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 ...

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 ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have ...

When an object is 3D printed, a computer processes an object’s design and sequentially “prints” each of its layers on top of one another. In a new form of 3D printing from the Max Planck Institute for ...

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.

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 ...

Black holes famously trap light. A new acoustic device borrows the idea to swallow sound. (Yukterez/Wikimedia Commons, CC ...
