Shape memory polymers (SMPs) are a promising material for biomedical applications due to their ability to undergo shape recovery when exposed to water, eliminating the need for external heating. This research develops thiol-ene-based SMPs that use water-induced plasticization to lower the glass transition temperature (T_g), enabling minimally invasive applications such as sealing, structural support, and controlled deployment in sensitive environments.

By integrating these SMPs with stereolithography (SLA) 3D printing, the study enables precise fabrication of tubular and complex geometries. Optimization of print parameters ensures defect-free, high-resolution structures with reliable performance. Mechanical and thermomechanical tests, including dynamic mechanical analysis and cyclic recovery studies, evaluate the materials' durability and responsiveness.

This work combines material innovation with additive manufacturing, offering scalable, customizable SMP systems for diverse biomedical uses, from minimally invasive devices to patient-specific implants.
