3-D Printers Open New Design Space for Wireless Devices

05.05.2017 | Duke University | pratt.duke.edu

Researchers at Duke University have 3-D printed potent electromagnetic metamaterials, using an electrically conductive material compatible with a standard 3-D printer.

The demonstration could revolutionize the rapid design and prototyping of radio frequency applications such as Bluetooth, Wi-Fi, wireless sensing and communications devices. Benjamin Wiley and Shengrong Ye, a postdoctoral researcher in his group, created a 3-D printable material that is 100 times more conductive than anything currently on the market.

3D printed metamaterials

The material is currently being sold under the brand name Electrifi by Multi3D LLC, a startup founded by Wiley and Ye. While still not nearly as conductive as regular copper, it might just be conductive enough to create a 3-D printed electromagnetic metamaterial.
