Shape recovery effect of 3D printed polymeric honeycomb : this paper studies the elastic behaviour of different honeycomb structures produced by PolyJet technology

Polymeric honeycombs, with their lightweight, high stiffness-to-weight ratio, and well-developed energy absorption characteristics, have been widely used in engineering applications. In this work, we report the shape recovery effect in a 3D-inkjet-printed honeycomb core. Shape recovery effect, in wh...
