However, the investigations into sandwich structures with 3D printed core are limited in number. These structures can create a meta material behavior with the change of geometry which leads to negative poison ratio of core. Hence, in this article, investigations into sandwich structures with 3D printed core under various loading for comparing their structural responses have been reviewed in detail. Different shapes of 3D printed cores have been reviewed and their specifications are discussed. https://jcamech.ut.ac.ir/article_92168_4bcc180b94a4c7f1ff02495d72258259.pdf
