Abstract Scope Additive manufacturing of elastomers remains challenging due to their inherent mechanical and thermal properties. The types of elastomers that have been explored for 3D printing are still limited; majority of the studies are focused on silicone or polyurethane elastomers. To overcome those limitations and bring new functionalities in 3D printing of elastomers, it is critical to explore new types of elastomers with unique properties. In this talk, I will present our recent work on molecular engineering and 3D printing of polyisobutylene (PIB)-based elastomers. PIB-based thermoplastic elastomers such as poly(styrene-b-isobutylene-b-styrene) (SIBS) have been successfully used for FDM 3D printing. The microphase separated structure of SIBS can be precisely tuned by adjusting the hard to soft block ratio, blending with homopolymers, as well as their chain architectures. The unprecedented versatility in molecular structure enables the fabrication of 3D soft and stretchable structures with widely tunable mechanical properties and excellent biostability.
