Hearing aids, mouth guards, dental implants, and other highly tailored structures are often products of 3D printing. These structures are typically made via vat photopolymerization—a form of 3D ...

In recent years, research interest in the 3D printing of metal patterns on plastic parts has grown exponentially, due to its high potential in the manufacturing of next-generation electronics. But ...

"We are interested in using our approach to build 3D complex shapes of biological structures, allowing us to bio-print, for example, life-scale models of tissues or organs," says Alvarez-Castaño.

In this article, we'll explore how this innovative method, which employs multiple acoustic holograms, works and examine its potential applications and limitations. What are Acoustic Holograms, and How ...
