• Researchers atConcordia Universityhave introduced a refined 3D printing strategy that uses acoustic energy to fabricate microscopic features directly onto soft polymers such as silicone. • The method, known as proximal sound printing, enhances spatial accuracy compared with earlier sound-based approaches and expands the manufacturing toolkit for delicate materials. • The technique represents a major step forward for microscale manufacturing, enabling highly detailed printing of soft, flexible materials that were previously challenging to shape. • By harnessing focused ultrasound, researchers can create complex microfluidic networks, stretchable sensors, and soft robotic parts with greater accuracy, reduced energy consumption, and improved consistency. • This capability paves the way for faster development of medical diagnostics, wearable technologies, and other advanced microscale devices. • The study was supported by a Discovery Grant from theNatural Sciences and Engineering Research Council of Canada.
