Biodegradable and biocompatible elastomers (bioelastomers) especially the thermoset ones can mimic the mechanical properties of soft tissues, and sustain and recover from various deformations when implanted in a mechanically dynamic environment in the body. 3D printing offers great power to customize sophisticated constructs for a myriad of applications. However, many thermosets require a long-term curing at harsh conditions, which are not compatible with rapid 3D printing processing. 3D printing thermosets remains a challenge. Poly(glycerol sebacate) (PGS) is a representative of thermoset bioelastomers and has been widely used. However, curing of PGS usually requires high temperature and high vacuum. The limited availability of processing methods for PGS greatly restricts the structural design freedom and its further applications. Here, we develop a novel and general strategy to 3D print thermosets including PGS and demonstrated their diverse applications. |
