Duke University materials scientists and chemists have shown a way to bring electromagnetic metamaterials into the third dimension using common 3D printers. According to the researchers, the demonstration could revolutionize the rapid design and prototyping of radio frequency applications such as Bluetooth, Wi-Fi, wireless sensing and communications devices. “There are a lot of complicated 3-D metamaterial structures that people have imagined, designed and made in small numbers to prove they could work,” said Steve Cummer, professor of electrical and computer engineering at Duke. “The challenge in transitioning to these more complicated designs has been the manufacturing process. With the ability to do this on a common 3-D printer, anyone can build and test a potential prototype in a matter of hours with relatively little cost.” Source: Inside 3D Printing News
