The purpose of this article is to show the basic characteristics of the so-called pantographic metamaterial. Here we underline how the microstructure provides some exotic properties and, in principle, implies the second gradient nature of this type of metamaterial. Thanks to the development of additive manufacturing technology (especially in the field of metallurgy) we are now able to produce real samples and carry out experimental measurements to validate the proposed models. In this article we show some new experimental tests, obtained by considering pantographic structures printed in stainless steel. Numerical simulations are briefly shown to show the validity of the theoretical model developed to describe the pantographic metamaterial.
