Metamaterials Tag

Researchers dream of designing metamaterials on the computer and then producing them directly on the 3-D printer. Such materials could be used, for example, to direct sound in an unnatural way. Metamaterials have optical, acoustic, electrical or magnetic properties that do not occur in nature. Researchers...

Nowadays, many different additive manufacturing technologies already exist, which are also summarised under the term 3-D printing. More and more materials are therefore also suitable for use in the 3-D printer. Among the most common are metals, alloys, polymers and ceramics. What exactly is 3-D printing? In...
