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!

Christian is a futurist and trendwatcher who speaks about the impact of exponential technologies like AI on organizations, people, and talents. Christian tailors his presentations to your audience’s specific industries and needs.
Embracing the advancements of technology and AI can enhance our humanity. We can focus on developing our unique talents and skills by automating mundane tasks and freeing up our time. As humans, we can adapt and learn, allowing us to evolve and stay relevant in a rapidly changing world constantly.
Organizations will need to be more fluid, dynamic, and adaptable: the ability to change and adjust in response to new situations and environments. We are on the cusp of a new era of organizations, ones that are more fluid and agile and which behave like swarms we see in nature.
In the future, 3D printing and generative design will allow for products to be designed in a more decentralized manner, and production will take place closer to the customer and fully on-demand. 3D printing technology will also allow for more customization and personalization of products.
The agricultural industry is ripe for disruption. Robotics, AI, and IoT are all technologies that have the potential to radically transform the way we grow food. In combination with vertical farming, these technologies could increase the efficiency and quality of agricultural products.
A human-centered society is one that puts people first and where technology is used to unite and empower people. It is a society that values biological life and dignity above all else. It is a society that recognizes the importance of human relationships and works to strengthen them. In a human-centered society, all members of the community are valued and treated with respect.
The future of healthcare is here. New technologies like AI, IoT, big data, and smart sensors make it possible to become the CEO of your own health. Imagine that your phone can listen to your voice and AI algorithms can detect small nuances in the tone of your voice that indicate specific diseases.Â
