramid upside-down or a cube with the corners facing the top and bottom.

Use this technology to levitate millions of sand-sized LED. You now have an efficient, working 3D hologram that people can walk through and interact with. Thank me later :D

The rotation aspect is something I am surprised 3D printers dont use shifting the gravity for stuff like overhangs. If you rotate the entire machine so the overhang is vertical, the lines would be flat. Of course the slicer would need a 4th axis output for gode or some sort of post processor. With a 5th axis supports all together may be eliminated depending on how quickly you move/cooling. I am not talking about rotating the nozzle angle which has been done. I am talking about rotating gravity to rest the lines on material that has already been extruded.

I remember this technology from a few years ago but it seems like it's becoming more sophisticated, they couldn't do sticks only small pellets.

About time anti-gravity was advanced! 🤩

[realtalkphph]

this could be the start that human can levitate in the future. oh men, what we seen in futuristic movies is slowly coming through, like robots, flying cars, etc.

I hope they can create a machine sound wave to levitate or at least push an asteroid away from earth ASAP.

[seantotherose]

I can't wait to see where this goes in the next 10 years

Here's a theory ufo uses sound waves externally to float around that's why you don't hear sound of an engine and using sound waves pushes their craft to go faster

[GraniteInTheFace]

I'm more interested if we can increase the efficiency and output of the high frequency emitters so we can start making force shields. And afterwards? Hover boards.

[ScottJPowers]

one step closer to star trek replicators. this thing could one day rapidly assemble small particles of materials and glue, or particles of food material cooked with laser pulses, to make the item or food you want appear outta thin air.

[jhendies]

So you took a highschool science project and attached it to a robotic arm.... 😂

[johnwang]

Keep in mind that acoustic levitation works best with small light objects such as the aerosols that distribute COVID. It's quite possible to have arrays of ultrasound transducers sweeping aerosols to the ground or to the intakes of HEPA filters or even to produce ultrasonic force fields around people. Whether or not it would be a good business model to research, develop and market such devices is another matter.

[SUPPASKA]

A similar method to do this is with lasers. Search for "optical tweezers". It was the topic of a recent Nobel Prize

[avnger]

Levitation packs using magnetism and Soundwaves, vehicles that float by having magnetic plates instead of wheels that have changing magnetic polarity at the molecular level depending on the surfaces beneath it is also another idea. Using sound waves for sonic weaponry to disrupt wireless communication signals. Creating armor that allows the user to power slide using reverse magnetism. Those ideas are all in my book

[manicmarauder]

Now combine the sound waves with darpa's plasma shielding for vehicles (basically superheated air to stop incoming rounds) and use those to create as needed 'mirrors' to reflect the sound and you can do away with needing the big emitters on both sides ... though you might introduce a heat issue. Man what we'll be able to do in the future will look like absolute magic even to people today if we don't blow ourselves up and regress.
