Experimental Methods in Pantographic Structures
, 2020 Once a metamaterial has been conceived, designed and built, its expected properties must be experimentally verified, in order to validate the conceptual analysis leading to it and the construction process used to realize it. Using 3D printing technology is not always a trivial task, especially if the designed microstructures are complex and show large ...
