4D printing of reconfigurable metamaterials and devices

T. V. Manen, S. Janbaz, et al.

This innovative research by Teunis van Manen, Shahram Janbaz, Kaspar M. B. Jansen, and Amir A. Zadpoor introduces an exciting single-step method for creating and programming 3D-to-3D shape-changing materials with a modified FDM 3D printer. The breakthrough allows for printing on curved surfaces, leading to the development of complex shape-shifting behaviors in reconfigurable materials and deployable medical devices like bifurcation stents.

Abstract
This paper presents a single-step method for fabricating and programming 3D-to-3D shape-changing materials using a modified fused deposition modeling (FDM) 3D printer. The modification allows printing on curved surfaces, enabling complex shape-shifting behaviors. The method is demonstrated through the creation of reconfigurable materials and deployable medical devices, including bifurcation stents.
