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 ...

Additive manufacturing or 3D printing enables the fabrication of complex parts from functional or biological materials. Conventional 3D printing can be a slow process, where objects are constructed ...

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 ...

3D printing can already create sensors for NASA rovers, rocket engines, safer football helmets, dentures. Name it, and it seems like it can be 3D printed. But the technology is still pretty limited, ...

A Princeton University team has successfully merged electronics and biology to create a functional ear that can “hear” radio frequencies. The tissue and antenna were merged via the use of an “off-the ...

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 ...
