Ultra high-frequency sound transmits energy through flesh and other materials that block light or heat used in conventional 3D printing. Concordia University researchers have found a way to use sound ...

A flying machine weighing less than a grain of sand has lifted off without carrying a conventional motor, gears, or onboard ...

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 ...

Engineers at Duke University and Harvard Medical School have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because it responds ...

Researchers at Concordia University have devised a way to solidify liquid into plastic, creating a 3D-printing option that could be used to implement medical implants directly inside a patient's body.

A specially shaped 3D-printed resonator can make air shoot out of its nozzle and provide thrust when it hit with the proper ...

The idea of growing organs or tissues for medical use still sounds like science fiction — and indeed, it's an incredibly difficult thing to do. 3D-printing technology has shown some promise in the ...

Scientists have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological ...
