Significant Advancement in 3D Printing Achieved by Concordia Researchers

Researchers at Concordia University, led by Muthukumaran Packirisamy, have achieved a significant breakthrough in 3D printing. They have developed a novel technique called direct-sound printing that utilizes ultrasound waves instead of light and heat to create objects.

Direct-sound printing takes advantage of the energy generated by a process called cavitation. When a substance is stimulated by external force, such as heat, light, or in this case, sound waves, small bubbles form. Similar to how resin is used to preserve plants or insects, direct-sound printing can now be performed using sound waves, allowing objects to be printed in hard-to-reach spaces like the interior of an airplane or within the human body. The process is fast, efficient, and eliminates the need for pouring resin and sealing objects afterward.

One of the most significant implications of direct-sound printing is its potential application in the medical field. While current 3D printing methods are mainly used for creating models or medical devices for educational purposes, direct-sound printing opens up possibilities for inserting medical devices into the body without invasive procedures. This breakthrough could revolutionize medical treatments, allowing for non-invasive placement of devices and improving patient outcomes.
