Scientists at Germany’s Chemnitz University of Technology have spent years developing compact and discreet speakers that are quite literally paper thin, and the latest breakthrough improves on this ...

Harvard University researchers have developed a new printing method that uses sound waves to generate droplets from liquids with an unprecedented range of composition and viscosity. This technique ...

Researchers have developed a new printing technology that uses sound waves to control the size of liquid droplets independent of fluid viscosity. This approach could greatly broaden the types of ...

In holographic direct sound printing, a transducer emits high-acoustic pressure sound waves, inducing a sonochemical reaction called cavitation that creates solid material inside the build chamber. A ...

Researchers from Concordia University have created a new platform technology called direct sound printing (DSP), which uses soundwaves to create three-dimensional objects, compared to the current ...

Ultra high-frequency sound transmits energy through flesh and other materials that block light or heat used in conventional 3D printing. Stephen Shankland worked at CNET from 1998 to 2024 and wrote ...

Canadian researchers at Concordia University want to change how you do 3D printing. Instead of using light or thermal mechanisms, they propose using ultrasound-activated sonochemical reactions. Sounds ...

3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by ...

Mechanical engineers Shervin Foroughi and Mohsen Habibi were painstakingly maneuvering a tiny ultrasound wand over a pool of liquid when they first saw an icicle shape emerge and solidify. The pair ...
