Ever since the first known audio recording, there has always been a lot of passion around sound quality with many different companies offering their own approaches to best present audio recordings.

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 ...

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 ...

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 ...

A rapid form of 3D printing that uses sound and light could one day produce copies of human organs made from a person’s own cells, allowing for a range of drug tests. Traditional 3D printers build ...

A schematic of the DISP (deep tissue in vivo sound printing) platform developed by a team led by Caltech. The technique combines ultrasound with low-temperature–sensitive liposomes loaded with ...
