Miura-ori origami-inspired 3D printed ceramics with a soft polymer coating can bend under pressure without breaking

"folding patterns change ceramics from fragile to tough/ flexible... origami pattern that folds/ stays flat, coated with stretchable, biocompatible polymer... flexes/ recovers when compressed in different directions... polymer coating introduced just enough flexibility to prevent sudden breakage under both static and cyclic compression... coated versions consistently showed greater toughness, especially in directions where the original ceramic was weakest... medical prosthetics, impact-resistant aerospace/ robotic components"
