Soundwaves are carrying material. And that thing is not a very big surprise because sound waves are the movement of molecules. The thing is that there are also sound waves in the space. Objects like stars are sending material or gas impulses. And that means that molecular movement can observe by using radars. And turn to the sound waves. The gas or other particles can inject into the outer layer of the space structures. But the soundwaves can use in fundamental 3D printing technologies. But the fact is that the coherent sound waves can use in the new fundamental 3D printing tools. In that case, the plastic dust or small plastic particles can carry to a certain position by using coherent sound waves. That thing allows using the modified LRAD-systems for sending particles in long distances. In that kind of 3D printing system, the particles are riding with soundwave or soundwave-laser ray combination. And that thing means that kind of system can be the next-generati...
For finding solutions for problems, we must not claim that some proposition is right or wrong. All possibilities are open. Until they are proven right or wrong using empiric methods that are scientifically accepted.
