New 3D Printing Method Uses Soundwaves to Create Objects

Go Digital

What happened? A new 3D printing method that uses soundwaves to create objects has the potential to be a game-changer in the industry. Researchers say that the technology, called direct sound printing (DSP), may offer a third option besides photo and thermo 3D printing methods. Ultrasonic frequencies are already being used in destructive procedures like laser ablation of tissues and tumors. Now, researchers have harnessed their power to create new objects with DSP.

Why is this important? 3D printing is an important technology with the potential to revolutionize manufacturing. It allows for the creation of objects with customized shapes, which could lead to more efficient production and less waste. DSP 3D printing may offer even more precise control over 3D printed objects, opening up new possibilities for manufacturers.

DSP, in the researchers' words, is created by fluctuating pressure inside tiny bubbles trapped in a liquid polymer solution. They learned that if they utilized a certain sort of ultrasound with a particular frequency and power, they can generate very tiny, chemically reactive zones. The bubbles can be used as reactors to drive chemical reactions to turn liquid resin into solids or semi-solids.

Intense chemical reactions occur inside the tiny bubbles due to ultrasound-wave-powered oscillation. They only last picoseconds, however. The cavity's temperature rises to around 15,000 degrees Celsius and the pressure rises to 1000 bar (the Earth's surface pressure at sea level is about one bar). Because the reaction time is so short, the heat doesn't have time to spread out and damage the surrounding material.

The researchers say that this 3D printing method is compatible with a wide range of materials, including metals, glass, and ceramics. They believe that DSP has the potential to 3D print objects with unprecedented levels of detail and accuracy. The next step is to commercialize the technology so that it can be used in a variety of applications.

Do you think DSP 3D printing will become the new standard? Why or why not? Let us know your thoughts in the comments below!
