Columbia researchers' AirCode system uses 3D printed air pockets for physical object tagging

Columbia University researchers have developed “AirCode,” a new way of embedding information within a 3D printed part. Patterned air pockets, which could form QR codes and such like, are printed under the surface of an object, and are readable using computational imaging methods. When designing a 3D printed object, the inside of the object is a matter of serious concern. Density and infill pattern, for example, can have a huge effect on the overall strength and function of a part, which means that designers must think carefully about what lies beneath the surface of their 3D printed creation. But […]
